CNC machine:

Turning, milling, planing, grinding, boring, drilling, EDM, shearing, bending, laser cutting, etc. are all mechanical processing methods. The so-called mechanical processing is to process metal blank parts into the required shape, including dimensional accuracy. and geometric accuracy. The equipment that can complete the above functions is called a machine tool. CNC machine tools are developed from ordinary machine tools. CNC means digital control.

After the CNC system is installed on the machine tool, the machine tool becomes a CNC machine tool. Of course, the development of ordinary machine tools to CNC machine tools is not just as simple as adding a system. For example, from the development of milling machines to machining centers, the structure of the machine tools has changed. The most important thing is the addition of tool magazines, which greatly improves the accuracy. The main function of the machining center is the functions of milling, boring and drilling.

The CNC equipment we generally refer to is mainly index-controlled machine tools and machining centers.

Machining center refers to a CNC machine tool equipped with a tool magazine, with automatic tool change function, and multi-process processing after clamping the workpiece at one time. The machining center is a highly mechatronic product. After the workpiece is clamped, the CNC system can control the machine tool to automatically select and replace tools according to different processes, automatically set the tool, automatically change the spindle speed, feed, etc., and can continuously complete drilling, boring, Milling, reaming, tapping and other processes. As a result, the workpiece clamping time, measurement and machine tool adjustment and other auxiliary process time are greatly reduced, and the processing shape is more complex, the precision requirement is high, and the variety is frequently replaced, it has a good economic effect.

Machining centers are usually classified by the relative position of the spindle and the worktable, and are divided into horizontal, vertical and universal machining centers.

(1) Horizontal machining center: refers to the machining center in which the axis of the spindle is parallel to the worktable, and is mainly suitable for machining box parts.

(2) Vertical machining center: It refers to the machining center with the axis of the main shaft and the worktable set vertically, mainly suitable for processing complex parts such as plates, discs, molds and small shells.

(3) Universal machining center (also known as multi-axis linkage machining center): It refers to a machining center that can control the linkage change through the angle between the machining spindle axis and the rotation axis of the worktable, and complete the machining of complex spatial surfaces. It is suitable for the machining of impeller rotors, molds, cutting tools and other workpieces with complex spatial curved surfaces.

Whether it is used for machining centers or data-controlled lathes, the tools and suction cups used for machining workpieces are very important. With the continuous rapid development of the industrial field, many machining centers and CNC machine tools use magnetic suction cups with electro-permanent permanent magnets as The tooling fixture can prolong the service life of the tool, connect to the numerical control system, and improve the precision of the workpiece.
