Thread Milling Model
Alloy718
MMTM / M-Thread Mill

Work size: 56×36×46(mm)

Material: Alloy718(Equivalent Inconel®718)
Cutting Time: 18 sec per thread

Sample of machining super heat-resistance alloy with the MMTM reduced cutting deflection remarkably compare to taps. By the blade shape that attached great importance to the sharpness, machining precision improved. MUGEN-COATING realized to prolong tool life.

Comment

MMTM can cut super heat-resistance alloy stably which was difficult with conventional type of tap.
