Superfinishing, also known as micromachining, microfinishing, and short-stroke honing, is a metalworking process that improves surface finish and workpiece geometry. This is achieved by removing just the thin amorphous surface layer left by the last process with an abrasive stone or tape; this layer is usually about 1 μm in magnitude. Superfinishing, unlike polishing which …

The term "grinding burn" refers to a form of thermal damage to the part caused by an improperly handled grinding process during which too much process energy in the form of heat is channelled into the part. Due to such thermal overload during grinding, the part is mostly rendered useless, as microcracks may have been generated, for example.

High-speed grinding creates high temperatures in the grinding zone, causing the super abrasive particles to heat. Unlike diamond, however, CBN has a higher thermal resistance. In fact, at temperatures exceeding 800 degrees, CBN becomes harder than diamond and cBN is more than able to keep its cutting edge well up to 1000 degrees.

As with any high friction grinding process, you need a coolant that will help keep the grinding area clear of debris and protect against heat buildup and chemical reactions. If you decide to use a CBN abrasive wheel then look for an oil-based fluid. Water-based lubricant has a low vaporization point.

Fine Grinding (flat parts – single or double-side) is the abrasive machining process for removing material using a bonded Superabrasive wheel at low speed with a liquid to keep the part cool. The fixed grain of a geometrically indefinable cutting shape acts like a plow (fig. 3) and material is removed by micro-grooving /-cutting (fig. 4).
