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.

For High Efficiency Deep Grinding (HEDG) using CBN wheels with large depths of cut and fast workspeeds, preheated material ahead of the grinding zone is removed together with the chips, thereby lowering the temperature on the finished surface. Analytical models have been developed which take all of these effects into account.

Bernoulli's energy equation is a square law. Therefore, at a pressure of 1,000 psi, the nozzle will flow half of 6 gpm, or 3 gpm, at 4,000 psi, sufficient for a 1"-wide (25.4mm) grinding wheel. For the 40° fan to cover a 1"-wide wheel, the tip of the nozzle should be at least 1.4" (35.6mm) from the wheel surface.

The straight wheel is the most common mode of a wheel that is found on pedestal or bench grinders. This is the one widely used for centreless & cylindrical surface grinding operations. As it is used only on the periphery, it forms a little concave surface on the piece. This is used to gain on several tools like chisels.

This means that grinding wheels used on stainless steel must be nearly free (less than 0.1%) of iron, sulfur, and chlorine. Grinding wheels on their own don't grind; they need a power tool. Anyone can tout the benefits of an abrasive wheel or a power tool, but the reality is that power tools and their grinding wheels work as a system.
