Courtesy of Abrasive Technology. A diamond grinding wheel. While hard chrome is usually ground with an aluminum-oxide or silicon-carbide grinding wheel, the hardness of HVOF coatings requires that they be ground with a diamond wheel. As a result, the grinding machine requires higher static and dynamic stiffness.

Adjust the guard to be 1/16 of an inch from the wheel. By doing this, you are eliminating the chances of your tool getting caught between the guard and the wheel. If your bench grinder has a spark guard, adjust that too. It needs to be very close to the wheel, as the tool rest. Now, you need to get a dressing tool.

Grinding can be defined as the rapid removal of material from a sample either to reduce it to a suitable size or to remove large irregularities from the surface. The grinding wheel or plate typically rotates at a high speed (around 200-1000rpm) and a coarse, bonded abrasive (> 40 µm) is used. Grinding is quick and relatively easy process but can

For traverse surface grinding that alternates between upcuts and downcuts, a large step over: 50% or more, for example, may induce heat generation. A 50% step over means that 50% of the first will be ground again in the second pass, and so on. For example, if the wheel is 2" wide, the second pass will regrind 1" of the previous pass and 1 ...

Lapping, though it is an abrasive process, differs from grinding or honing because it uses a "loose" abrasive instead of bonded abrasives like grinding wheels. These abrasives are often purchased "ready mixed" in a "vehicle" often made with an oil-soap or grease base. These vehicles hold the abrasive in suspension before and during use.
