اقرأ أكثرFacing is used for machining a large flat area, typically the top of the part in preparation for other milling operations. A face mill is a solid body that holds multiple carbide inserts that can be replaced as they wear out. The more inserts, the faster the metal removal rate. Cutters with a 45 lead angle are used most frequently.
