Technical Info

The importance of dressing and truing abrasive grinding wheels can never be over-emphasized. Dressing will restore the exposure and cutting ability of the abrasives on the wheel surface. Dressing must be performed after truing or whenever the wheel surface becomes loaded or glazed, or loses its cutting ability. Dressing removes the unwanted residue, such as braze and steel particles, from the wheel surface. Dressing also removes small portions of the bond material and exposes the abrasives, thus allowing for effective cutting action. Truing is the procedure for eliminating any unwanted ‘run-out’ once the wheel has been mounted. Truing is best done wet.

In general, there are four types of dressers 1) single point diamond dressers 2) multi-point diamond dressers 3) forming diamond dressers and 4) impregnated diamond dressers.

1. SDD (Single-point Diamond Dressers) This type of dresser is made by sintering a selected diamond crystal with a metal matrix in a steel shank. The point of the set diamond is concentric with the shank

2. MDD (Multi-point Diamond Dressers) This type of dresser is made by sintering two or more diamonds with a metal matrix to provide multi-diamond points for dressing larger and wider abrasive wheels. There are many advantages for multi-point diamond dressers. The multi-points allow the spreading of resistance, thus reducing frictional heat, extending tool life, reducing likelihood of early failure, and allowing for faster dressing.

3. FDD (Forming Diamond Dressers) This type of dresser is made by sintering a high quality mono-diamond crystal with a metal matrix in a steel shank, and then grinding into various shapes such as a conical point with radius, facet, or profile.

4. IDD (Impregnated Diamond Dressers) This type of dresser is made by sintering a mixture of selected diamond particles with a metal matrix. This provides a longer tool life, is very economical, and is ideal for use with larger and wider abrasive wheels. EHWA is committed to developing all kinds of diamond dressers by applying up-to-date technology for supporting our customers around the world.
