Through–feed centerless grinding is completely feeding the workpiece to the grinding wheels. This doesn't require a separate speed mechanism, making it very efficient yet it can only be used for cylindrical–shaped parts. The wheel cannot be dressed to create more complex shapes since this only imparts a horizontal velocity to the workpiece.

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.

Centerless grinding is a machining process that uses abrasive cutting to remove material from a workpiece. Centerless grinding differs from centered grinding operations in that no spindle or fixture is used to locate and secure the workpiece; the workpiece is secured between two rotary grinding wheels, and the speed of their rotation relative to each other determines the rate at which material ...

This is critical to the roundness and diameter tolerances of the bar. Both wheels rotate. The regulating wheel is slanted up a little from the horizontal. As it turns, it pulls the bar past the grinding wheel, so no external feeding mechanism is required.
