What is finish machining?
Finish machining is designed to improve surface finish, dimensional accuracy and tolerance. Very low feed speed and cutting depth are used for finish machining. Therefore, the cutting rate in finishing is reduced, but the surface quality is improved. Low surface roughness after qualified finishing; therefore, the surface finish is very good. Qualified finishing provides high dimensional accuracy and strict tolerances.
Why uses CNC finish machining?
CNC finishin machining was given for higher accuracy. It can better control the feed speed and cutting depth. In addition, CNC finishin machining can also give better tool control, so that the finishin machining products can be given high dimensional accuracy and close tolerance. In addition, CNC finishin machining could also control the material removal rate (MRR) well. Can effectively avoid causing excessive material loss, unqualified or defective products.
