Improvement Measures for Surface Roughness in Precision Parts Processing
2022 / 02 / 14
The process factors that affect the surface roughness in the machining of precision parts mainly include cutting amount, tool geometric parameters and so on. If you want to improve, you need to start from the following aspects: 1. Cutting amount The larger the feed rate, the higher the residual area height and the rougher the part surface. Therefore, reducing the feed amount can effectively reduce the surface roughness value. The cutting speed also has a great influence on the surface roughness. When cutting elasto-plastic materials at medium speed, the surface roughness value of the parts after machining is large due to the easy generation of edged chips and the large plastic deformation. Usually low-speed or high-speed cutting of elastic-plastic materials can effectively avoid the generation of built-up edge, which has a positive effect on reducing the surface roughness value. 2. Tool geometry parameters In the machining of precision parts, the main declination angle, the secondary declination angle and the radius of the tool nose arc have a direct impact on the surface roughness of the parts. In the case of a certain feed rate, reducing the main and secondary deflection angles or increasing the radius of the tool nose arc can reduce the surface roughness value. In addition, appropriately increasing the rake angle and relief angle can reduce the cutting deformation and the friction between the front and rear rake faces, suppress the generation of built-up chips, and also reduce the surface roughness value. After solving these problems, the problem of surface roughness can be greatly reduced.
What Are the Tool Setting Methods for Turning and Milling Compound Machining?
2022 / 01 / 17
The purpose of turning and milling compound machining tool setting is to determine the position of the program origin in the machine tool coordinate system. In layman's terms, tool setting is to control the tool nose points of all the tools of the machine tool at the same point. The essence of tool setting is to initially determine a relative position between the tool and the workpiece. According to this position, the next cutting position is determined according to the size to be processed. 1. Trial cutting method The trial cutting method belongs to the in-machine tool setting method, which is simple to operate and widely used, and is suitable for most situations of lathes. 2. Knife setting The tool setting block belongs to the manual tool setting in the machine, which is low in cost and fast. Without considering the tool setting accuracy, its tool setting efficiency can be said to be the first. The tool setting method of the tool setting block is similar to the trial cutting method, except that the spindle does not rotate during the tool setting. allow. 3. Knife setting instrument Tool setter is an accessory product of CNC machine tools in the rapid development of modern science and technology. It is often used in CNC lathes, CNC milling machines and machining centers. It can be divided into two types: in-machine and several. The tool setting instrument uses the potential of development. Because the number of tools set by the off-machine tool setter is large. High efficiency and wide application. It will have a wide range of application prospects in the future. The working principle of the CNC machine tool determines that when the machine tool returns to the mechanical reference point of its respective motion axis, the machine tool coordinate system is established. Once the reference point is established, relative to the zero point of the
How to Observe the Failure Phenomenon in Precision Machining?
2022 / 01 / 17
In the processing of precision parts, the fixture of the milling machine fails, and there are some obvious failure phenomena, such as the machining accuracy of the parts cannot be guaranteed, the clamping of the parts is not reliable, some components of the fixture are damaged and severely worn, and the devices and mechanisms cannot achieve operational functions. At this time, it is mainly through detection, observation and experimental operation to preliminarily determine the main cause of the fault. Analysis of the cause of the failure: If the various failures of the milling machine fixture are caused by a single cause, the analysis can be carried out according to the general rules. For example, the parts are displaced during the processing process, and the cause may be the failure of the clamping part; precision parts There are regular deviations in the dimensional accuracy of machining, which may be caused by the decline and looseness of the positioning components of the parts; the deviation of the machining accuracy of the parts is consistent, which may be caused by the failure of the tool setting device. If it is caused by multiple reasons, it is necessary to analyze the above single reason before further analyzing the relevant reasons. For example, it is found that the position accuracy of the plane milling fixture has decreased, which may be caused by the wear of the top of the support and limit element, and the imbalance of the linkage clamping mechanism.
What Five Axes Does a Five-axis Machining Center Refer To?
