In centerless grinding, the workpiece is held between two grinding wheels, rotating in the same direction at different speeds.One grinding wheel is on a fixed axis and rotates so that the force applied to the workpiece is directed downward. This wheel usually performs the grinding action by having a higher linear speed than the workpiece at the point of contact.

Re: kwik way vs. centerless valve grinder. The comec is a good machine for accuracy....only if the valve stem does not have any ovality where it runs on the roller blocks.it is slower to face valves due to not being able to load up the job as much as it relies on the roller to push the valve back into the chuck.with that in mind u can also face ...
