2DIJET Industrial Co., Ltd.
Possible to high precision and high efficient machining for aluminum, stainless steel and titanium alloy in aerospace tooling.
Adopting high precision design enabled minimum deflection and high accurate machining True 90 degrees shoulder milling Multi-purpose milling is possible: face milling, shoulder milling, slotting, ramping and helical interpolation Insert has key for high velocity revolution specification Internal coolant supply Adopted “G-body” High metal removal rate: Q=2,250cc/min by 50 dia.(aluminum alloy)
