Brass is an alloy of copper and zinc. If it is only composed of copper and zinc, it is called ordinary brass. Brass is often used to make valves, water pipes, connecting pipes for internal and external air conditioners, and radiators. Mechanical properties of ordinary brass characteristics: Due to the different zinc content in brass, the mechanical properties are also different, and the mechanical properties of brass vary with the zinc content. For brass, the room temperature strength increases with increasing zinc content until the zinc content increases to about 45%. If the zinc content is further increased, the strength decreases sharply. The room temperature plasticity of brass always decreases with the increase of zinc content. Properties of special brass: α phase and β phase in special brass are multi-component complex solid solutions, which have a greater strengthening effect, while α and β phases in ordinary brass are simple Cu-Zn solid solutions, and their strengthening effect is low. . Although the zinc equivalents are equivalent, the properties of multicomponent solid solutions are different from those of simple binary solid solutions. Therefore, a small amount of multi-component strengthening is a way to improve the properties of the alloy. Lead-brass characteristics: Lead is actually insoluble in brass, and is distributed on the grain boundary in the state of free particles. Lead brass has two types: α and (α+β) according to its organization. Alpha lead brass can only be co

Maintenance And Maintenance Of Metal Molds
2022 / 05 / 09
Metal molds are used in industrial production to use various presses and special tools installed on the presses to make metal materials into parts or products of the desired shape through pressure. Such special tools are collectively referred to as metal molds. All kinds of tools and products we use in our daily production and life, ranging from the base of the machine tool, the shell of the machine body, to the shell of a screw, button and various household appliances, are all closely related to the mold. . The shape of the mold determines the shape of these products, and the processing quality and precision of the mold also determine the quality of these products. Due to the different materials, appearance, specifications and uses of various products, molds are divided into non-plastic molds such as casting molds, forging molds, die-casting molds, stamping molds, and plastic molds. Mold maintenance and maintenance 1: After the mold is used for a long time, the cutting edge must be sharpened. After grinding, the cutting edge surface must be demagnetized, and must not be magnetic, otherwise it is easy to cause blockage. 2: Springs and other elastic parts are most easily damaged during use, and usually break and deform. The method to take is to replace. During the replacement process, you must pay attention to the specificati

The HistoricAl Origin Of The Development Of Gears
2022 / 04 / 23
In the West, in 300 BC, the ancient Greek philosopher Aristotle expounded on the problem of transmitting rotational motion with bronze or cast iron gears in "Mechanical Problems". Famous Greek scholars Aristotle and Archimedes have both studied gears, and the famous Greek inventor Gutisibios evenly inserted the pins on the edge of the circular plate workbench to make it mesh with the pin wheel, He applied this mechanism to engraving. This is about 150 BC. In 100 BC, the Alexandrian inventor Herron invented the odometer, in which gears were used. In the 1st century AD, a gear transmission was also used in the waterwheel milling machine made by the Roman architect Pidobis. By the 14th century, gears began to be used in clocks. In the early years of the Eastern Han Dynasty (1st century AD), there were already herringbone gears. The compass car and Jili drum car that appeared in the Three Kingdoms period have adopted gear transmission systems. The water-rotating continuous grinding invented by Du Yu in the Jin Dynasty transmits the power of the water wheel to the stone mill through gears. The earliest record of the gear transmission system in the history books is the description of the water-borne armillary sphere made in 725 by a party of Tang Dynasty and Liang Lingzan. The water transport instrument and Xiangtai (see ancient Chinese timepieces) made in the Northern Song Dynasty used a complex gear system. In the Ming Dynasty, Mao Yuanyi's "Wu Bei Zhi" (written in 1621)
What Are The Functions Of Gears
2022 / 04 / 23
To transmit power, change the speed and direction of movement. Gears are mechanical elements with gears on the rim that continuously mesh to transmit motion and power. Gears have been used in transmission for a long time. At the end of the 19th century, the principle of generating tooth cutting hair began to appear, and then, under the research of people, the theory appeared one after another using special machine tools and tools to cut teeth. With the development of production, the smoothness of gear operation is concerned. The working principle of gears is to rely on the meshing between the gear teeth and the chain links to transmit the direction of motion and power. The advantages of gears are high transmission efficiency, large transmission ratio, large transmission torque and long service life. But it also has disadvantages, such as heavy weight, loud noise, small transmission distance, and high friction requiring frequent lubrication. Gears and gear products are important basic parts of mechanical equipment, which play a very important role in the overall power system. It can be said that most of the main transmission components of the current mechanical equipment are gear transmission.
