Responding to industry demands for enhanced abrasive productivity, worker safety, and sustainability, FUJI Grinding Wheel strives to foster innovation. We continuously develop a new generation of abrasive tools, including the "KOSOKU" Precision Metal Cutting Machine and FUJI High-Frequency Power Tools.
We are committed to ensuring that our premium products help clients increase productivity, reduce dust and noise in the workplace, and improve worker comfort. Our solutions enable success every day, from the first cut to the final finish.

The FUJI "KOSOKU" Precision Metal Cutting Machine represents a leap forward in cold-cutting technology. Unlike traditional abrasive chop saws that generate excessive heat, dust, and burrs, KOSOKU machines are engineered for environmental compliance and operational speed.
Heavy-duty grinding in environments like shipyards and foundries involves removing massive amounts of material. A common issue with standard air (pneumatic) or universal electric grinders is speed drop—when the operator presses down, the wheel slows, extending the process time and increasing fatigue.
The FUJI Solution: Our High-Frequency (HF) machines, operating at 240Hz, 250Hz, or 400Hz, utilize advanced induction motors that maintain a constant rotation speed even under maximum load. This "High Output, High Torque" capability allows operators to remove material faster without the tool bogging down.
The FUJI High-Frequency Grinder lineup includes various power outputs, specifications, and models to suit your specific industrial requirements. Depending on the configuration, a complete set ranges from $1,200 to $2,000 USD, providing exceptional ROI through vastly improved productivity and reduced maintenance.
For medium to heavy-duty grinding operations, our 7-inch HF Angle Grinder is the definitive choice. It is expertly balanced and engineered for optimal material removal.
| Feature | Standard Electric/Air Tools | FUJI High-Frequency Tools |
|---|---|---|
| Speed Under Load | Drops significantly (30-40%) | Remains Constant (< 5% drop) |
| Motor Maintenance | High (Carbon brushes/Air leaks) | Zero (Brushless Induction Motor) |
| Productivity | Standard | High (30% faster removal) |
These tools are compatible with standard wheels running at a peripheral speed of 72 m/s (4,200 m/min) or high-speed wheels at 80 m/s, directly translating to lower operational costs through improved efficiency.
High-Frequency grinders offer significantly higher energy efficiency (lower electricity costs compared to compressed air) and maintain constant speed under load, which pneumatic tools often fail to do. They are ideal for heavy-duty environments like shipyards.
The specific requirements depend on the model and material, but KOSOKU machines are designed for dry cutting precision that minimizes heat transfer, often removing the need for messy coolants in standard applications.
