We would like to introduce our "Super Finishing Stone/ZP Stone." The "Super Finishing Stone" applies vibrations to the grinding stone, exerting forces on the abrasive grains from multiple directions, making it easier for the grains to break and fall off, while maintaining a consistently sharp cutting edge. This ensures the grinding performance of the stone. The "ZP Stone" is a grinding stone that meets environmental standards by not using materials such as lead, which are harmful to the environment. It has a good pore balance and achieves suitable grinding performance. 【Features of the Super Finishing Stone】 - Facilitates the breaking and falling off of abrasive grains, maintaining a consistently sharp cutting edge - Ensures the grinding performance of the stone - Processes at lower pressure and speed compared to general machining - Generates almost no heat, resulting in extremely low machining alteration compared to grinding - By using specialized machinery, it achieves high precision in surface roughness and shape accuracy economically in a short time *For more details, please refer to the PDF document or feel free to contact us.

• Grindstone

The "Kirara Electric Type 4" is a compact polisher that fits comfortably in your hand. Its exquisite weight balance reduces fatigue during work. Water is sprayed radially from the tip of the main shaft, providing an optimal wet effect. It is also equipped with a grinding wheel cover designed with safety considerations based on regulations. By valuing the basics, it has become light, powerful, and easy to use. 【Features】 ■ Comfortable form for the hand ■ Unique water injection method ■ Safety-conscious design *For more details, please refer to the PDF document or feel free to contact us.

At Sanwa Grinding Industry, we achieve the optimal combination from the blending of abrasive grains, bonding materials, and the firing conditions of grinding wheels to the design of wheel shapes, utilizing over 60 years of accumulated grinding know-how and more than 3,000 grinding wheel recipes. 【Features】 - Short delivery times - Free design costs - Free estimates *For more details, please contact us or refer to our catalog.

• Other abrasives

The hard, sharp cutting edges of super abrasives (diamond/CBN wheels) excel in cutting performance, achieving high efficiency, long lifespan, and a high grinding ratio. They are suitable for a wide range of applications, including surface grinding (flat grinding), cylindrical grinding, internal grinding, profile (contour grinding), tool grinding, chamfering, and regrinding of cutting tools. 【Features】 - The abrasive grains are held by thermosetting synthetic resin, providing a soft touch due to moderate elasticity, resulting in good surface roughness. - The cutting performance is outstanding, and dressing and truing can be easily performed. - The wheel design allows for use in both wet and dry applications. *For more details, please contact us or refer to the catalog.

We would like to introduce our "Diamond/cBN Wheels." In the world of machining, diamonds and cBN are referred to as super abrasives, possessing several times the hardness compared to conventional abrasives like SiC and WA. The sharp cutting edges of these super abrasives excel in cutting performance, offering high efficiency and long lifespan, and are used in high-precision grinding wheels that produce a high grinding ratio. Additionally, they effectively dissipate heat from the grinding point to the wheel side, helping to prevent thermal alteration of the workpiece surface. 【Features】 ■ High efficiency and long lifespan ■ High-precision wheels with sharp cutting performance ■ Several times the hardness compared to conventional abrasives like SiC and WA ■ Effectively dissipates heat from the grinding point to the wheel side *For more details, please refer to the PDF document or feel free to contact us.
