Introduction to Keyway Milling
Keyway milling is a precision machining process used to create keyways in shafts or hubs. A keyway is a narrow slot or groove that runs along the length of a shaft or inside a bore, which is designed to accept a key. The key, in turn, serves as a means of transmitting torque between the shaft and the hub, ensuring a positive connection and preventing relative rotation between the two components. This process is crucial in various industries such as automotive, aerospace, machinery manufacturing, and power transmission, where reliable power transfer and precise motion control are essential.
