The “Ultra Porous Grinding Wheels” exceeds the porosity of conventional designs by incorporating a next-generation bond system that ensures uniform dispersion of micro-pores, resulting in substantially enhanced grinding efficiency and performance.

1. The low abrasive grain ratio significantly enhances cutting performance.
2. By suppressing grinding heat, it reduces workpiece distortion and minimizes the risk of grinding burn and cracks.
3. Allows for deeper cuts.
4. Extends dressing intervals.
5. Reduces the amount of dressing required.
6. Minimizes workpiece deflection caused by normal grinding resistance.
7. Contributes to overall cost reduction in grinding operations.

By reducing the abrasive grain concentration, deeper cuts can be achieved without compromising machine rigidity.
