The role of the pores in the choice of grinding wheel

Select wheel organization, the grinding wheel stomatal grinding
The grindstone tissue refers to the abrasive grinding wheel, binding agents, pores among the volume relationship. Obviously, the larger the volume occupied by the pores in the grinding wheel, the grinding wheel is more loose, in essence, is to choose the volume occupied by the stomatal grindstone. Therefore, can not be ignored stomatal grinding capacity of debris and the cooling effect. When grinding low hardness and toughness of the material, or the contact area of ??the wheel and workpiece (with the large plane of the grinding wheel face grinding), and the processing viscous difficult to grind materials, BTA more difficult, the cooling condition is not good, then the number of errored close grinding wheel with the organization, will definitely lead to adverse consequences of the grinding wheel wear debris clogging surface burns. Such as changing the porosity, the tissue loose wheel, not only the larger chip space can thick wear debris away, to prevent the flap wheel clogging, to reduce the workpiece surface scratches; large pores may also be more cutting fluid into the grinding area, to enhance the cooling effect, to prevent the workpiece surface burns.
