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。
2
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。
3
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.
