What is the difference between the so-called fine car and rough car?
Fine car is the processing process in the finishing process, the need to ensure that the product size tolerance, row tolerance surface roughness of the corresponding requirements.
Rough car can achieve the processing accuracy of IT12 ~ ITll, surface roughness Ra 50 ~ 12.5μm.
Roughing is mainly to remove most of the machined surface of the machined surface, in the allowable range should try to choose a large depth of cutting and feed.
Is the processing of rough processing processes, mainly the workpiece surface of the excess material cutting, the general size of the product,
