Regeneration of grinding wheel active surface using high-pressure hydro-jet

Abstract

The possibility of applying a high-pressure hydro-jet for renewal of the grinding wheel cutting ability was presented. This work was conducted in the internal cylindrical grinding process of the Titanium Grade 2^® alloy, which belongs to the group of hard-to-cut materials. The analysis shows that the impact on the erosion effectiveness of the grinding wheel active surface (GWAS) depends upon the hydro-jet inclination angle and working pressure. Experimental results reveal that application of hydro-jet working pressure of 25 MPa allows for effective cleansing of the grinding wheel surface. Depending on the initial GWAS condition and the level of its smearing with chips of machined material, it is possible to increase the number of grinding wheel unevenness apexes by as much as 4.5 times.
