苏联内燃机车制造工厂采用了一种齿轮齿沟粗切铁刀(见图)。铣刀体由用螺钉4紧固于体3的刀头接盘1、2组成。在刀头接盘组装后钻孔,用销钉5固定。在体内嵌入20把装有T5K10硬质合金的刀头。一个刀体内装有四种具有特种断面的刀头。这样就能一次极其近似地铣出两个齿沟。将铣刀体上的刀头安装在刀杆上,并用千分表按刀尖检验。同时,刀头成对安装成棋盘状排列,其高度差为0.2毫米。因为在安装时刀头不能在横向调整,所以在刃磨时必须保证所有刀头的外形相同。安装时刀头用两个螺钉和
Soviet Union diesel locomotive manufacturing plant uses a gear trough rough cut iron knife (see photo). The cutter body consists of a cutter head adapter 1, 2 fastened to the body 3 with a screw 4. Drill holes in the cutter head assembly and then fix with pin 5. Embedded in the body 20 with T5K10 carbide head. There are four kinds of cutter head with special section in one cutter body. In this way, two trenches can be milled in a very close approximation. The cutter body on the cutter head mounted on the arbor, and use a pointer to check the tip. At the same time, the blade head mounted in pairs arranged in chessboard, the height difference of 0.2 mm. Because the cutter head can not be adjusted in the horizontal direction during installation, the sharpening must ensure that all cutter heads have the same shape. When installing the cutter head with two screws
