Currently used in traditional ordinary abrasive granular slow grind main advantages are high precision, but also has some disadvantages in inch: such as:
     1, the abrasive grinding disc is placed loose on the disc speed is not too high to avoid splashing abrasive, abrasive waste, so processing efficiency is low.
      2, abrasives and grinding from the workpiece under the debris mixed together, the abrasive can not play a full role, but also to improve the processing efficiency with these often abrasive debris washed together, both to waste energy, but also a waste of abrasive .
      3, abrasive grinding discare randomly distributed, and its distribution uneven density of the workpiece material grinding cutting uneven workpiece surface accuracy is difficult to control; particularly abrasive and the workpiece relative motion between the randomness, which also increases to see work face accuracy can not afford to identify factors that reduce the stability of the machining accuracy.
       4, the grinding process, the abrasive forces between each other, but also the relative motion, which results in the abrasive cutting action between both abrasives abrasive, abrasive and increased energy waste.
       5, in the grinding process, the large size of the abrasive to withstand greater pressure, and the small size of the abrasive is exposed to a small pressure, even independent of pressure, which makes large cutting depth large abrasive particles, resulting in deep scratches, impact surface quality, so as to improve surface quality, the abrasive loose abrasive grain size uniformity higher.
       6, in the strictly controlled grinding medicine flow of coolant to avoid abrasive away, the cooling effect of variation which is easy to cause the workpiece to heat up, resulting in decreased precision machining.
       7, in the grinding process, the disc will also affect the wear and tear resulting flatness of the workpiece, which would often dressing millstones, while trimming disc requires three relatively abrasive disc, both cumbersome and troublesome, high technical requirements for workers, the best choice shaving machine, repair disk only needs 10 minutes, flatness up to 0.002mm.
        8, in order to avoid the coarse abrasive particles are used in large grinding process to the next channel, the impact of the quality of precision machining, the polishing step requires a rigorous cleaning of the workpiece.
        9, according to standard processing fee abrasive to avoid pollution of the environment, to be environmentally friendly.
      10, the hard abrasive easy to embed a softer surface, the impact of work performance, conventional particulate abrasive polishing precisely because of the existence of the disadvantages that its application has been a certain limit.
