The regrinding of CBN tools

CBN tool should be regrinded before the surface roughness bad, otherwise it will be easy broken-down. The regrinding of CBN tools should be made on the tool grinding machine. The tool with light wear can be enlarged the nose radius to grind off the wear area. 

There are two steps when regrinding the tool flank face-rough grinding, finish grinding, Rough grinding should use the resin bond diamond grinding wheel with the grit size 240mesh to 320mesh, and the return feed rate is 0.02-0.05mm/each time. 

Finish grinding should be use the grit size 600 to 800 mesh, and the return feed rate is 0.005-0.002mm/each time. 

Dry grinding is the normal way
