目前通用粗加工可转位端铣刀,比焊接铣刀切削负荷要小些,它的平均切削深度t和每齿走刀量S_z约为焊接铣刀的一半。若改进可转位铣刀结构,就可以扩大铣刀的应用范围。其中一种趋向是设法提高铣刀夹固部件刚度与强度。图1所示为提高刚性的φ125～200毫米可转位端铣刀,用它加工结构钢时,可增加每齿走刀量。圆头螺钉4把刀片1与刀杆2,同时可靠地从铣刀侧面夹固在刀体3上。由于螺钉的圆头与刀杆前面的半圆形斜槽槽底相互作
The current universal rough indexable end milling cutter, cutting load than the welding cutter to be smaller, and its average depth of cut t and tooth per cutter S_z about half of the welding cutter. If you improve the indexable cutter structure, you can expand the scope of application of the cutter. One of the trends is to try to increase the rigidity and strength of milling cutter clamping parts. Shown in Figure 1 is to improve the rigidity of φ125 ~ 200 mm indexable end mill, steel structure used in it, you can increase the amount of walking each tooth. The round head screw 4 inserts the blade 1 and the arbor 2, and at the same time, reliably clamps the cutter body 3 from the cutter side. Because the round head of the screw interacts with the semicircular chute groove bottom in front of the shank
