If you want to process a large number of small cylindrical parts, a centerless grinder is a machine you need. Because the grinder does not require you to reset every part. Even if you need to machine parts with different diameters, don't worry-the centerless grinder can handle multiple diameters with just a few changes.

Centerless grinding requires no such workholding methods. Parts are fed between a grinding wheel and a smaller regulating wheel while resting on an angled workpiece support—a blade-like device that sits between the opposing wheels. Schematic of a horizontal centerless grinding setup. Illustration by CTE staff.

Centerless grinding requires that both the workpiece and the grinding wheel rotate. chip: A small piece of material that is removed from a workpiece. Chips are formed when a tool cuts or grinds a material. circumference: The boundary or perimeter around a circle. Circumference measures the distance around a circle.

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 ...

Unlike center-type or chucker-type grinding, parts made using a centerless process do not require center holes, drivers or workhead fixtures. Instead, the workpiece is supported on its own outer diameter by a workblade located between a high speed grinding wheel and a slower speed regulating wheel with a smaller diameter.

Centerless Basics A centerless grinder has three main components: a grinding wheel, a regulat-ing wheel and a work support blade. Be-cause the entire workpiece is supported by the regulating wheel and the blade, centerless grinding provides a more rigid system, enabling more efficient and ac-curate grinding compared to grinding between centers.

In centerless grinding, the workpiece rotates between a grinding wheel and a regulating drive wheel. The work is supported from below by a fixed work-rest blade. The two basic modes of centerless grinding are "thru-feed" and "in-feed" or "plunge" mode. In the thru-feed mode, the work proceeds in the axial direction through the slowly narrowing ...