2022 / 01 / 10
Five-axis machining centers have long been important in the aerospace industry, where machined parts follow the aerodynamic form of aircraft. Some machines move the axis of rotation just to position the tool or work outside of the cut. Machines capable of this "3+2" machining can often reach all machined features of a part in one setup. Five-axis machining is to add two rotary axes to the three common linear axes of X, Y, and Z. The two rotating axes of the three-axis (A, B, C) axis have different motion modes to meet the technical requirements of various products. The five axes of a five-axis machining center generally refer to the ability of a CNC machine to move a part or tool on five different CNC axes simultaneously. Standard 3-axis milling takes place on the X, Y, and Z axes. These three linear axes are the directions in which the spindle or part (depending on the machine) can move: X-axis: left to right, Y-axis: front-to-back, Z-axis: up and down. Five-axis machining centers also use two axes of rotation: A, B, and C. A axis: rotate around the X axis, B axis: rotate around the Y axis, C axis: rotate around the Z axis. The use of rotary axes in a five-axis machining center means that the machine can move a part or cutting tool (spindle head) around one of the previously established linear axes. Different machining equipment will use different combinations of axes (A and B, B and C, or A and C), each configuration suitable for a different type of machining. The 5-axis machining process is also very similar to the 3-axis CNC machining process. However, it has some very important features that provide these two extra axes and greater cutting flexibility. In a five-axis machining center, the spindle and tool move along three axes. However, there are other rotations around the X-axis (called the A-axis), the Y-axis (called the B-axis), and the Z-axis (called the C-axis). Five-axis machining centers c
Introduction of Micro Gear Cutting Method
2022 / 01 / 10
Gear hob hobbing is to use a hob to cut gears on a gear hobbing machine. During micro gear hobbing, the tooth profile of the hob must be micro-machined. Since the micro-gear has a very small tooth profile, in addition to the tooth profile error of the hob, errors such as tool tip runout, tool tip run-out, and circular motion will also occur, which seriously affect the accuracy of the micro-gear. At present, the common micro gear processing method is cutting, and there are two methods for cutting, namely 5-face milling and 2-face hobbing. The 5-cut process requires multiple offset passes on a 3-axis CNC machine, while the 2-cut process can be achieved with just two passes on a more complex 5-axis CNC machine. While the 5-cut method has been used reliably for decades in the automotive industry, more and more factories are turning to the faster and less expensive 2-cut process. Each cutting method for micro gears has its own unique geometry. A 2-cut gear will have ring teeth of consistent height and a tapered root width, while a 5-cut gear will have a higher outer diameter than the inner diameter with a constant root width. So, on a 2-tooth gear set, the micro gears only contact the ring gear at the center of the teeth, while the micro gears in a 5-tooth gear slide the entire length of the tooth flanks.
How to Judge the Precision Machining Error of Turning Parts?
2022 / 01 / 04
The influence of geometric errors and working errors of lathes on machining accuracy makes the actual geometric parameters (size, shape, position) of the parts processed do not match the ideal geometric parameters, which affects the processing quality. Therefore, in machining, the error is inevitable, but the error must be within the allowable range. Through error analysis, grasp the basic law of its change, so as to take corresponding measures to reduce processing errors and improve processing accuracy. Processing errors are mainly divided into the following three types: ① Random error Random error is the error in which the absolute value and sign cannot be changed predetermined when the same value is measured multiple times under the same conditions. There are many factors that produce random errors, and most of these factors are accidental and unstable. ②System error System error refers to the error in which the size and sign of the error remain unchanged or change according to a certain rule when the same measurement value is repeatedly measured under the same conditions. That is, the former case is the fixed value system error, and the latter case is the straightening system error. ③Large error Gross error refers to an error that exceeds expectations under specified conditions. Preventive measures to reduce errors 1 Measurement method. The measurement method refers to the combination of the measuring instruments and measurement conditions used in the measurement. Before measurement, the best measurement method should be determined according to the characteristics of the measured object. 2 Measurement accuracy. Measurement accuracy refers to the degree of agreement between the measurement result and the true value. The accuracy of the effective value of the measurement result is determined by the measurement accurac
Which Manufacturing Process is Right for Your Industry?
