grade grinding stone. After grinding or machining, we recommend the following roughness values: l l /20 à l /10! Roughness values exceeding 2 µm cause high brush wear. The aim of the grinding operation is to obtain the correct number of 100 peaks / cm. l • Check that bar edges are properly chamfered (see Technical Data Sheet TDS-03)
Grinding wheels made with a vitrified bond are extremely strong, but rigid. This means that using them for rough work, as you would with a resin bond, is not a good idea. It is more common to find a vitrified bond with diamond grains than CBN, but this combination is still effective for grinding things like alloy steels.
Grinding wheels are used to generate the desired profile of gear teeth after heat treatment. The machine and gear type determine the shape of the grinding wheel. Continuous gear generation, profile grinding, bevel gear grinding, and power honing are the most common grinding processes in gear manufacture.
After all, it doesn't matter how mind-bogglingly fast upstream processes are if it takes forever and a day for parts to make it through the grinding department.

Whereas chrome plating applies a positive current to a chrome solution - which adheres chrome molecules to the surface of the steel, reverse electrolysis does the opposite. A negative current is applied to the solution and chrome molecules separate from the surface - thereby stripping the old chrome away. Stone Grinding:
Grinding with Rösler: Perfectly prepared surfaces. Surface defects, mold release seams on components, die-cast surfaces, grinding grooves or roughness from additive manufacturing methods (3D printing) and other manufacturing processes need uniform, finely structured surfaces for further use or refining. Rösler mass finishing processes create ...
Any patch/repair work to be done should be done AFTER grinding with 30 grit at least once and should be finished up with a 30 grit grind after patch work (to blend with surface).
