Precise preparation, including dressing and balancing, ensures the correct geometry of the grinding wheel mounted on its wheel arbor, the condition of its abrasive surface and its stability during operation. Inadequate preparation, on the other hand, can increase grinding forces, cause vibration or heat generation, and directly affect accuracy and the surface finish of the workpiece. Even a grinding wheel perfectly matched to the application cannot deliver its full performance without proper preparation.
With the ASA 300W, diamond and CBN grinding wheels are dressed and profiled with very high precision directly on the complete wheel pack. This preparation is carried out independently of the production machine, which therefore remains available for grinding.
To ensure suitable dressing for different grinding wheel specifications, we recommend having at least two types of dressing wheels available.
For grit sizes from 10 to 35, the recommended specification is 80C 500 I7 V62A.
For grit sizes from 46 to 252, the recommended specification is 10C 120 KL7V.
The following dressing wheels are recommended by ASA and kept in stock, available individually.
| Grit size | Specification | Manufacturer |
| 1 to 10 | SC9-1000-J12 RE DM | Atlantic GmbH |
| 15 to 25 | 80C 500 I7 V62A | Stella Keramik GmbH |
| 30 to 46 | 10C 320 KL7V | Comet Schleiftechnik GmbH |
| 54 to 76 | 10C 220 KL7V | Comet Schleiftechnik GmbH |
| 91 to 107 | 10C 120 KL7V | Comet Schleiftechnik GmbH |
| 126 to 252 | 10C 60 KL7V | Comet Schleiftechnik GmbH |
Large diameter or thin abrasive layer = reduce the feed rate.
Small diameter or thick abrasive layer = increase the feed rate.
Example: For a grinding wheel diameter of 150 mm and an abrasive layer thickness of 3 mm, the feed rate is approximately 0.5 m/min.
After dressing, the surface of the abrasive layer may remain dull. To achieve optimum cutting ability, we recommend manually opening the grinding wheel with a sharpening stick. The stick should be wetted with oil and applied with the grinding wheel rotating in its normal working direction and at its operating speed.

This is where we develop and manufacture our diamond and CBN grinding wheels, as well as our machines.
Our grinding wheels are manufactured in our own workshops, from the preparation of the compositions and forming to pressing, machining, dressing and quality control.
Our machines are developed, assembled and tested in Cornaux, with many components manufactured directly by ASA.
For more than 30 years, we have been cultivating industrial expertise in Switzerland, built on complete control of our processes, precision and quality.
