TungMeister – Motor Shaft – AH725

IMPROVED PRODUCTIVITY

The high-speed steel (HSS) center drill currently used for center drilling of motor shafts, a type of automotive part, has been resulting in slow machining times.
For a newly launched motor shaft, TungMeister was proposed and tested.
By increasing the cutting speed and feed rate, a 4.7 times improvement in machining efficiency was achieved, successfully addressing the challenge of reducing machining time.
