In such the normal type as this, the cutting edge intervals (from original sharpness to next sharpness) of abrasive grains are adequately kept, grinding wheel wear is remarkably less in comparison with the shedding type since chips are not welded. Consequently, the workpiece surface is finely finished and grinding precision.

Grinding Wheel Glossary : Mach-B Minnesota

Jun 9, 2014 . A thin layer of abrasive is applied to the pliable perimeter of the cloth wheel using a compound that can be applied as a liquid or solid. For wax-based compounds, heat generated by friction melts the wax, exposes the abrasive grains and provides an adhesive to keep the abrasive in place. There are stages.

Product introduction | SHIN-EI Grinding Wheels MFG. Co.,Ltd.

We consider resinoid bond to be the optimal bonding agent for affixing fine abrasive grains, because it enables more uniform dispersion of abrasive grains in comparison to other bonds. Building upon these ideas, SHIN-EI GRINDING WHEELS MFG. CO., LTD. has developed and manufactured high speed roll grinding.
