1, CNC lathe rough turning, machine tool low speed, large feed.
2, CNC lathe finishing, high machine speed, small feed.
The specific processing steps, machine tool speed and feed speed should be determined according to the shape and clamping mode of the parts. The emphasis is on rough turning, with large feed, large force and large material deformation. It is recommended to choose low speed. In finishing, in order to ensure the tolerance of parts within an acceptable range, we can only reduce the feed, stress and material deformation, and at the same time choose high speed to ensure surface roughness.