2022 / 01 / 04
Every industry has different manufacturing needs, and there are many options when choosing the right method to create custom parts. We have worked with thousands of customers from all walks of life and integrated key observations to help you choose the right process for your next project. 1. Aerospace The vast majority of engineers and product designers in the aerospace industry use CNC to machine their custom parts because of its high precision and a range of qualified materials and finishing options. Sujia cooperates with aerospace companies, and we see that they apply a lot of machining because they can design strict tolerances for metals such as aluminum, steel, and titanium. For workpieces that do not use sheet metal processing or manufacturing, Fused Deposition Modeling (FDM) and Selective Laser Sintering (SLS) are common choices because they achieve complexity and scalability at a lower cost. 2. Medical equipment The most popular process for engineers and product designers in this industry is direct metal laser sintering (DMLS). Metal 3D printing using DMLS provides strength, precision and complex geometry, while the cost is only a small part of traditional processing. For non-metallic parts and prototypes, SLS 3D printing is also a popular choice. When high-precision and customized materials become the main focus, CNC machining is still the manufacturing method required for some medical device jobs. 3. Technology and Consumers Although parts in the technology industry can be manufactured using a variety of processes, they may be most suitable for FDM manufacturing. FDM provides higher strength, material selection and greater capacity. More elaborate models for rapid prototyping are ideal for photopolymers, such as PolyJet rigid and rubber-like materials, including the option to build multi-material demonstration parts. For more cosmetics and end-consumer products, the i
Cnc Turning Stainless Steel Thread Processing Experience, Very Practical ! ! !
2021 / 12 / 29
Stainless steel is a relatively difficult material to process, especially for thread processing. After CNC cutting, the surface roughness of the thread is too poor. The phenomenon of scale-like waves and knife gnawing are the most common phenomena encountered in stainless steel thread turning. The reasons for these phenomena are as follows: (1) The clearance angles on both sides of the thread turning tool are too small, and the friction between the cutting edges on both sides and the thread surface will deteriorate the processing surface. The influence of the thread rotation angle on the actual clearance angles of the cutting edges on both sides must be considered during processing. (2) The rake angle of the thread turning tool is too small, the cutting edge is not sharp enough, and the chips cannot be cut smoothly, but are partially squeezed or torn off, which must cause the thread surface to be very rough. When the front angle is too large, the strength of the cutting edge is weakened and it is easy to wear, chip, and pierce the knife, which is more likely to cause vibration and cause ripples on the thread surface. Therefore, the appropriate rake angle should be selected according to the different materials of stainless steel. When turning concentrated sulfuric acid resistant stainless steel threads, a smaller rake angle should be used than turning 2Cr13 stainless steel threads. The cutting edges on both sides of the turning tool should have very narrow cutting edges to avoid rapid wear of the cutting edges. When cutting 2Cr13, 1Cr17, 4Cr13, the cutting edge should be as sharp as possible, otherwise it will not be easy to achieve the required good surface roughness. (3) The thread cutter blade is blunt, and the actual rake angle and rear angle are changed from large to small. The chips are severely squeezed during the formation process, which increases the cutting force during the cutting process and increases the vibra
Numerical Control Turning Processing Technology and Analysis
2021 / 12 / 29
Process analysis is the preliminary process preparation work for hardware CNC turning processing. Whether the process is reasonable or not has an important influence on the later programming, the processing power of the machine tool and the processing accuracy of the parts. In order to compile a reasonable and useful processing program, the programmer is required not only to understand the operating principle, functional characteristics and structure of the CNC lathe. To grasp the programming language and programming format, you should also be proficient in the processing technology of the workpiece, determine the reasonable cutting amount, and correctly select the tool and the workpiece clamping method. Therefore, it is necessary to follow the general process guidelines and combine the characteristics of CNC lathes to analyze the CNC turning process of hardware accessories in detail. The main content of the analysis includes: analyzing the processing requirements and rationality of the parts according to the processing drawings; inferring the clamping method of the processed parts on the CNC lathe; the processing order of the appearance of each processed part, the feed route of the tool, and a series of supplies Preparations such as: selection of tools, fixtures and cutting parameters. The analysis of the part drawing is the primary task of drawing up the CNC turning process. Mainly carry out the analysis of the scale labeling method, the analysis of the summary elements, and the analysis of the accuracy and skill requirements. In addition, it is necessary to analyze the rationality of part structure and processing requirements, and select process benchmarks. Huaying Chuang Precision Machinery's CNC turning process is divided into the following steps 1. Analysis of scale marking method The scale marking method on the part drawing should be used to the processing characteristics of the CNC lathe, and the sc
Introduction to Cutting Processing of Precision Gear Processing Methods
2021 / 12 / 20
Precision gear processing methods include casting, forging, cold rolling, hot rolling, cutting, etc., of which cutting is the most common. According to the principle, cutting processing can be divided into two forms, namely the profiling method and the fan forming method. The profiling method is the process of cutting the quality of the gear by using tools with the same contour shape as the two sides of the tooth groove of the gear to be cut. However, the profiling method has low production efficiency and low processing precision, and is suitable for single-piece small batch production of large modules with low precision. Fan Cheng method, also known as generation method, is currently the most commonly used method in gear processing, such as gear shaping, gear hobbing, gear grinding, etc. The gear blank makes the two still move according to the original transmission ratio, and at the same time the tool moves at the cutting speed, and the tooth profile conjugated with the tool selection gear can be machined on the gear blank. Precision gear processing method: Classification: Forming method: vertical milling, horizontal milling; Generating method: hobbing, slotting, quilting, grinding, shaving. The processing technology of cylindrical gears usually adopts different technological schemes due to the difference of gear structure shape, precision grade, production batch and production conditions.
