Advantages of Top and Bottom Grinding Wheels
1. High grinding efficiency,Long service life and Good shape retention.
2. High strength synthetic diamond for high removal rates while excellent finish.
3. Sharp shape synthetic diamond for long dressing intervals.
4. Free cutting design for low cutting energy.
5. Better cutting edge with smaller chipping.
6. Good uniformity of size because the stable uniform structure and materials in abrasive layer.
7. High flatness, good finish, and parallemism.
8. Save your labor costs.
