4. Grind large quantities. Centerless grinding can essentially be used in working any size workpiece. Tools like gravity chutes, hopper feeders and magazines are used to adapt the mechanism to different part sizes. 5. Longer yield/ wheel life. Because there is no need for centering, no external feeding mechanism is needed.

2020-10-19 Perhaps the most major factor in centerless grinding is the choice of grinding wheel. It must be suited to both the metal from which the parts are made and the surface finish required. In addition to being available in different diameters and widths/thicknesses, grinding wheels come in different grain types and grit sizes, often using super

2021-2-23 A centerless grinding machine is accurate, simple, and productive; in through-feed centerless grinding of bushes or pins, with a good work-piece feeding system, the work-pieces simply follow each other, enter the grinder, and comes out ground continuously. The machine eliminates the time wasted on clamping and de-clamping the workpiece.
