The materials commonly used in turning machines are free cutting steel and copper.The steel for free cutting contains sulfur S and materials with higher phosphorus content. Sulfur and manganese are present in the form of manganese sulfide in steel. Manganese sulfide is used in modern lathes. Aluminium alloys are used for materials used for processing. The density of aluminum alloys is greatly reduced with respect to the density of iron and steel materials, and lathes are difficult to process, have high plasticity, and the weight of products is greatly reduced, which also greatly shortens the time required to machine lathe parts. What followed was a reduction in costs that made aluminum alloys a favorite among aerospace accessories.
Advantage:
1, easy to ensure the accuracy of the workpiece surface processing; processing, the workpiece around a fixed axis of rotation, each surface has the same axis of rotation, it is easy to ensure the coaxiality between the processing requirements;
2, the cutting process is relatively stable; in addition to the intermittent surface, the lathe machining process is continuous in general, unlike milling and planing, in the course of a pass, the cutting teeth have multiple cuts in and out, resulting in Impact
3, for the finishing of non-ferrous metal parts; some non-ferrous metal parts, due to the lower hardness of the material itself, good plasticity, with other processing methods is difficult to get a smooth surface;
4, the tool is simple; turning tool is the most simple kind of tool, manufacturing, sharpening and installation are very convenient, which facilitates the selection of a reasonable angle according to the specific processing requirements.
