In hardware processing, any rotating parts that can be clamped on a regular lathe can be processed on a CNC lathe. However, CNC lathes have the characteristics of high machining accuracy, the ability to perform linear and circular interpolation, and the ability to automatically change gears during hardware processing. Their process boundaries are much wider than ordinary machine tools.

CNC lathes have good rigidity, high manufacturing and tool setting accuracy, and can easily and accurately enter manual and automatic compensation. Therefore, they can process parts with high dimensional accuracy requirements. The tool activities of other CNC turning are completed through high-precision interpolation activities and servo drives. In addition, the machine tool has good rigidity and high manufacturing accuracy, so it can process parts with high precision requirements for forms such as straightness, roundness, and cylindricity of the generatrix. Regarding the appearance of arcs and other curves, the machining form and the geometric form required on the drawing are much closer to the level than using a copying lathe.

CNC lathes have constant linear speed cutting performance, so it is advisable to choose the optimal linear speed to cut the cone and end face, so that the surface roughness value after turning is both small and uniform, and to process parts with small and average surface roughness values.

CNC lathes are not only capable of turning straight, tapered, and end face threads with equal lead lengths, but also capable of turning threads with smooth transitions between variable lead lengths. When turning threads on a CNC lathe, the spindle does not need to take turns like a regular lathe. It can cycle one tool after another without stopping until the end, so the efficiency of CNC lathe threads is very high.
