我厂加工的机壳吊攀平面如图1所示,过去一直采用把钻头前面磨平的方法来加工.这样加工出来的平面往往达不到规定的要求,而且生产效率低.现在我们设计了一种新型的节能锪刀,可在一次加工中完成钻孔,锪平两个工序其结构如图2所示.它由刀体1,固定螺钉2、5刀片3等构成.在刀体1柄部采用与Z512K钻床连接的短圆锥D4结构,在前部铣有两个左右相对与刀片同宽的槽,而刀片是利用铁刀盘替换下 I plant the processing of the plane crane hanging plane shown in Figure 1, the past has been used to smooth the front of the drill bit processing. This plane out of the process often fail to meet the requirements, and the production efficiency is low. Now we designed A new type of energy-saving trowel can be completed in a single drilling process, the level of two processes its structure shown in Figure 2. It consists of a knife body 1, 2 and 3 fixed screws, etc. In the body 1 Handle with Z512K drilling machine connected to the short cone D4 structure, in the front milling with two relative to the width of the blade with the blade, and the blade is replaced with iron cutter disc
