Specifications Comparison

WH-BH7

This grinding wheel has good self-sharpening effect, so even etched surfaces that are difficult to grind without dressing can be ground continuously without dressing. Due to the use of high-performance bond types and grinding wheel design, the grinding resistance is small, the service life is long, and a high grinding ratio can be obtained.

WH-BH14

This grinding wheel employs a filler that reduces grinding resistance and a multi-porous structure, allowing grinding operations to be completed under extremely low loads. When grinding wafers, it minimizes damage and achieves excellent surface finish quality.

WH-VDW

This grinding wheel successfully ensures the uniform distribution of fine diamond abrasive grains, eliminating the scratching issues commonly associated with ceramic bonds. Due to the strong abrasive retention of the ceramic bond, high-precision mirror-like surface finish grinding can be achieved.

Additionally, this grinding wheel is a multi-porous wheel, which can suppress the increase in grinding resistance.
