This broaching machine is a special broaching machine developed for machining of sliding vane grooves of air compressors, and a special double-station pull-up broaching machine that can broach two workpieces at a time with high production efficiency. Deep sliding vane grooves need be machined at high accuracy, so the traditional machining process of milling before grinding leads to high machining cost. This broaching machine can broach for forming at a time so as to improve the work efficiency significantly.
