Vitrified grinding wheel for gear honing 'V505J'

Vitrified grinding wheel for gear honing 'V505J'

Vitrified grinding wheels suitable for honing various types of gears.

We propose the vitrified grinding wheel 'V505J' for gear honing, in response to the needs for reducing processing time, improving dressing intervals, and enhancing gear precision as part of our ongoing efforts to reduce vehicle noise. Vitrified grinding wheels offer superior durability due to their strong bonding agents compared to traditional epoxy and hybrid types, allowing for improved dressing intervals and tooth profile accuracy. However, vitrified grinding wheels are inherently weak against impact. To address this, we have applied a resin impregnation treatment to enhance impact resistance and shape retention characteristics. 【Features】 ■ Significant improvement in durability ■ Chip prevention through resin impregnation treatment *For more details, please download the PDF or feel free to contact us.

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!! ↓↓↓
