"Centreless grinders" are used primarily for round work pieces (e.g. round steel bars and pipes) which are moved past one, but mostly several, grinding head(s) (grinding station(s)) while rotating. Pre-grinding, intermediate grinding and finishing on centreless grinders are mostly performed wet.
The abrasive tools used are agglomerate (long-life) abrasive belts.
As they are supported at several points, the work pieces are not subjected to any major flexural and torsional stress. This makes it possible to grind even thin-walled pipes and short work pieces as well as work pieces of nearly endless length with perfect ease. When used in combination with long-life abrasive belts, these grinders allow the user to grind an exceptionally high number of running metres of the material to be processed with a consistent surface finish.