What Are the Surface Treatment Processes for Hardware Parts?
2021 / 12 / 20
The surface treatment of hardware parts is another common post-processing technology, and its surface processing subdivisions can be divided into: painting processing, electroplating technology, surface polishing processing and so on. 1. Spray paint processing: At present, most hardware factories use spray paint processing technology when producing large hardware products, and use spray paint to avoid rusting of hardware parts, such as: electrical enclosures, handicrafts, etc. 2. Electroplating technology: Electroplating is a common processing technology in the processing of hardware parts. The surface of the hardware parts is electroplated with modern technology to ensure that the product will not be moldy or embroidered after long-term use. Common electroplating processing includes: screws, stamping parts, auto parts, small accessories, etc. 3. Surface polishing process: Surface polishing process is generally used for daily necessities. For example, through the surface burr treatment of hardware products and the processing of spiral bevel gear parts, spiral bevel gears are metal parts made by punching, so the punching corners of spiral bevel gears are very sharp. The sharp corners need to be polished to a smooth surface to avoid damage to the equipment during use. Polishing is to keep the product bright, so we use a wide range of precision metal processing technologies, especially for products that are prone to pilling and burrs. Polishing is an essential step. Hardware parts not only have a wide range of types and specifications, but also play an irreplaceable role in equipment for various applications. Hardware parts processing is an ideal part that uses raw materials to complete various processing techniques.
Precision Requirements for Machining Precision Gears
2021 / 12 / 07
Precision gears are widely used in today's machinery industry. As an important product in the gear industry, precision gears play a very important role in the gear industry. When processing precision gears, in order to ensure certain performance when using precision gears in the future, they usually have very high standard accuracy requirements. Now let's introduce the precision requirements for machining precision gears! 1. When processing precision gears, there should be a certain amount of backlash between the non-working tooth surfaces of precision gears to facilitate the storage of lubricating oil and reduce the installation error of precision gears. 2. In the production process of precision gears, it is necessary to ensure good contact between the tooth surfaces during operation, so that the load of the precision gears can be evenly distributed. 3. The rotation angle error of the precision gear should be within the specified range, so that the design of the precision gear can be more stable and the transmission can be reduced, and the vibration and noise during work can be reduced. 4. For the accuracy of the transmission movement, the angular error of the precision gear within a circle also has a certain range.
Is It Necessary to Warm Up the CNC Machine Every Morning when It is Turned On?
2021 / 12 / 07
Do you have such experience: When you turn on the machine every morning, the machining accuracy of the first part is often not good enough; The accuracy of the first batch of parts is often very unstable, and the probability of failure in high-precision machining is extremely high, especially the position accuracy. Factories without precision machining experience often attribute the instability of accuracy to equipment quality problems. And factories with precision machining experience will pay great attention to the environmental temperature and the heat balance of the machine tool. They know very well that even high-precision machine tools can only obtain stable machining accuracy under a stable temperature environment and thermal equilibrium. In the case of high-precision machining and production after the machine is turned on, preheating the machine tool is the most basic common sense of precision machining. 1. Why do we need to warm up the machine tool? The thermal characteristics of CNC machine tools have an important impact on machining accuracy, accounting for almost half of the machining accuracy. The main shaft of the machine tool, the guide rails used by the XYZ motion axis, the lead screw and other components will be heated and deformed due to load and friction during the movement, but the final influence on the machining accuracy in the thermal deformation error chain is the relative difference between the main shaft and the XYZ motion axis. Displacement of the worktable. The machining accuracy of the machine tool in the state of long-term shutdown and the state of thermal equilibrium is quite different. The reason is that the temperature of the spindle and each motion axis of the CNC machine tool is relatively maintained at a certain fixed level after running for a period of time, and With the change of proc
Which Parts Are Mainly Processed by CNC Lathes?
