Only natural diamond grinding wheel cutter or diamond roller can dress other tools, because the hardness is not as good as diamond, so it is difficult to dress. I'm Xiao Zhang from Chang 'an Engine Factory. Our factory often uses diamond grinding wheels. The dressing tool we use is the natural diamond grinding wheel tool provided by Chongqing Changjiang Diamond Tool Factory. It has been used for several years, the quality is very stable, and there has never been a problem.
