. the uses of each type of wheel dressers

The wheel dressers used for off hand grinders are star wheel dressers (Huntington type wheel dresser) and diamond dressers.

The star wheel dresser consists of a number  of hardened star-shaped wheels mounted on a spindle at one end and a handle at the other end.

While dressing, the  star wheel is pressed against the face of the revolving grinding wheel. Thhe star wheel revolves and digs into the surface of the grinding wheel. This relaases the wheel loading and dull grains, exposing sharp new abrasive grains.

Star wheels are useful for pedestal grinders in which a precision finish is not expected.

Star wheel dressers should be used only on wheels which are large enough to take the load.

Diamond dressers

Bench type off hand grinders used for sharpening cutting tools are usually fitted with similar and rather delicate wheels.

These wheels are dressed and trued with diamond dressers.

Diamond dressers consist of a small diamond mounted on a holder which can be held rigidly on the work rest

How to use a wheel dresser

For dressing and truing, the dresser is slowly brought in contact with the wheel face and moved across.

The finish obtained depends on the rate at which the dresser is moved across the face.for roughing, the dressser is moved faster. For fine finish,the dresser is moved slowly.


Roughing will be efficient with a dresser that has a sharp poin, while, for the line finishing, a blunt diamond dresser is more suitable.

Abrasive stick

When only a light dressing is required, abrasive sticks can also be used. There are abrasive materials made in the form of sticks for the convenience of handling.

Diamond dressers, if moved too slowly, can glaze the wheel
