Alumina hollow ball /Bubble alumina creat pores in CBN diamond grinding wheels
Alumina hollow ball /Bubble alumina add it to resin powder to create pores for creating holes in CBN diamond grinding wheels.
The diamond grinding wheel has an appropriate amount of pores, which can play a good role in cooling, chip removal and self-sharpening during the grinding process.
