Ceramic CBN internal grinding wheel is used to process products with high dimensional accuracy, good consistency, and high requirements for straightness and roundness. High hardness, high strength and high toughness materials that are difficult to be processed by ordinary internal grinding are very easy for superhard grinding tools. Now they are widely used in bearing industry, sewing accessories industry, mold industry, auto parts (oil pumps and nozzles), vane pump parts, refrigeration compressor parts, engineering ceramics and other industries. Good results have been achieved in various internal grinder, coordinate grinder and internal surface grinder.

1. the grinding wheel structure is evenly distributed, and the grinding work piece is not easy to burn.
2. the dressing frequency is low and the shape of the grinding wheel is well maintained. The dressing can continuously grind 500 ~ 2000 parts at a time, which is 300-500 times the service life of ordinary grinding tools of the same specification.
3. high machining accuracy and good dimensional consistency of batch parts.
4. the comprehensive cost is low. Considering the cost of equipment, personnel and effective time, the comprehensive cost can be reduced by about 1/3.
5. the grinding surface of the parts is of good quality, without burn or deterioration.
6. customized production can be carried out according to different work pieces and different customer needs.
-Cast iron: chilled cast iron, ball milled cast iron, grey cast iron, alloy cast iron, etc.
-Steel parts: 20Cr, GCr15, 45 steel, 55 steel, etc.
1. dressing tools: diamond pen (multi-point, powder metallurgy) or roller can be used, and diamond roller is preferred.
2. dressing: the consumption of diamond pen and roller will be greatly reduced by the reduction of wheel speed; Finishing time Reduce the speed of the grinding wheel. After the shape is repaired, mention the use speed, micro feed 1 µ m and finish it again, which can be used for grinding the work piece.
3. dressing amount: the single dressing feed shall not exceed 0.003mm, and the dressing amount of each dressing cycle shall not exceed 0.02mm.
4. dressing travel speed: the grinding wheel with the same granularity pursues the grinding efficiency and shortens the grinding time, which can appropriately improve the travel speed of the dressing tool on the use surface. If the roughness is not ideal, the dressing speed can be reduced, and the roughness will be improved to a certain extent.
