Roughing and finishing of machining

- Dec 15, 2017 -

In order to ensure the processing accuracy, rough, finishing the best separately. Because roughing, cutting a large amount of cutting force by the workpiece, clamping force, heat and more, and the processing of the surface there is more significant work hardening phenomenon, the workpiece there is a large internal stress, if the rough, roughing Continuously, the precision of the finished part is quickly lost due to the stress redistribution. For some high precision machining parts. After roughing and finishing, cryogenic annealing or aging treatments should also be arranged to eliminate the internal stresses.
