Description of Double Disc Grinding Wheel:
More SuperHard company offers a full line of diamond and CBN grinding wheels and dressing stones for fine grinding machines and single and double side lapping systems. Our vitrified diamond and CBN grinding discs have high grinding efficiency, high wear resistance and abrasive consumption, good surface quality and flatness of the workpiece.
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.
Applicable Areas of double discs:
♦ Hydraulic pneumatic components. vane pump, conversion valve, piston pump,fuel pump, hydraulic motor parts