The Difference Between Rough Cutting and Fine Cutting of Precision Machining Parts
2022 / 03 / 23
The common processing methods in the processing of precision mechanical parts are turning and milling parts, and some common precision parts are milling parts or turning parts. After the workpiece has been roughly cut, the entire workpiece is actually very close to the appearance and size required by the workpiece itself, but at this time there is still a lot of allowance on the surface of the workpiece for fine cutting. Smoother and more accurate in size. Under normal circumstances, the workpiece processed by precision mechanical parts can achieve the required appearance and size of the workpiece after one rough cutting and one fine cutting. But not all workpieces need only one cut, and some parts of some workpieces may require multiple rough cuts. At the same time, there are also some workpieces whose precision requirements are not too high or the cutting amount is very small, and it may also only need one fine cutting to meet the requirements of the workpiece. Rough cutting in the machining of precision mechanical parts requires a larger cutting force than fine cutting because the workpiece needs to be cut. Remove the allowance, and the surface properties after the effect should not be too rough. The fine cutting of precision mechanical parts processing is to meet the requirements of the workpiece surface performance and dimensional accuracy. Therefore, the tools used for fine cutting also need to be very sharp, because the cutting amount is small, so the measurement accuracy is required. very high. In fact, there are many parts that we can't see that are inseparable from the processing of precision mechanical parts, such as very small nuts in mobile phones, because these nuts are actually customized according to the needs of mobile phone manufacturers, and there are almost no What standard, and the precision requirements are very high, so almost all of them rely on precision machining.

The Advantages of Precision Machinery Five-axis Machining Center
2022 / 03 / 14
1. Reduce processing time and improve processing accuracy. The biggest feature of the five-axis linkage machining center is that one-time clamping can process all five surfaces. This is the so-called machining angle avoidance. If it is a linkage machine tool, the C axis can rotate without limit, and the A axis can rotate about 130 degrees. These device characteristics allow for interference-free machining. The advantage of this is that the processing can be completed in one clamping, that is, repeated positioning errors caused by multiple clampings are avoided. At the same time, one clamping also saves a lot of time and improves work efficiency. It can reduce the time from product to delivery and reduce the amount of inventory. 2. Reduce equipment investment cost, workshop area and workshop quantity. Five-axis linkage machining center, left and right composite processing machines, usually with car function, from lathes to milling machines to vertical mills can be included. Everyone knows that the price of vertical grinding equipment is very expensive. It is found that the five-axis is more cost-effective. Previously, everyone's production and processing may be mainly divided into engineering. The problem with this production method is that there is a lot of waiting time that cannot be eliminated. However, the engineering-intensive production represented by the five-axis composite processing equipment only requires the initial waiting time for debugging, and with the popularization of various types of machine simulation software, programming can be completed only by importing blank data, which can also be greatly shortened. Preliminary preparation. Therefore, at present, auto parts and high-end manufacturing are basically based on five-axis. We are a custom factory, Main business scope is: CNC Turning parts, CNC Machining Parts, Gear Cutting parts,4 Axis Machining parts
What Are the Reasons for the Failure of Precision Parts Processing?
