The materials usually processed by lathes are free-cutting steel and copper. Free-cutting steel contains high sulfur S and phosphorus P. Sulfur and manganese exist in the form of manganese sulfide in steel, while manganese sulfide is in steel. Plays the role of lubrication, making the steel easier to cut, thereby improving the production schedule of the lathe.

CNC lathe processing features:

1. The cutting process is relatively stable; in addition to the intermittent surface, the lathe machining process is generally continuous, unlike milling and planing, in the process of one pass, the cutter teeth have multiple cuts in and cut out, resulting in Impact;

2. It is suitable for the finishing of non-ferrous metal parts; some non-ferrous metal parts, because the hardness of the material itself is low, and the plasticity is better, it is difficult to get a smooth surface with other processing methods;

3. The tool is simple; the turning tool is the simplest one of the tools. It is easy to manufacture, sharpen and install, which is convenient for selecting a reasonable angle according to the specific processing requirements.