2021 / 12 / 01
When processing hardware on CNC lathes, all rotating parts that can be clamped by ordinary lathes can be processed by CNC lathes. The CNC lathe has high machining accuracy in the hardware processing process, has the characteristics of linear arc interpolation, automatic speed change, and its technical scope is much wider than ordinary machine tools. The CNC lathe has high rigidity and high precision in manufacturing and tool setting instruments. It can easily and accurately enter manual correction and automatic correction, so it can process parts that require dimensional accuracy. In addition, the tool movement of CNC turning is realized by high-precision interpolation movement and servo drive. In addition, the machine tool can also process parts with high rigidity, high manufacturing accuracy, and shape accuracy of busbar straightness, roundness, and cylindricity. For arcs and other curved contours, the machining shape is closer to the geometric shape required by the engineering drawing than the profiling lathe. The CNC lathe has the function of cutting at a fixed line speed. It can cut the tapered surface and the end face with a good line speed, can make the surface roughness value after turning small and uniform, and can machine parts with small and uniform surface roughness values. On CNC lathes, not only straight threads, tapered threads, and end-face threads with a lead can be machined, but also threads with a lead and the smooth transition between them can be machined. When turning the thread on the CNC lathe, the rotation of the spindle does not need to be alternately replaced like an ordinary lathe, and it can be continuously cycled until it is completed, so the thread processing efficiency on the CNC lathe is very high.
CNC Machining Center Processing Mechanical Thread Parts
2021 / 12 / 01
At this stage, the thread processing types of mechanical thread parts in the market mainly include internal thread, single thread, variable pitch thread, external thread, multi-thread thread, and fixed-pitch thread. In the past, the machine tool processing technology was based on the thread line cutting and processing of parts. However, mechanical processing is based on turning processing technology, which drives the tool through a mechanical transmission belt to realize part processing. When processing mechanical threaded parts, CNC machining centers are often used for parts processing. This is because CNC machining center processing technology can greatly improve the machining accuracy of mechanical threaded parts, while ensuring the safety of parts processing and the quality of parts,improve the processing efficiency of threaded parts. The lathe processing method can effectively improve the quality of parts processing and greatly shorten the processing cycle of parts. When the CNC machining center processes mechanical threaded parts, it needs to apply coordinate, size measurement and other technical means to grasp the size and position of mechanical threaded parts in a multi-directional manner, for example, the points, lines, and surfaces of mechanical screw parts Equal azimuth angle, these data are an important basis for realizing reasonable programming, because when CNC machining of mechanical thread parts, it is necessary to avoid large accumulation of errors. In order to achieve this goal, it is often necessary to modify some of the dimensions in the local scatter annotation. When applying numerical control technology, it is necessary to ensure that the use of tool paths can be as simple as possible, so that the CNC machining center can carry out the cutting program in an orderly manner, taking into account that the CNC machining center should avoid contour errors when processing mechanical thr
Features and Treatment Methods of Economical CNC Lathes
2021 / 11 / 23
Economical CNC lathes are developed on the basis of ordinary lathes, but their degree of automation has been greatly improved. The automatic control system of the economical CNC lathe is mainly organized into a single piece. After the control program, the longitudinal and transverse feed equipment and the tool change equipment of the machine tool are controlled to automatically complete the processing of the parts. The processing methods of economical CNC lathes are also different. After the program of the economical CNC lathe is running, the tool does not return to the zero point. Generally, the reason for this phenomenon is mainly caused by the fault of the control system. The tool requires low-speed operation during feeding or processing. At this time, the stepping motor has a low working speed and low-voltage power supply is used. When the program returns to the zero point, a quick return is required. At this time, the stepping motor is required to run at a high speed and a high-voltage drive power supply is used. Increase the output torque and ensure normal return to zero. There is a switching transistor that controls the output of the high-voltage drive power supply. When the switching transistor is damaged, the high-voltage power supply cannot be turned on and the output torque of the stepping motor cannot be turned on when the high-speed return to the zero point occurs. A fault can be eliminated by replacing the switching transistor.
