In the mechanical industry, the connection of keys is visible everywhere. The processing of keyways is often encountered. Generally, the grinding grooves on the shaft are mostly milled. The most common machining method for the keyway on the hub is cutting, and of course, high-efficiency production methods, such as broaching, which require special equipment and tools. However, for small factories, there is no special equipment, that is, there is no ordinary insertion machine, and it is difficult to process the keyway. When encountering the machining keyway, it used to be broaching with a single knife on the lathe. The amount of one-time feed is very small. It takes a long time to broach a keyway, and there is also a knife-carrying phenomenon, so that the quality of the keyway is not good. To guarantee.
