Semifinishing grinding wheels

Semifinishing wheels are used for high-precision centerless rectification of steel bars and tubes. The technical properties of the bond combined with an optimal grit size of the abrasive grains enable self-dressing of the wheel and offer great results for different steel types. Our semifinishing wheels can be used for rough griding, where high removal rates are important, for smoothing the surface after previous machining steps in order to achieve perfect dimensional parameters, and for obtaining an intermediate surface finish in preparation for finishing and superfinishing. The exact application depends on factors like abrasive grit size, bond hardness and structure as well as parameters of your grinding process.
