我厂某产品镗盲孔φ100~(+0.07)毫米(如图)工序,原用高速钢扁钻刀具,切削中刀刃容易烧伤,每加工3～5件产品就须刃磨刀具一次,刀具耐用度低,一把刀的寿命只能加工50件产品,高速钢浪费量大。现使用我们试验成功的重磨式机夹扩孔钻(见图),断屑好,寿命长,加工辅助时间减少,提高了生产效率,节约了高速钢材料,较好的发挥了组合机床作用。重磨机夹扩孔钻结构简单、夹紧牢固,采用楔块夹紧,刀槽定位、更换刀片方便,可多
I plant a product boring blind hole φ100 ~ (+0.07) mm (pictured) process, the original high-speed steel flat drill tool, the cutting edge easy to burn, each processing 3 to 5 products must sharpen the knife once, the tool durable Low degree, the life of a knife can only process 50 products, high-speed steel waste large. Now using our successful trial re-grinding machine reaming drill (see photo), good chip breaking, long life, processing aids to reduce the time, improve production efficiency and save high-speed steel materials, the better play a combination of machine tool . Re-grinding machine folder reaming drill simple structure, firm clamping, the use of wedge clamping, knife slot positioning, easy to replace the blade, can be more
