Filed: 1998-10-09
Abstract: PROBLEM TO BE SOLVED: To cut a material hard to be cut at high speed by forming a front rake and a cutting face length of an end mill or a drill cutter having a blade part coated with a diamond coating layer within a prescribed value range. SOLUTION: In an end mill or a drill for a high-speed rotation cutting tool, a front rake E is set to not less than -10 deg. and not more than -60 deg. and its cutting face length F is set to one time or more of the cutting depth for changing a positive rake into a negative rake to be used. The cutting depth is always smaller than the negative cutting face length F so that the cutting starts from a line segment GH on the cutting face and ends at a point G. It is so considered that this fact brings about a different effect from that of the positive rake in discharge of cutting chip. A material hard to be cut such as high silicone aluminium alloy can be cut at high speed, at least approximately 200 m/min or more, in short, approximately 2000 m/min without increasing the cutting resistance and with improving the cutting work roughness.
