Top 10 centerless grinding machine Manufacturers in the world 2026

Introduction to Centerless Grinding Machine

A centerless grinding machine is a type of grinding equipment used to produce cylindrical workpieces without the need for the workpiece to be centered on its axis. It consists of a grinding wheel, a regulating wheel, and a work - rest blade. The grinding wheel performs the actual grinding operation, removing material from the workpiece. The regulating wheel controls the rotational speed and feed rate of the workpiece, while the work - rest blade supports the workpiece during the grinding process. Centerless grinding machines are widely used in various industries, such as automotive, aerospace, and manufacturing, due to their high precision, efficiency, and ability to handle a large volume of workpieces.
