详细介绍
键槽拉床本机床用途以及特点：
本机床是针对单键槽齿轮、齿圈、空调压缩机缸体滑片槽加工而研发的类机床，机床采用双油缸上拉式内拉床为基础，设计夹具，工位数可以在1-3个选择，生产效率高。对比传统的先铣后磨的加工工艺，本机床采用一次拉削成型，精度高、效率高，可以大幅提升工作效率，降低加工成本。
Applications and Advantages:
It is a special broaching machine designed for single keyway gears, geared rings, and vane groove in cylinder block of air conditioning compressor. This machine is designed on the basis of twin cylinder table-up internal broaching machine, providing with special designed fixtures. It also features greater production efficiency as 1 - 3 broaching station(s) is optional. Compared with the traditional process technology (milling before grinding), this machine can complete one-time-forming of the keyway with high precision, which greatly increase production efficiency and reduce cost.
