Stock removal

Stock removal describes the amount of material that is removed from a workpiece over the entire service life of an abrasive. It is often referred to as “stock removal rate” or “total stock removal” and shows how quickly and effectively an abrasive works.

High stock removal means that a large amount of material is removed in a short time. This is especially important when pre-grinding, deburring or removing weld seams.
Insufficient stock removal increases machining time and costs.

What effect does stock removal rate have on the surface?
Coarse grit sizes remove a large amount of material, while fine grit sizes remove less, but yield a finer surface.

Typical problems when stock removal is no longer correct:

• The wrong grit size or abrasive was selected for the material to be machined.
• The abrasive is worn out, glazed or clogged.

What do you need to keep in mind about stock removal?

• Select a grit size suitable for the task (coarse for high stock removal, fine for achieving a defined surface).
• Make sure that the combination of grain, bond and backing is correct.
• Use modern abrasives with self-sharpening grain to achieve consistently high stock removal. The VSM CERAMICS and ACTIROX series are ideal for this.
