By curling the feathers and strengthening the waist, we have overturned the conventional wisdom of soft polishing cloths. With a strong waist, the pressure of the polishing head is effectively utilized on the polishing surface, while the softness of the material prevents excessive biting. We want to create a polishing wheel with excellent finishing properties using a soft and well-fitting polishing cloth, along with fine grit for grinding power. One answer to the polishing wheel we seek is the SF wheel. 【Applications】 ■ Pre-treatment for plating ■ Polishing motorcycle rims ■ Surface polishing of stainless steel pots 【Features】 ■ A polishing material that combines moderate softness with strong support. ■ High grinding capability despite being fine grit. 【*For more details, please contact us or refer to the catalog.】

The "NS Wheel" is a polishing wheel of the windmill type with a suitable arc in an umbrella shape, ideal for deburring tasks on the end faces of pipes. By combining NS Wheels with different orientations, it can also be used as a polishing wheel for heavy grinding. Additionally, due to its moderate adaptability and air cooling effect, there is no concern about burning. 【Features】 ■ High friction resistance on the surface, leading to rapid temperature rise necessary for polishing ■ High grinding ratio due to its abrasive polishing nature ■ The blades themselves have moderate flexibility, making them easy to conform to curved surfaces ■ Even in cases of excessive pressure, the wheel itself exhibits a floating effect *For more details, please refer to the PDF document or feel free to contact us.

The "GF Wheel" is a highly regarded grinding wheel for centerless grinding of difficult-to-machine material pipes and for polishing aluminum weld beads. By increasing the number of flaps on the outer circumference by approximately 25% to 30% at the base using a unique method, we have created a high-density wheel. This means an increase in the amount of abrasive used over a certain period compared to conventional flap wheels, which simply translates to a difference in grinding power. This difference enables a reduction in grinding processes that was not achievable until now. 【Features】 ■ Incredible grinding power generated by high-density flap tips ■ No risk of breaking ■ Lighter than grinding stones, with lower grinding noise ■ No unnecessary wear or chatter marks ■ Product hardness can be adjusted according to application *For more details, please refer to the PDF document or feel free to contact us.

The "Pipe Rod Grinding Machine P-3C" is a cylindrical pipe horizontal grinding machine manufactured by Shiken, utilizing a centerless method. Boasting over 2,000 units sold, it is a simple machine that is easy to use and offers excellent performance, regardless of the work material or the experience of the grinding operator. In addition to the P-3C model (suitable for workpieces with a diameter of φ7 to φ100), there is also a made-to-order older model, the P-2 (suitable for workpieces with a diameter of φ40 to φ150). Depending on the state of the raw tube and the purpose of the finishing process, a continuous line configuration of 2 to 12 processes is possible. The dry grinding method, which minimizes the impact of grinding heat through the selection of grinding materials, is the mainstream approach. 【Features】 ■ Over 2,000 units sold ■ Easy to use with excellent performance ■ Suitable for workpieces with a diameter of φ7 to φ100 ■ Continuous line configuration of 2 to 12 processes possible ■ Dry grinding method *For more details, please refer to the PDF document or feel free to contact us.

The "Compact Grain Belt" is a grinding cloth made from the composite abrasive "Compact Grain" produced by the German company VSM. As the composite abrasive gradually breaks down during grinding, the grinding pattern remains consistent, and it lasts several times longer than standard grinding belts. Additionally, it maintains stable grinding power over long periods of use. It promises a uniform finish and eliminates variations in quality. 【Features】 ■ Lasts several times longer than standard grinding belts ■ Maintains stable grinding power over long periods ■ Eliminates variations in quality with a uniform finish ■ Suitable for plate grinding, coil grinding, and centerless grinding *For more details, please refer to the PDF document or feel free to contact us.

The "FP Wheel (Flap Wheel)" is a grinding wheel that embeds flaps of abrasive cloth (sandpaper) around its circumference and polishes by striking the flaps at high speed. By gradually wearing down from the tips of the flaps, it can maintain a consistent grinding ability for an extended period. It is the most widely used product in the market as an abrasive cloth wheel and can be used for a variety of applications, such as hand polishing with a buff race, plate grinding on automatic machines, and centerless grinding, as a versatile type. 【Features】 ■ Maintains consistent grinding ability for a long time ■ User-friendly, widely available grinding wheel ■ RoHS compliant ■ Lead-free for balance ■ Option to select the optimal abrasive cloth *For more details, please refer to the PDF document or feel free to contact us.

To increase the required polishing precision, the conventional approach of lengthening the line or increasing the number of passes will undergo a dramatic change with our company's "custom-made polishing materials." By using polishing materials suited to the polishing conditions, appropriate polishing can be achieved, leading to better organization of the line and a reduction in the number of wheels and belts used, as well as their replacement frequency. This creates the potential for significantly shortening the process. Our custom-made polishing materials propose three reductions: 【Three Reductions】 ■ Reduction of processes → Lower production costs ■ Reduction of the number of heads → Space-saving ■ Reduction of polishing time → Increased productivity *For more details, please refer to the PDF document or feel free to contact us.
