Centerless grinding: unique processing method

Today, let's talk about another grinding method: centerless grinding. The reason why this grinding method is called centerless grinding is because the workpiece does not need to determine the center hole during the grinding process. This is also the biggest difference with other grinding processing. In the process of centerless grinding, two wheels are needed, one is a centerless grinding wheel and the other is a rubber guide wheel. The guide wheel grinds the workpiece by driving the cylindrical workpiece to rotate on the cushion iron. The processing object of centerless grinding is mainly cylindrical products.

Centerless grinding has many advantages, which make it widely used in industrial production.

​

High accuracy: Because centerless grinding does not require a center hole, there will be no impact on the accuracy of the center hole deviation, so that the workpiece after grinding has a higher accuracy.

Good surface quality: During centerless grinding, there are fewer grinding marks on the surface of the workpiece, and better surface quality can be obtained.

​

High production efficiency: centerless grinding can grind multiple workpieces at the same time, making the production efficiency greatly improved.

Energy saving: Since centerless grinding does not require a center hole, many unnecessary operating steps can be reduced, thereby saving energy.

In centerless grinding, centerless grinding wheel and rubber guide wheel are very important.

Centerless grinding wheel is mainly used for grinding workpiece. Its design can be adjusted for different workpiece materials and grinding requirements to achieve efficient grinding results. Like other types of grinding wheels, the selection of centerless grinding wheels is still based on the material characteristics of the workpiece to be processed, select the corresponding abrasive and formula.

Therefore, the centerless grinding wheel can be corundum and silicon carbide in the general grinding wheel, or diamond and CBN in the super-hard grinding wheel.

The rubber guide wheel mainly plays the role of guiding and positioning in centerless grinding. It makes contact with the workpiece, drives the workpiece into the grinding area, and controls the rotating motion of the workpiece, so that the workpiece can be correctly ground in the required position. In addition, the rubber guide wheel can also absorb vibration and shock during grinding, improving the precision and efficiency of grinding.

In short, centerless grinding is a unique and efficient grinding method, which has been widely used in industrial production. Because of its high precision, high quality, high efficiency and energy saving advantages, centerless grinding has become an indispensable part of modern manufacturing. By understanding the working principle, characteristics and advantages of centerless grinding, as well as the role of centerless grinding wheels and rubber guides in the centerless grinding process, we can better understand this processing method and bring more possibilities to industrial production.
