这种端铣刀(苏联发明证书№729007)的结构如图所示:1为开有若干个槽的刀体,在每个槽中利用楔铁2固装着一叠刀杆3,这些刀杆上都焊有硬质合金刀片4。在和刀杆相接触的楔铁面上开有二个楔形齿,而刀杆面是个斜面。当压入楔铁时,楔铁的二个齿扎入刀杆3里,因而同时使这几把刀可靠地固定。成叠的刀的数量依所需要的铣削深度来决定。刀杆后半部的厚度做得比刀头部的厚度大,而在刀体上相邻接的槽中的每一叠刀都是相互交错配置的。因而,一叠
This end mill (Soviet invention certificate № 729007) the structure shown in the figure: 1 is open a number of slots in the body, in each slot using wedge iron 2 fixed a stack of arbor 3, the arbor Welded carbide inserts on the 4. There are two wedge-shaped teeth on the wedge iron surface that is in contact with the arbor, and the arbor surface is a bevel. When the wedge iron is pressed in, the two teeth of the wedge iron penetrate into the arbor 3, thereby simultaneously securing the several knives securely. The number of stacks of knives depends on the milling depth required. The thickness of the rear half of the arbor is made thicker than the thickness of the bit portion, and each of the stacks adjacent to each other in the body is staggered. Thus, a stack
