Diamond wheels carbide, glass, ceramics, gem high brittle material effects tools. In recent years, with the rapid development of high-speed grinding technology of ultra-precision grinding, grinding wheels put forward higher requirements, ceramic resin bonded grinding wheel has been unable to meet production needs, metal bonded grinding wheel because of its combination of high strength, good formability, Notable features of long service life and production has been widely used.
Metal-bonded diamond grinding wheel manufacturing different ways there are two types of sintered plating. In recent years, scholars have launched a special processing method applied metal bond diamond wheel trim work, mainly electrolytic dressing method, EDM trimming method Composite trimming method. Electrolytic dressing method faster, but shaping accuracy is not high; high precision EDM shaping trimming method, either plastic but also dressing, but plastic is slower; composite trimming method electrolytic composite EDM dressing, mechanical chemical compound trimming method etc., dressing better, but the system is more complex, and therefore a sintered diamond wheel dressing the problem still has not been solved.
Furthermore, since the grinding wheel manufacturing process to determine its surface morphology random, each grain geometry, distribution and high degree of inconsistency in which the cutting edge, so only a handful of high grinding cutting edge to cut the workpiece, limiting the grinding quality grinding efficiency is further improved.
