高速拉削是拉削工艺方面的一项新成就,它有如下特点:1.生产效率高,被加工槽一次拉削成型,拉削速度可达200英尺/分,生产效率比普通拉削提高8～9倍。2.采用组装拉刀,粗拉阶段与精拉阶段不需要更换刀具,刀具制造容易标准化、寿命长。如采用齿上带有分屑槽的拉刀对盘的榫槽进行拉削,试验结果:精拉刀平均可以加工30个盘;粗拉刀平均可加工600个盘。3.拉削过程自动化,工人只需装卸零件,减轻了工人体 High-speed broaching is a new achievement in broaching technology. It has the following features: 1. High production efficiency. It can be broached once by the processing slot. The broaching speed can reach 200 feet per minute. The production efficiency is higher than ordinary broaching 8 ~ 9 times. 2. The use of assembly broaches, rough-pull stage and the stage does not need to change the tool, the tool is easy to standardize manufacturing, long life. Such as the use of broaching teeth with a broach broach on the tongue and groove of the plate, the test results: fine broach can process an average of 30 plates; rough broach can process an average of 600 discs. 3. Broaching process automation, workers simply loading and unloading parts, reducing the worker body