What Needs to Be Done Before the CNC Lathe Machine is Used?

If any errors are found, they should be dealt with immediately. Check the sockets and wiring on the CRT unit. The ground wire is required to have an outstanding ground wire. When measuring the ground wire of
The Whole Process of Cnc Lathe Programming
2021 / 11 / 15
As a CNC lathe operator, it is necessary to understand some necessary programming knowledge. As we all know, the reason why the CNC lathe can actively process parts of different shapes, sizes and high precision is because the CNC lathe is "received" and "processed" by its CNC equipment according to the pre-programmed processing program, so as to realize the processing of the parts. For active machining control, when machining parts with a CNC lathe, the first thing to do is to write a machining program. The whole process from analyzing the drawing of the part to obtaining the control medium required by the CNC lathe is called programming, and the specific programming is as follows: 1. Drawing analysis: According to the drawings and technical documents of the processed parts, analyze the general shape, related markings, dimensions, accuracy, surface roughness, roughness, blank types, number of pieces, materials, and heat treatment requirements of the parts to form a preliminary processing plan . 2. Auxiliary preparation: Determine the machine tool and fixture, machine tool coordinate system, programming coordinate system, tool preparation, tool setting method, tool setting point positioning and measuring mechanical clearance according to the analysis of the drawings. 3. Drafting the processing technology: drafting the processing technology plan, determining the processing method, the allocation of processing lines and allowances, positioning and clamping methods, and the reasonable selection of machine tools, cutting tools and cutting parameters. 4. Numerical calculation: Before compiling the program, some unknown coordinate values of the processing track need to be calculated. As the program input data, it mainly includes: numerical conversion, proportional chain calculation, coordinate calculation and auxiliary calculation, etc. For complex processing curves and curved surfaces, accounting machines must be

The non-transferable plasma arc tungsten electrode is connected to the negative end of the power supply, and the nozzle is connected to the positive end of the power supply. The plasma arc body is generated between the tungsten electrode and the nozzle. Under the pressure of plasma gas, the arc column is ejected from the nozzle to form a plasma flame. .
Several Operation Methods of CNC Machining Thread Cutting
2021 / 11 / 04
In the process of processing, facing the different thread requirements of different customers, the methods we use are also different. The trapezoidal thread is longer, the cutting depth, the cutting force is high, the precision is high, and the processing is difficult. When machining ordinary threads, if the cutting depth of each tool is the same, the force on the cutting edges on both sides of the thread turning tool will increase sharply as the removal rate increases. Increased, resulting in decreased thread accuracy and tool damage. Therefore, it is necessary to pay attention to the need for multiple cycle feeds during cutting, and the cutting depth must be reduced in accordance with a certain proportion each time. Both internal and external threads are relatively common, and the processing is generally more difficult. Small, pay attention to the calculation of the bottom of the thread. The main methods of thread cutting on CNC lathes are as follows: 1. Grooving rough cutting method, first use a grooving tool smaller than the width of the thread turning tool head to cut a groove, and then use the thread turning tool for thread processing. Large pitch is often used, but the operation and programming are extremely cumbersome. 2. Staggered cutting method, the thread car is staggered in the direction parallel to the left and right side of the tooth profile, until the bottom of the tooth, which is very suitable for large thread cutting, but the programming is more complicated. 3. The oblique advance method, pointing
The Management and Use of CNC Lathe Processing
2021 / 11 / 04
The use of CNC lathe processing requires the careful use of the operator and must rely on scientific management. A perfect management system and scientific production mode are effective means to improve production efficiency. 1. Establish a sound and complete management system to effectively control and supervise the work of the relevant personnel of the CNC lathe, so that the entire process of the operation and operation of the lathe is controlled. 2. Strengthen the training of technical personnel and technical worker management personnel. The training of CNC machining is always a long-term work and a process of continuous improvement. Through training craftsmen, they can compile more simplified CNC machining processes, simplify procedures, and shorten processing time; technical workers can improve operating skills; managers can better understand the characteristics of CNC equipment, process control, and implement management with modern production management concepts. 3. Scientifically organize production. Improve the problem of work stoppage and unbalanced production capacity, increase the operating rate of CNC lat
