What is a Diamond Dresser anyway?

A diamond dresser is a tool that has one or more diamond(s) mounted on a shank by sintering. It is used to true and “dress” grinding wheels. Its hard and sharp cutting edge is used to reshape a grinding stone to be flat and to contour its porousness to affect different cutting aggression by the wheel.

Single Point Diamond Dresser

For this article, we are only going to talk about a “Single Point Diamond Dresser” which is what Kwik-Way machines utilize to dress the grinding stones. Just like the name implies, these dressers have a single diamond point on the tip of the dresser. The shaft is made of cold-rolled steel that is either smooth or finely threaded. Single point diamond dressing tools can be applied to aluminum oxide, ceramic, and silicon carbide abrasive grinding wheels. These are not intended to be used on CBN grinding wheels.

Dressing, Truing, Shaping

Firstly the idea is to “True-up” your grinding wheel. From the factory, a grinding wheel is not perfectly round. Also, because of mounting variables, your new grinding wheel is not perfectly round to the grinding spindle. The new surface of the wheel may have chips or a slight glaze that needs to be removed before its first use. When the sharpness of the grinding wheel becomes dull because of glazing and loading, the dresser diamond is used to remove dulled grains and chips. With a proper procedure and a good dressing tool you make sharp cutting edges and simultaneously, make recesses for chips by properly extruding to the grain cutting edges of the stone material. A properly dressed grinding stone will have a flat and true to the workpiece surface with open pores providing for the best possible grinding performance from the stone.

So to sum up about Dressing, the objective is to create and expose new, superficial cutting edges on the wheel. Single point diamond dressers achieve this objective by shattering existing grains and facilitating the exposure of the desired abrasive particles. Dressing must be performed regularly to maintain optimal grain protrusion and grain edge sharpness.
