Centerless grinding machine is a type of grinding machine that does not require axis positioning of the workpiece for grinding. It mainly consists of three mechanisms: grinding wheel, adjustment wheel, and workpiece support.

Centerless grinding, also known as centerless grinding, is a type of grinding process. There are two grinding wheels, a guide wheel and a grinding wheel. The guide wheel drives the cylindrical workpiece to rotate on the shim, while the grinding wheel plays a grinding role on the workpiece. Centerless grinding belongs to the weekly grinding method.

Principle of Centerless Grinding Machine Grinding

The Centerless Grinding Method is composed of three mechanisms: a grinding wheel, an adjusting wheel, and a workpiece support (bracket). The grinding wheel actually performs the grinding work, the adjusting wheel controls the rotation of the workpiece, and causes the workpiece to have a feed speed. As for the workpiece support, it supports the workpiece during grinding. There are several ways to cooperate with these three mechanisms, except for stopping grinding, and the principle is the same.

Centerless grinding wheel is a type of grinding wheel installed on a centerless grinder, which interacts with a guide wheel and a support plate to form a grinding method. The workpiece being processed is supported by the support plate and driven to rotate by the guide wheel in the direction of the support plate. When grinding the workpiece, the surface quality is high and the accuracy is relatively high. In grinding, the selection of grinding wheel particle size is also quite important. Coarse grained centerless grinding wheels are often used for rough grinding processing, and can only process workpieces with low requirements. Generally, in order to accelerate the grinding speed, this method is used for the first processing of workpieces with large processing volume. This is because of its fast processing speed, but the smoothness of the workpiece is low.

On the other hand, the quality and accuracy of workpieces processed by fine-grained centerless grinding wheels are the opposite. Their processing speed is slightly slower, but the smoothness of the processed workpiece is high. If the appropriate particle size is selected, the mirror effect can be achieved. Therefore, the selection of centerless grinding wheels should be based on the specific technical requirements of the workpiece. This also includes the selection of hardness, tissue density, and particle size of the grinding wheel. Grinding different workpieces requires different cutting fluids. For ordinary iron, we only need ordinary cutting fluid, while for grinding aluminum soft parts, kerosene is needed for cold cutting.

Centerless grinding method

1. Fixed type centerless cylindrical grinder with grinding wheel frame. The grinding wheel frame of this type of centerless grinder is fixed on the bed, and the guide wheel and bracket can be adjusted and moved relative to each other. During through grinding or cut in grinding, the guide wheel, bracket, and workpiece perform feed and compensation movements together.

2. A mobile centerless cylindrical grinder with a grinding wheel frame. The bracket of this type of centerless grinder is fixed on the bed, and the grinding wheel frame and guide wheel frame can be adjusted relative to the bracket. In special cases, feed motion can be performed. The grinding wheel and guide wheel spindle of this type of centerless grinder mostly adopt a double support structure.

3. Tilted centerless cylindrical grinder, in which the center line of the grinding wheel and guide wheel is inclined at an angle of α to the horizontal plane. The bracket is fixed on the bed, and the grinding wheel and guide wheel spindle are double supported structures. The guide wheel frame can be adjusted relative to the bracket, and the grinding wheel frame can perform feed compensation motion.
