Turning
Turning is the cutting process in which the workpiece rotates and the turning tool moves in a straight line or curve in the plane. Turning is generally carried out on a lathe, which is used to process the internal and external cylindrical surfaces, end faces, conical surfaces, forming surfaces and threads of workpieces.
The turning accuracy is generally IT8-IT7, and the surface roughness is 1.6-0.8μm.
1) The rough turning shall adopt large cutting depth and large feed rate to improve the turning efficiency without reducing the cutting speed, but the machining accuracy can only reach IT11 and the surface roughness is Rα20-10μm.
2) High speed and small feed rate and cutting depth shall be adopted as far as possible for semi finish turning and finish turning. The machining accuracy can reach IT10-IT7, and the surface roughness is Rα10-0.16μm.
3) High speed precision turning of nonferrous metal parts with diamond turning tool finely polished on high-precision lathe can make the machining accuracy reach IT7-IT5, and the surface roughness is Rα0.04-0.01μm. This kind of turning is called "mirror turning".
