TungMeister – 2 Wheel Crank Shaft – AH735
IMPROVED PRODUCTIVITY AND TOOL LIFE
For the crescent key machining of motorcycle crankshafts, the conventional tool used was a 12-flute T-slot cutter, but chatter was a significant issue.
To improve chatter resistance, we proposed using the TungMeister T-slot head. By reducing the number of cutting edges from 12 to 6, we were able to suppress chatter.
As a result, we achieved a 9 times productivity and 3 times longer tool life.
