The main advantage of Keyseating is in the fact that it offers maximum flexibility for largely specialized keyways. This process is then repeated until there is a cut deep enough to satisfy the specifications required for its application. This subtle movement makes it possible for every stroke to remove a little more material. Here’s how it works, The Keyseater cutter moves slowly outward at every cut. Some keys have only one cutting tool, while other machines (such as the Davis Keyseater) use a multi-cutter to make cutting speeds as fast as broaching.

This is done by cutting the keyway with a key-operated device which removes the material through a series of tooth-cutting movements.

How are keyed shafts cut? Find below the process involved in keyed shaft cutting. The most common key components are pulleys, gears, clutches, and washers. Keyed shafts allow relative axial movements between the parts involved. The entire system is known as a keyed shaft or joint hinge. For a key to work, the shaft and the rotating member of the machine must have a keyseat and a keyway, which are a slot and a pocket in which the key can fit into.

The key, therefore, prevents the relative rotation between these two parts and may allow torque transfer.

In the field of engineering (mechanical), a key is an element of the machine that connects a rotating element to a nearby shaft.
