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.