2022 / 03 / 07
With the rapid development of the processing industry, we will encounter various reasons during processing. The products will be affected by processing and the quality will decline. So what is the reason for the failure of precision parts processing? The reasons for the failure of precision parts processing can be summarized into four aspects: material, installation and use, processing and design. 1. Material reasons Improper material selection is the main reason for material failure. Most often, designers make decisions based solely on the material's conventional performance indicators, and the defects of the material itself are also the cause. 2. When installing and using the parts that have already failed, if the fit is too loose, too tight, can not be fixed, poor alignment and improper operation may cause the use of failure. 3. In terms of processing, various defects will be formed due to poor processing technology control, which will cause failure. If the heat treatment process is not properly controlled, it will lead to overheating, lack of tempering, decarburization, etc. Overheating or overburning, etc. Poor cold working process will result in too low brightness, too deep knife marks, grinding cracks, etc., which can lead to the failure of parts. 4. Design reasons:One is that the parts fail due to the unreasonable structure and shape of the design. For example, there are obvious stress concentration sources in the high stress area of the parts. The second is the wrong estimation of the working conditions of the parts, such as the lack of estimation of the possible overload in the work, so that the bearing capacity of the designed parts is insufficient.
What Are the Advantages of Stainless Steel Bearings?
2022 / 03 / 07
There are many kinds of bearing materials. Stainless steel may be the most common bearing material. Stainless steel bearings have certain advantages for ordinary bearings. According to the understanding, the following advantages of stainless steel bearings are summarized. Characteristics of stainless steel bearings: The bearing rings and rolling elements are made of AISI SUS440C stainless steel, which is vacuum quenched and tempered, and the cage and sealing ring skeleton materials are made of AISI304 stainless steel. Compared with ordinary bearing steel, stainless steel bearings have stronger anti-rust and anti-corrosion properties. Choose appropriate lubricants, dust caps, etc., and can be used in the environment of -60°C~+300°C. Stainless steel deep groove ball bearings are resistant to corrosion caused by moisture and several other media. These single row deep groove ball bearings, like standard deep groove ball bearings made of carbon-chromium steel, have deep bearing raceway grooves, and the fit between the bearing raceway and the ball is extremely high. Stainless steel bearings are widely used in food processing, medical equipment, and pharmaceutical machinery because of their high mechanical strength and large load capacity. Advantages of stainless steel bearings: 1. Excellent corrosion resistance: stainless steel bearings are not easy to rust and have strong corrosion resistance. 2. Washable: Stainless steel bearings can be washed off without having to re-lubricate to prevent rusting. 3. Can run in liquid: Due to the material used, we can run the bearing and bearing seat in liquid. 4. Slower depletion: AISI 316 stainless steel does not require oil or grease for corrosion protection. Therefore, if the speed and load are low, lubrication is not necessary. 5. Hygiene: Stainless steel i
What Are the Advantages and Disadvantages of CNC Machining?
2022 / 03 / 01
CNC machining directly means that it is computer numerical control, which is a processing technology widely used in the manufacturing industry. For example, the machining of curved surfaces is almost impossible to process with ordinary machine tools without CNC. In addition, CNC can easily realize a flexible manufacturing system. Ordinary machine tools are processed by people directly controlling the machine tools, while CNC machines are controlled by people by controlling the CNC machining system, so as to achieve more complex and higher-speed processing. CNC machining can greatly reduce the number of tooling, and machining parts with messy shapes does not require messy tooling. If you want to change the shape and size of the part, you only need to modify the part processing program, which is suitable for new product development and modification. The processing quality is stable, the processing precision is high, and the repeatability is high, which is suitable for the processing requirements of aircraft. In the case of multiple types and small batches of production, the production efficiency is high, which can reduce production preparation, machine tool adjustment and process inspection (process inspection refers to the process of preventing unqualified products from flowing into the next process. The inspection time of the main process elements of quality is calculated by the machining center, and the cutting time is reduced due to the use of the optimal cutting amount. In addition, it is possible to process complicated surfaces that are difficult to process by conventional methods, and even some unobservable machining can be processed. part. The price of ordinary milling machines is low, but the efficiency of mass production is low, the processing quality is greatly affected by the technical level of the operators, and the processing consistency is not good. CNC machining has high efficiency in ma
Why Does the Machining Accuracy of Precision Hardware Parts Deteriorate?
