the grinding wheel's role in stomatal

 Wheel Organization means of abrasive wheel, binders, pore volume of the relationship between the three. Obviously, the pores in the volume occupied by the larger wheel, the wheel the  abrasive paper sheet more loose, in essence, is to choose the pore volume occupied by the grinding wheel. Therefore, the pores can not be ignored in the chip in the grinding and cooling effect. When low hardness grinding toughness of the material, or the grinding wheel and workpiece contact area (with a large flat face grinding wheel), and the processing of viscous materials that are hard, the abrasive disc  chip is difficult, the cooling condition is not good, this time as errors closely with the organization's wheel, the wheel will definitely lead to blockage by debris, surface burns and other adverse consequences. Such as for a large porosity, loose tissue wheel, not only can a large chip space debris away thicker, to prevent clogging wheel, reducing the surface scratches; larger pores can be more cutting fluid into the grinding zone, enhancing the cooling effect, prevent the workpiece surface burns.
 Must be pointed out, wheel too loose, it will cut off disc  lead to faster wheel wear, short life, need regular trimming wheel, replace wheel, grinding affect productivity; forming grinding and precision grinding, grinding wheel is not conducive to maintaining a work-surface formability, and reduce machining accuracy. At this point, should choose a more compact organization of the wheel.
