Common CNC machining centers are divided into vertical and horizontal types. Although the appearance and structure are the same, in general, CNC machining centers are mainly composed of the following parts.
(1) Basic components
It is the basic structure, which consists of a bed, a column and a worktable. It is the basic component of a CNC machining center. Most of them are cast iron castings. CNC machining centers must withstand static loads and dynamic cutting loads during machining. Therefore, the rigidity of the bed casting is very high, and it is also the most important component that determines the quality of the CNC machining center.Our offering also includes Cnc Turning Parts, CNC lathes capable of driving tools through at least 2 axes (called X and Z) under G-code control.
(2) Spindle parts
It is composed of spindle box, spindle motor, spindle and spindle bearing and other parts. The start, stop and speed change of the spindle are controlled by the numerical control system, and the cutting tool is involved in the cutting motion through the tool installed on the spindle, which is the power output component of the cutting process. The spindle is the key component of the
CNC Machining Parts, and the quality of its structure has a great influence on the performance of the
Cnc Machining Parts, which determines the machining accuracy and stability.CNC machining is driven by components such as headstock, spindle motor, spindle and spindle bearings. The start, stop and speed of the spindle are controlled by the CNC system. The tool participates in the cutting motion through the tool installed on the spindle, and is the power output component of the cutting process.
(3) CNC system
The CNC system of CNC machining center is composed of CNC device, programmable controller PLC, servo drive system and operation panel. They are CNC machining centers that perform sequential control actions and complete operations during the machining process.
The CNC device is a position control system. The control process is to perform data processing and interpolation operations according to the input information to obtain the ideal motion trajectory information, and then output it to the execution components to process the required workpieces.And Gear Cutting. The processing methods of precision gears include casting, forging and cold rolling. Hot rolling, cutting, etc., among which cutting is the most common.
The function of the servo system is to convert the signal from the numerical control device into the movement of the moving parts of the machine tool. Its performance is one of the main factors that determine the machining accuracy, surface quality and production efficiency of the machine tool. CNC machining centers generally use three control methods: semi-closed loop, closed loop and mixed loop.There are
Lighting Accessories, some lighting parts for assembly; as well as
Precision Grinding Parts,
Hardware Parts and other products. If you want to know more, please contact us, we have a large inventory, we will be happy to serve you!
(4) Automatic tool changing system
It consists of tool magazine, manipulator, drive mechanism and other components. During the machining process, when the tool needs to be changed, the CNC system issues an instruction, and the manipulator (or by other means) takes the tool out of the tool magazine and loads it into the spindle hole. It solves the tasks of automatic storage, selection, transportation and exchange of tools between processes in the multi-process continuous processing after the workpiece is clamped once.
The tool magazine (tool head) is a device that stores all the tools used in the machining process. The tool magazine has disc type, chain type, etc., and the capacity ranges from a few to dozens. The structure of the tool arm also has various forms according to the relative position and structure of the tool magazine and the spindle, such as: single-arm type, double-arm type, etc. Some do not use the tool arm but directly use the movement of the spindle box or the tool magazine to realize the tool change.
The structure of the manipulator has various forms according to the relative position and structure of the tool magazine and the spindle. Some CNC machining centers use the movement of the spindle box or tool magazine to realize tool change without manipulators.
(5) Auxiliary device
Including lubrication, cooling, chip removal, protection, hydraulic, pneumatic and detection systems and other parts. Although the auxiliary system does not directly participate in the cutting motion, it plays a decisive role in ensuring the machining efficiency, machining accuracy and reliability of the CNC machining center, so it is also an indispensable part of the CNC machining center.
