[0005] 3. When the length of the guide sleeve is not enough, it will cause the broach to bend upwards or even break when it is working
[0007] However, after the keyway broach is used many times, the keyway broach will be worn out, resulting in the pulled out keyway not meeting the size requirements. Because the keyway broach is more expensive, it needs to be re-grinded, so as to save the cost of the tool the goal of

Description

technical field [0001] The invention relates to a keyway broach grinding device, in particular to a keyway broach grinding machine. Background technique [0002] In the process of keyway processing, small batches of short keyways are usually processed on a milling machine, and if some long keyways and batch keyways are processed on a milling machine, the processing efficiency is extremely low; the keyway broach has high processing efficiency and has the following advantages advantage: [0003] 1. The broaching allowance is large, the number of teeth is large, and when the groove depth is large, it must be drawn in more than two times. [0004] 2. The surface roughness of broaching is relatively large (Ra (2.5~1.25) μm or greater). When the surface roughness is small, a keyway broach with a wiper edge on the side should be used. [0005] 3. If the length of the guide sleeve is not enough, it will cause the broach to bend upwards or even break when it is working. [0006] 4...
