“机械工人”(冷加工)57年第8期介绍了“加工镶齿铣刀镶刀槽的插刀”。这种插刀我们过去是用高速钢做成整体的,它有两个缺点:1)当刃部磨损到不能再重磨的时候,整个插刀就报废了,高速钢浪费很大;2)重磨后,不容易对刀。我厂工具车间周世清老师傅根据上面两个缺点作了改进。现在介绍一下改进的情况。周师傅把原来的整体插刀改为组合的插刀;组合插刀由刀杆1、连接体2、蝶钉3、插刀4组成。改进后的优点是:1)市约刀杆材料,并增强了插刀的刚性;2)插刀磨损后只要松开螺钉3),取下插刀4重磨,磨好后再装上去,不必进行对刀。图2是
“Machinist” (Cold Working) No. 57, 2007, introduced the “Insert tool for machining insert cutter insert groove”. The knife we used to be made of high-speed steel in the past, it has two shortcomings: 1) When the blade worn to no longer regrind, the entire knife is scrapped, high-speed steel wasted; 2) After grinding, not easy to knife. Zhou Weiming, our factory tool shop, made improvements based on the above two shortcomings. Now introduce the situation of improvement. Zhou master to the original overall knife into a combination of knife; combination knife by the knife 1, connector 2, butterfly nail 3, knife 4 components. Improved advantages are: 1) city about the bar material, and enhance the rigidity of the knife; 2) as long as the knife is loosened after loosening the screw 3), remove the knife 4 re-grinding, grinding and then loaded up, Do not have to knife.
