In specific use, the larger the angle of the chip groove 12, the more conducive it is to chip removal.

同一排屑槽12处，所述刀身切削刃设置在排屑槽12一侧面的侧边缘处，端部切削刃13设置在排屑槽12两侧面的前端边缘处。如图2所示。At the same chip groove 12, the blade cutting edge is arranged at the side edge of one side of the chip groove 12, and the end cutting edge 13 is arranged at the front end edge of both sides of the chip groove 12. As shown in FIG.

进一步的，两对端部切削刃13中，有一对端部切削刃13中的两条端部切削刃13被另一对端部切削刃13分隔开；未被分隔开的那对端部切削刃13中，两条端部切削刃13相互平行，使它们间的间隔构成端部排屑槽14。由于端部排屑槽14的存在，能够方便刀具铣槽。Furthermore, in one of the two pairs of end cutting edges 13, two end cutting edges 13 in one pair of end cutting edges 13 are separated by the other pair of end cutting edges 13; in the pair of end cutting edges 13 that are not separated, the two end cutting edges 13 are parallel to each other, so that the interval between them forms an end chip groove 14. Due to the existence of the end chip groove 14, it is convenient for the tool to mill the groove.

刀具在具体制造时，切削刃和端部切削刃13可以是单独焊接在排屑槽12侧边缘和切削段三前端面上的刀片，该刀片具有一定的宽度和厚度，如图4所示，端部切削刃13的宽度为2mm；或切削刃和端部切削刃13也可以是刀身通过打磨，磨出来的可以用于切削的部分。When the tool is manufactured, the cutting edge and the end cutting edge 13 can be blades separately welded on the side edge of the chip groove 12 and the front end surface of the cutting segment 3. The blade has a certain width and thickness. As shown in Figure 4, the width of the end cutting edge 13 is 2mm; or the cutting edge and the end cutting edge 13 can also be the part of the blade that is ground out by grinding.
