The main components of the lathe are: headstock, exchange gearbox, feed box, slide box, tool holder, tailstock, light bar, lead screw, bed, foot and cooling device. Headstock: Also known as the headstock, its main task is to pass the rotary motion from the main motor through a series of shifting mechanisms to make the spindle get the required rotation speed of the two types of forward and reverse steering, while the spindle box separates part of the power. Transfer the movement to the feed box. The main shaft of the headstock is a key part of the lathe. The smoothness of the spindle running on the bearing directly affects the machining quality of the workpiece. Once the rotation accuracy of the spindle is reduced, the use value of the machine tool is reduced.

CNC machine tool is a kind of mechatronics processing equipment that controls the machine tool to automatically process according to the given motion trajectory through digital information. After half a century of development, CNC machine tools have become one of the important signs of modern manufacturing. In China’s manufacturing industry, the application of CNC machine tools is more and more extensive, which is the embodiment of a company’s comprehensive strength. CNC lathe is the abbreviation of digital program control lathe. It combines the characteristics of universal versatile lathe, precision lathe with high processing precision and special lathe with high processing efficiency. It is the largest in domestic use and the most widely covered. A CNC machine tool. CNC lathes can be divided into two categories: horizontal and vertical. Horizontal lathes are available in both horizontal and inclined rails. High-grade CNC sleepers generally use inclined rails. According to the number of tool holders, it can be divided into single tool holder CNC lathe and double tool holder CNC. The former is two-coordinate control and the latter is 4-coordinate control. Most of the CNC lathes are equipped with inclined rails.
