Machining with coolant is recommended for Ni-base heat-resistant alloys and titanium alloys. ★: 1st Recommendation ✩: 2nd Recommendation The bold-faced number indicates a center value of recommended cutting condition. Adjust the cutting speed and the feed rate within the above conditions according to the actual machining situation. Internal coolant is recommended for slotting.
