Through-feed centerless grinding

Abrasive treatment where a shaft is ground between two rollers until the diameter allows it to pass.

The process

The workpiece in the form of a shaft is fed via a support blade [1] centered between two rolls. The distance between the rollers is slightly smaller than the diameter of the workpiece. One roll is the grinding tool [2] and the second roller [3] regulates the rotation of the workpiece. The rollers are slightly tilted allowing the workpiece to be slowly moved axially along the support blade so that no feeding mechanism, or fixture is required. Process is usually supported by a cutting fluid for cooling and removal of the chips formed. High purity is important to not affect the grinding result.

Cutting fluid
Cutting fluid has three main purposes. Cooling, lubrication and removal of chips.
