TungMeister – Crank Shaft – AH715


The conventional product used a solid T-slot cutter, but the occurrence of chatter was a problem. To eliminate chatter, we proposed the TungMeister T-slot tool.
By increasing the shank diameter from the conventional Φ6 to Φ20, we achieved approximately 19 times greater tool rigidity.
The TungMeister T-slot tool suppressed the occurrence of chatter and contributed to improved machining stability.
