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.

Introduction of the mold grinding stone "YTM" - Samples available.

Perfect for final finishing and mirror polishing!

The product we would like to introduce from our main product line of mold grinding wheels is the "YTM." The "YTM" is a resin-based grinding wheel developed for the final finishing and mirror polishing of molds. It provides a wonderful gloss due to its soft touch and moderate strength (equivalent to wood chips). It is ideal for corners and grooves that are difficult to polish with paper, and it achieves more than five times the gloss compared to ceramic grinding wheels. The grinding wheels are color-coded by grain size, making them easy to manage, and they can be safely used for polishing non-ferrous metals. The hardness of the grinding wheels comes in two types: hard and soft. *Due to being a flammable solid, please ensure that the grinding wheels are dried naturally. They can be a fire hazard. We are currently offering free samples, so please feel free to contact us for more details! ↓↓↓
