Ceramic composite cutting wheel

Ceramic composite cutting wheel

A ceramic composite cutting wheel born in Germany.

This is a cutting wheel used for electric disc grinders. It is made from four elements: abrasive grains, bonding agents, pores, and ceramics, achieving an unprecedented long lifespan. - The grain size is #46, which is equivalent to standard cutting wheels. - The hardness is #S, making it softer than standard cutting wheels (being too hard tends to increase the likelihood of clogging and blinding). - The type and classification of the artificial grinding material is #A (brown alumina grinding material). It is ideal for cutting metals such as general steel, cast iron, stainless steel, and carbon steel. Feedback from users indicates that cutting non-metals like mortar and stone was smooth.

Dedicated grinding wheel for GaN/Al2O3 high brittle materials

Dedicated grinding wheel for GaN/Al2O3 high brittle materials

Elimination of clogging due to the pore effect! High-lifespan grinding wheels with minimal wear.

This product is a high-precision grinding wheel specifically designed for GaN/Al2O3, which achieves sufficient supply of grinding fluid by dripping it from within the grinding wheel to the workpiece. By supplying the grinding fluid from within the grinding wheel, we have enhanced the efficiency of the grinding speed and the prevention of clogging, which has been a challenge in the past. It prevents variations in grinding performance due to temperature changes and early carbonization caused by localized temperature rises in the grinding wheel, enabling stable grinding operations. 【Features】 ■ Realization of grinding fluid supply from within the grinding wheel ■ Significant reduction in edge chipping ■ Concentration of 180, greatly improved grinding efficiency ■ Vitrified bonding ■ Clogging prevention through pore effects *For more details, please refer to the PDF document or feel free to contact us.
