Processing keyway, with cutting and wire cutting which high precision?
Inserting the folder with the knife debugging more trouble, if the amount of large, then you can do special fixture, processing accuracy is better, if the amount is not recommended with wire cutting.
However, the rough surface roughness of the wire, if the requirements of high, then you can consider using wire walking processing.
Wire cutting is a numerical control equipment, theoretically the processing accuracy is higher than the general slot.
