Diamond fast cheap metal grinding disc is a special tool for grinding hard and hard materials such as cemented carbide, glass, ceramics, and precious stones.
The electroplated diamond/CBN grinding disc is an electrochemical/diamond/CBN grinding disc. The working layer of the grinding disc contains diamond or CBN abrasive grains, and the diamond/CBN abrasive is bonded to the substrate by a metal bonding agent.
Electroplated diamond fast cheap metal grinding disc advantages:
1. The electroplating process is simple, the investment is small, and the manufacturing is convenient;
2.No need to trim, easy to use;
3. Single-layer structure determines that it can reach a very high working speed, currently abroad has been as high as 250 ~ 300m / s;
4. Although there is only a single layer of diamond, there is still enough life;
5.For the precision requirements of the roller disc, the plating manufacturing method. Due to these advantages, high-speed, ultra-high-speed grinding of electroplated grinding discs occupies an undisputed dominant position.
Plating fast cheap metal grinding disc storage defects: there is no strong chemical metallurgical bonding between the plating metal and the substrate and the abrasive bonding surface. The abrasive material is actually only embedded in the inlaid coating metal, so the holding force is small, the diamond particle load is heavy, and the grinding is easy to fall off. (or the coating is peeled off into pieces), resulting in overall failure; in order to increase the holding force, the thickness of the coating must be increased. As a result, the bareness of the abrasive grains is reduced, the fast cheap metal grinding disc is prone to blockage, the heat dissipation effect is poor, and the surface of the workpiece is prone to burns. At present, the domestic electroplated grinding disc manufacturing has not yet achieved the optimal design of the fast cheap metal grinding disc according to the processing conditions. The inherent disadvantages of the single-layer electroplated diamond grinding disc will inevitably limit its efficient grinding application.
