Centerless Grinding Wheel

Centerless grinding wheel is a grinding wheel installed on the centerless grinding machine. It interacts with the guide wheel and the pallet to form a grinding method.

Centerless grinding method is composed of three mechanisms: a grinding wheel, an adjusting wheel and a workpiece holder (carrier). The grinding wheel actually performs the grinding work, the adjusting wheel controls the rotation of the workpiece, and the workpiece enters the cutting speed. As for the workpiece support to support the workpiece during grinding, there are several ways to match the three parts, except for stopping the grinding, in principle, the same.

The workpiece to be processed is supported by the pallet, and the guide wheel is oriented to the pallet. When the circular motion is used to drive the workpiece to rotate, it is ground by the centerless grinding wheel. When the workpiece is ground, the surface quality is high and the precision is relatively high. In the grinding, the grinding wheel size is also very important. The coarse-grained centerless grinding wheel is often used for coarse grinding. Grinding processing can only process workpieces that are not required to be high. Generally, in order to speed up the grinding speed during machining, this method is used for the first processing of workpieces with large processing volume, which is due to its relatively fast processing speed, but the workpiece has a low finish. The quality of the workpiece processed by the fine-grained centerless grinding wheel is reversed, and the processing speed is slightly slower, but the finished workpiece has a high finish. If the selected particle size is suitable, the mirror effect can be achieved. Therefore, the selection of the centerless grinding wheel is based on the workpiece. Technical process requirements are specifically selected. It also includes the hardness, tissue density, and particle size of the grinding wheel. Grinding different workpieces, the choice of cutting fluid is also different. For ordinary iron, we only need ordinary cutting fluid, and when we burn aluminum soft parts, we need kerosene to cut cold.

In centerless grinding, the workpiece is held between two wheels, rotating in the same direction at different speeds, and a workholding platform. One wheel, known as the grinding wheel (stationary wheel in the diagram), is on a fixed axis and rotates such that the force applied to the workpiece is directed downward, against the workholding platform. This wheel usually performs the grinding action by having a higher tangential speed than the workpiece at the point of contact. The other wheel, known as the regulating wheel (moving wheel in the diagram), is movable. This wheel is positioned to apply lateral pressure to the workpiece, and usually has either a very rough or rubber-bonded abrasive to trap the workpiece.

Product Working Diagram：

The speed of the two wheels relative to each other provides the grinding action and determines the rate at which material is removed from the workpiece. During operation the workpiece turns with the regulating wheel, with the same linear velocity at the point of contact and (ideally) no slipping. The grinding wheel turns faster, slipping past the surface of the workpiece at the point of contact and removing chips of material as it passes.
