Hardness than corundum, abrasive easily broken, sharp edges and corners, good cutting, grinding heat and small.

硬度高于棕刚玉，磨粒易破碎，棱角锋利，切削性能好，磨削热量小等。

Diamond CVD coating process is introduced to increase the surface hardness of cutting tools.

为增加切削刀具表面硬度引入了钻石化学蒸发沉淀涂层工艺。

The clamping claw with high hardness, and intermittent cutting, so that when the cutting depth and cutting amount is small, the cutting speed is not too high.

因卡爪硬度较高，又系断续切削，所以修正时切削深度和走刀量要小，切削速度也不宜太高。
