Natural single crystal diamond

Natural single crystal diamond is the most wear resistant material in diamond. It is finely grounded and finely ground. The radius of the blunt edge of the cutting edge can be as small as 0.008 to 0.005 μm. However, natural single crystal diamond is brittle, its crystal anisotropy, crystal hardness of different crystal faces or the same crystal face in different directions are all different, and must be selected in the appropriate direction when sharpening and using. Because of the harsh conditions of use, natural monocrystalline diamond resources are limited, and the price is very expensive, so PCD, PCD/CC and CVD diamond tools are mostly used in production.
Impact on the life of diamond saw blades – sawing parameters

(1) Line speed of the saw blade: In actual work, the linear speed of the diamond saw blade is limited by the equipment condition, the quality of the saw blade and the nature of the sawed stone.
(2) Sawing depth: The sawing depth is an important parameter involving diamond abrasion, effective sawing, the condition of the saw blade, and the nature of the sawn stone.
(3) Feed speed: The feed speed is the feed speed of sawing stone. Its size affects the sawing rate, blade force, and heat dissipation in the sawing area. Its value should be selected according to the nature of the sawn stone
Abrasive features

Abrasives are tools for grinding, grinding and polishing. Most of the abrasives are artificial abrasives made of abrasives and binders, and are also natural abrasives that are directly processed from natural mineral rock. In addition to being widely used in machinery manufacturing and other metal processing industries, abrasive tools are also used in grain processing, paper industry, and non-metallic materials such as ceramics, glass, stone, plastic, rubber, and wood. In the course of using the abrasive tool, when the abrasive particles are blunt, the abrasive particles partially or completely fall off from the abrasive tool due to the part of the abrasive particles being broken or the bonding agent is broken, and the abrasive material on the working surface of the abrasive tool is constantly undergoing new cutting. Edge, or constantly exposed new sharp abrasive particles, so that grinding tools can maintain cutting performance in a certain period of time. This self-sharpening of the grinding tool is a prominent feature of the grinding tool compared with general tools.
