Factors affecting grinding wheel

Factors affecting grinding wheel

The grinding effect is designed in many aspects, such as grinding efficiency, sharpness, grinding accuracy, finish and grinding wheel life. The following is a detailed analysis of the factors affecting the grinding effect of the grinding wheel from these different dimensions:

2. Sharpness

The sharpness of the grinding wheel affects its cutting ability, which determines the smoothness of grinding and the size of cutting force. The key factors include:

Abrasive type: diamond, cubic boron nitride and other super hard abrasives with high sharpness, suitable for precision grinding of high-hardness workpieces; Traditional alumina and silicon carbide abrasives are suitable for grinding general materials.

Binder type: Flexible binders (such as resin binders) are suitable for applications with high sharpness and allow the abrasive to break at the right time to maintain sharpness.

Abrasive arrangement: The arrangement of abrasives in the grinding wheel affects sharpness, and regular arrangement of abrasives can provide more consistent sharpness and cutting force.

Grinding wheel dressing: After the grinding wheel is used for a period of time, the abrasive particles are passivated, and the sharpness needs to be maintained by dressing, and the grinding wheel can recover the grinding performance after dressing.
