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.
The resin wheel at different purposes there are different types of grinding wheel, parallel to the grindstone is mainly used for the carbide cylindrical grinding and edge processing; parallel with arc grindstone is mainly used for grinding, circular arc surface of the carbide forming molded grinding cut; sided concave grinding wheel for grinding the gages and coreless matte turbine; dual hypotenuse wheel is mainly used for carbide gear hobs, thread cutter molding grinding; bowl-shaped grinding wheel: mainly used for carbide sharpening of cutting tools, high speed steel cutting tools can also be used for milling.
Resin grinding wheel, also known as resin knife grinding wheel, resin grinding wheel, depending on product model variety for the election (parallel to the grinding wheel, parallel with the arc grinding wheel sided concave grinding wheel, double hypotenuse grinding wheel, bowl-shaped cutting wheel). Diamond resin grinding wheel with a good polishing, grinding grinding wheel sharp, easy to plug, currently grinding, cutting metal industrial use is very common.
