一、端铣刀的崩刃现象机夹可转位(不重磨)刀片的高速端铣刀,在生产中已比较普遍得到推广和应用,但是,由于端铣刀刀齿切入工件接触瞬间的冲击状态没有被人们所掌握,结果造成可转位刀片大量产生崩刃现象。众所周知,为了减少端铣刀的崩刃现象,希望端铣刀的刀齿前刀面与工件的开始接触点在 U 点(端铣工具钢、合金钢等),或 T 点(端铣碳钢或灰铸铁等),而不希望在 S 点或 V 点附近,见附图右下面,刀尖在 First, the phenomenon of end milling chipping Blades can be indexable (non-re-grinding) blade high-speed end mill, in production has been more widespread promotion and application, however, due to the end mill cutter into the workpiece contact moment The impact of the state has not been mastered, resulting in a large number of indexable blade chipping phenomenon. As we all know, in order to reduce the end cutter chipping phenomenon, we hope that the end face of the cutter and the workpiece starting point of contact at the point U (end milling tool steel, alloy steel, etc.), or T point Or gray cast iron, etc.), and do not want in the vicinity of the S point or V point, see the lower right of the drawing, the tip in