2022 / 03 / 01
With the continuous improvement of current science and technology, our technicians can know that there are many more processed products around us, or processing technology, and the same is true for hardware processing, so why is the processing accuracy of hardware worse? The first factor is the poor machining accuracy of the part itself. Generally speaking, if the dynamic error between the shafts is not adjusted properly during the installation, or the change in the shaft transmission chain due to wear will affect the machining accuracy of the hardware. Generally speaking, the accuracy caused by this type of error can be re-adjusted to the compensation amount. If the error is too large and an alarm occurs, it is necessary to check the servo motor to see if its speed is too high. The second factor is that the overshoot of the machine tool during operation will also affect the machining accuracy. It may be due to the short acceleration and deceleration time. Properly extend the change time. Of course, it is also very likely that the connection between the screw and the servo motor is loose. The third factor is that due to the excessive roundness caused by the linkage of the two axes, the axial deformation of the circle is not adjusted properly by the machine, the compensation of the lead screw gap of the axis is not correct or the axis positioning is offset, which may affect the processing of the hardware accuracy has an impact.
Why Are There Many Burrs in Cnc Machining of Stainless Steel?
2022 / 02 / 21
The CNC machining and cutting process is often accompanied by the generation of burrs, but when CNC machining stainless steel, why are there always many burrs? To solve the above questions, the technicians simply shared their practical experience: 1. Stainless steel material factors: Stainless steel may contain elements such as chromium, nickel, molybdenum, titanium, nitrogen, etc., which are relatively soft, and at the same time, the nickel element is high, so when cutting at high temperature, a sticky knife will occur, resulting in an increase in burrs. 2. Improve the tool: The tool is not sharp enough, because tool wear has a great influence on the formation of burrs. When the tool wears to a certain extent, the arc of the tool tip increases. After the tool is used to a certain extent, the cutting edge can be updated; when machining precision parts, it is even more important to Use circular chamfers to reduce burrs. Under the same cutting conditions, diamond tools are more conducive to inhibiting burr formation than other tools. 3. Tool nose entry and exit sequence: Not only the size of the burr in the exit direction of the tool is increased, but also the burr will be generated in the cutting direction of the tool; 4. Modify the milling parameters, increase the size of the feed rate and adjust the direction, etc.; Burrs not only reduce the accuracy and quality of parts, but also affect the function of parts, and sometimes even lead to safety accidents. Dealing with burrs is a non-productive process, and improper removal can also lead to the scrapping of the entire product, resulting in financial losses. If CNC machining stainless steel has a lot of burrs, can you try the solution from the experience shared above?

Does the CNC Lathe Need Oil Change Maintenance?
2022 / 02 / 14
CNC lathes require oil change and maintenance, which many people have doubts about. Let's answer it for you below! The fully automatic CNC lathe is the same as your car. After buying it, you must pay attention to the hygiene of the countertop, so that dust and iron filings cannot enter the track. The harm that will be caused in the future is that the accuracy will become worse and the hand feel will become heavier. It is very heavy and laborious, so the new automatic CNC lathe should change the oil once a month in the early stage, once every three months in the next year, and three times in the first three months. When the oil of the fully automatic CNC lathe is changed, the impurities in the CNC lathe track will also be reduced. It will flow into the oil tank along the new oil, and will not stay in the track and will not scratch the track. The daily maintenance of the automatic CNC lathe is as follows: 1. Check the lubricating oil level to ensure the lubrication of the machine tool. 2. Check whether the coolant in the coolant tank is sufficient, and it cannot be increased in time. 3. Check the oil level of the pneumatic triplet, which is about 2/3 of the height of the entire oil pipe.
