Introduction of the mold grinding stone "YHB-T" - Samples available.

Introduction of the mold grinding stone "YHB-T" - Samples available.

The mold grinding stone with the highest strength in the YH series.

The product we would like to introduce from our main product line of mold grinding wheels is the 'YHB-T'. This is a ceramic grinding wheel for rough to medium finishing, which is impregnated with high-fracture-resistance phenolic resin in WA grinding wheels, and it is the strongest product in the YH series. It provides a smooth finish when cutting and removing the altered layer of materials after machining or electrical discharge machining, especially when surface roughness is a priority. Additionally, due to its strength, it is less likely to break during roughing operations under load or when working with small-sized grinding wheels. However, it tends to clog easily in dry conditions, so please use it wet. We recommend "BLUE CUT" from our company. The hardness of the grinding wheels comes in three types: "L" (hard), "J" (medium), and "H" (soft). Currently, we are offering free samples, so please feel free to contact us for more details!! ↓↓↓

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

It has a strong retention of sulfur intensity, is difficult to break, and has excellent workability.

The product we would like to introduce from our main product line of mold grinding stones is the product called "YHS." This is a grinding stone that has sulfur impregnated into a WA grinding stone. By adhering sulfur to the pore walls of the grinding stone, it can prevent grinding marks on molds. It has a moderate strength retention of sulfur, making it less likely to break and excellent in workability. Additionally, the lubricating effect of sulfur improves the surface roughness of the mold and significantly reduces the wear of the grinding stone. The hardness of the grinding stone is of type "I." (Note) As it is a flammable solid, please ensure that the grinding stone is dried naturally. It may cause a fire.
