Adjust the cutting speed and the feed rate : 1st recommendation : 2nd recommendation within the above conditions according to the actual machining situation. Cutting with coolant is recommended for ni-base heat resistant alloy and titanium alloy. Cutting with coolant is recommended to get good finished surface. M77 Chipbreaker Milling
