Back to determine the amount of knife
24 4月 2018 | 没有评论 | posted by admin | in Article
The amount of back knife is determined according to the stiffness of the machine tool, workpiece and tool. Under the condition of permissible rigidity, the amount of the back tool should be equal to the machining allowance of the workpiece. This can reduce the number of passes and increase the production efficiency. In order to ensure the quality of the processing surface, can leave a small amount of finishing allowance, generally 0.2 – 0.5mm.
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.

(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
