What are the differences between straight fluted milling cutters and spiral thread cutters?
Straight fluted thread milling cutters for machining small diameter threads.Helical thread milling cutters are used for machining large diameter threads.
It is generally believed that the straight groove and spiral groove chip removal method is different. The former chip is removed and the latter is upward. Follow the straight groove, spiral groove taps a truth.In fact, the spiral groove also has a seismic function. It should be with the cutting surface is always the same number of teeth contact. Straight slots will have gap segments.The groove is stronger than the spiral groove because the groove is not spirally fluted and the depth is deeper.
