The working surface characteristics of vitrified diamond grinding wheel

1. The abrasive grain size and the position of the abrasive grains on the surface of the vitrified diamond grinding wheel are randomly distributed, which determines that the evaluation parameters of the grinding wheel topography are statistical values, and the instrument for measuring the surface topography of the grinding wheel needs to have a large sampling area;

2. The vitrified diamond grinding wheel is the hardest material known on the earth. When the contact measuring method is used, the wear of the stylus will affect the measurement accuracy, especially when measuring the morphology of the fine-grained diamond grinding wheel.

3. vitrified diamond grinding wheel binders such as ceramics have low reflectivity to light, and it is difficult to obtain satisfactory measurement results using the optical measurement method of the imaging principle. The above characteristics of the diamond grinding wheel make most of the measuring instruments that can be used for measuring the surface topography of general engineering not suitable for the vitrified diamond grinding wheel.
