Main factors affecting grinding wheel grinding performance.

The surface morphological characteristics of the grinding wheel are the main factors affecting the grinding performance of the grinding wheel. The surface morphological characteristics of the grinding wheel mainly include the number of abrasive grains, the geometry and distribution of abrasive grains, the cutting edge of abrasive grains and the height of the cutting edge. They are important input parameters of the grinding process and directly affect the grinding performance.

Surface profile inspection methods of grinding wheels.

The inspection method can be divided into indirect inspection method and direct inspection method

The indirect detection method uses the physical signals generated during processing to complete the detection, such as detecting force, sound, vibration and other signal parameters to determine the surface profile of the grinding wheel; for example, the grinding force and grinding temperature of the grinding wheel can reflect the sharpness of the grinding wheel, so the corresponding physical data can be measured with a force meter to determine the sharpness of the grinding wheel.

The direct inspection method usually involves direct analysis of the grinding wheel surface shape with the help of physical probes or optical instruments. The contact type is, for example, scanned by a stylus. For non-contact types, the common test is the microscope collimation method.
