Peripheral grinding size：11A2-D200-H40-W15-X10， W20
2021.5.22 Test Czech D20 custom material formula, hardness 118, density 1.965
Grinding blade: CCGW09T304 element6 010PCD
When used on the Taixing grinder, the consumption of the first 7 pieces is almost the same as that of Singapore Airlines. The insert compensation is 0.45, 0.462, and the insert compensation is reduced to 0.23 when entering the stable shedding state. The speed of Sihard can not exceed 1500, and the grinding can not move.
Efficiency of Sihard: 30 tablets 4 hours,while Moresuperhard can reach 50 tablets 4 hours.
The installation of Sihard grinding wheel needs dressing, and there is bouncing.
Moresuperhard almost need no dressing, abrasive falling off stable and 200 times magnification without collapse.

Feedback of worker is still D20 customized formula is easy to use, long life, high efficiency, but D20 conventional formula is also better than Sihard, life efficiency is higher than them.

Moresuperhard recommends ceramic bond diamond grinding wheels for the rough grinding of the cylindrical surface of the diamond layer on PDC cutters. These wheels demonstrate excellent efficiency and cost-effectiveness compared to traditional resin bond wheels.
PCD tools offer excellent hardness and wear resistance for machining difficult materials, but grinding them poses unique challenges. This article explores common issues such as chipping, high surface roughness, dimensional deviations, burning, and grinding wheel wear. Learn practical solutions to optimize grinding parameters, wheel selection, and machine accuracy to improve tool life and reduce costs.
