TinyTurn – Machine Part – SH730


Excellent cutting edge offers high precision machining for a wide range of internal applications! TinyTurn can machine 2000 pcs/corner without any problem. On the other hand, the competitor starts losing an ideal surface quality due to chipping. The combination of fine edge and smooth coating largely prevents the cutting edge from chipping, providing a beautiful machining surface!
