三井研削砥石 Product Lineup

The "HORNET series" diamond dresser is made from polycrystalline diamond produced by the CVD method (chemical vapor deposition), ensuring that the product lifespan remains unchanged regardless of which side is used. It delivers uniform and stable performance throughout its lifespan. 【Features】 ○ High-performance polycrystalline diamond dresser For more details, please contact us or download the catalog.

• Grindstone

The GMS wheel series has been cherished for many years as "Goma Shio to Ishi" and is a low-density vitrified wheel with air pores developed by Mitsui ahead of others. It allows for easy truing with single stone dressers and impregnated dressers, and due to its high grinding performance unique to super abrasives, it demonstrates exceptional power in processing hard-to-machine materials such as high-speed steel with HRC hardness over 60 and SUS440C. 【Features】 ○ Excellent dressing capability ○ Reduced processing time ○ High processing precision ○ Minimal grinding wheel wear For more details, please contact us or download the catalog.

• Grindstone

This is a diamond wheel series focused on longevity. It boasts a high grinding ratio under processing conditions where workpiece chips are less likely to weld and grinding resistance is not easily increased. 【Features】 ○ Long-life diamond wheel For more details, please contact us or download the catalog.

• Grindstone

It demonstrates high grinding performance for easily weldable non-ferrous metals such as aluminum alloys, as well as extremely hard non-metal materials like various ceramics and sapphire glass. It makes gentle contact with the workpiece, producing a light grinding sound. Additionally, it boasts exceptional cutting ability, allowing for deep cuts. 【Features】 ○ Diamond wheel with outstanding cutting ability For more details, please contact us or download the catalog.

• Grindstone

The newly developed bond filler has achieved high lubricity and comfortable dressability. Due to the high retreatability of the bond matrix, sufficient protrusion of the abrasive grains is ensured, demonstrating excellent cutting performance. Additionally, the strong abrasive grain retention provided by the high heat-resistant bond developed in the D series has resulted in high processing accuracy and long lifespan. 【Features】 ○ Achieves a high level of both improved cutting performance and extended lifespan. For more details, please contact us or download the catalog.

• Grindstone

This is a high-performance CBN wheel series developed with the aim of significantly extending the lifespan from the L series. It demonstrates excellent grinding performance in various rough grinding operations with a large amount of material removal and high-precision machining with fine particles, thanks to its high heat resistance and strong abrasive retention. 【Features】 ○ Achieves a significant extension of tool life For more details, please contact us or download the catalog.

• Grindstone

This is a highly reliable wheel series that is used by the most customers. It is a versatile CBN wheel series that is easy to set search conditions and dressing, and has the widest range of applications. It can process all types of iron-based materials, including compressor parts, automotive parts, and bearing components. 【Features】 ○ Standard CBN wheel series boasting high reliability and proven performance For more details, please contact us or download the catalog.

• Grindstone

It demonstrates unprecedented grinding performance in cylindrical and centerless grinding at speeds below 45M/SEC. The wide range of wheel condition settings due to changes in dressing conditions allows for better surface roughness compared to conventional segmented wheels, provided the same grain size is used. Therefore, it can flexibly respond at a high level to needs ranging from lifespan-focused to precision-focused through changes in processing conditions. 【Features】 ○ Ultra-high performance ○ Completely integrated For more details, please contact us or download the catalog.

• Grindstone

Compared to conventional wheels, it allows for deeper dressing cuts, providing a wide range of settings from sharpness-focused to high-precision-focused, and adjustments are easy. Due to its good dressing characteristics, dressing time is significantly reduced. The low variation in the density of the abrasive layer results in less fluctuation in grinding performance, greatly extending the dressing interval. 【Features】 ○ Overwhelming ultra-high precision processing ○ Long lifespan For more details, please contact us or download the catalog.

• Grindstone

In the production of vitrified CBN diamond wheels, the integral molding of the abrasive layer and the ceramic body requires extremely advanced manufacturing technology. By merging the long-established grinding wheel manufacturing techniques with newly developed production technologies, we have achieved complete integral molding of the abrasive layer and body layer. 【Features】 - Integral molding - Uniform abrasive layer - Multi-type with minimized adhesive gaps For more details, please contact us or download the catalog.
