Das Diamantrollen-Abrichtgerät ist auf die speziellen Raumverhältnisse The dressing unit is designed for the specific space requirements of circular grinders. It complies with the demand for minimised dressing times.

During the tool changing process the diamond roller swings in rapid traverse mode to just in front of the grinding disc and then moves at an adjustable dressing speed over the grinding disc and subsequently away again in rapid traverse mode. This dressing movement is produced by a hydraulic cylinder. The entire dressing process is controlled by electro-hydraulic means and can be integrated into the automatic programming of the machine.

This dressing unit is mounted on the machine bed of surface grinders for grinding guide rails where the grinding spindle shaft stands vertically. The grinding wheel runs therefore horizontally.

Die sehr steife Abrichtspindel ist senkrecht angebracht, ebenso die The very rigidly mounted dressing spindle is vertical, as is the drive spindle for the roller driving motor. The radial and axial run-out deviations on the diamond roller are max. 2 μm. The axis of the dressing spindle can be adjusted very accurately in both directions.

We supply these units in two versions

a) Adjustable using tension / pressure bolts
b) Adjustable using wedges
