Electroplated diamond grinding wheel defects exist

Electroplated diamond grinding wheel defects exist :
1 , using a large positive rake angle machining, tool wear serious , cutting vibration is large, and the substrate and  diamomd core drill bits the coating metal surfaces are not kept firmly binding the abrasive chemical metallurgical bonding , actually only be mechanically entrapped abrasive coating metal mosaic , thus dominated force is small ;
2, the diamond particles heavier load efficiency, for processing efficiency, processing quality , processing costs, and a great influence on the grinding tool life easy to fall off ( or plating flaking ) and lead to an overall failure ;
3 , to increase the holding force Edge 2000 Pads  must be increased coating thickness , and the results highly abrasive bare chip space is reduced, wheel prone to clogging , the cooling effect is poor, prone to burn the workpiece surface ;
4 , the current domestic electroplated grinding wheel manufacturing has not been achieved by optimized processing conditions required to design the best grinding wheel topography, in the domestic diamond coating technology is still in its infancy , as well as the cost of  diamond cbn wheel inputs are big , so in the near future diamond coating there is not much development ;
5, the tool angle change on the tool wear, cutting force and cutting vibration is rake angle , clearance angle and helix angle integrated generated , so the choice we must pay more attention to single-layer electroplated diamond grinding wheel will be significantly restricted these inherent drawbacks its efficient grinding applications .
