LEMAN cutting wheels Sintered metal bonded grinding wheel

Mostly bronze and other metals as a binding agent, with a high temperature sintering method, which combines high strength, good formability, high temperature, thermal tile cutting wheels‍ conductivity and good wear resistance, long life, can withstand greater loads. Wheel in the sintering process because there is inevitably shrink and deformation, so before shaping the grinding wheel must be used, but it is rather difficult dresser. Currently used in the production of plastic wheel to roll in the dressing method not only time-consuming, but the process of trimming off the diamond particles are more wheel dressing itself consumes large, low-shaping accuracy. 

In recent years, scholars from various countries metal cutting wheels have been carrying out a study of the application of special processing method of finishing work metal bond diamond wheel, mainly electrolytic dressing, French dressing and composite trim EDM method. Electrolytic dressing method is fast, but shaping accuracy is not high; high precision EDM shaping trimming method, can be either plastic dressing, but shaping slower; composite trimming method spark composite electrolytic dressing, mechanical chemical compound trimming method etc., dressing better, but the system is more complex, and therefore sintered diamond wheel trim problem still has not been solved. Further, since the grinding wheel determines the manufacturing process is a random surface topography, geometry of the abrasive grains, the distribution and the height of the cutting edge which is inconsistent, so that only a few high cutting edge to cut the workpiece, the cutting wheels‍ grinding limit further improve the quality of grinding and grinding efficiency.
