苏联马格列夫斯基建筑机械厂研制了几种新型铣刀。一、带锥柄的组合式键槽铣刀铣刀结构如图1所示,端部有一个正方形槽,槽内装有Γ形切削刀头1和7。刀头7的凸缘顶着刀头1的端面,刀头1用圆柱销6和刀体2相连。刀头由楔块4紧固,楔块的分力传给刀头7的端部,然后经凸缘传给刀头1的端部。刀头1在其圆柱销6的作用下,挤压刀头7的前面,并使之向槽壁
The Soviet Union Maglevsky Construction Machinery Factory has developed several new cutter. A combined keyway milling cutter with taper shank As shown in Figure 1, the end has a square groove, Γ-shaped cutting head with 1 and 7. The flange of the cutter head 7 bears against the end face of the cutter head 1, and the cutter head 1 is connected with the cutter body 2 by the cylindrical pin 6. The cutter head is fastened by a wedge 4, and the component force of the wedge is transmitted to the end of the cutter head 7 and then to the end of the cutter head 1 via the flange. The cutter head 1 presses the front face of the cutter head 7 with its cylindrical pin 6 and brings it toward the groove wall
