Roll measuring devices used either during grinding on the grinding machine or for offline measurement complete the Vollmer product spectrum for cold rolling.
Vollmer offers VSL/VSS systems for fully automatic roll measurement during dressing on the grinding machine, and traversable straddle gauges which are placed onto the roll for offline measurement.
The gauges from the VSL/VSS Series measure the form, diameter, roundness and eccentricity of the rolls during the grinding process with very high precision. Form, radial run-out and eccentricity are measures with a precision of ± 1 µm.
If an interface is available, they communicate online with the controller of the roll grinding machine and thus enable even more cost-effective use of the grinding machine.
With the appropriate configuration, they measure the height and lateral alignment of the roll in the grinding machine before grinding, often enabling the set-up time to be significantly reduced.
Vollmer produces the automatic roll measuring gauges for both bench-mounted machines where the roll is moved along the grinding wheel and for support machines where the grinding wheel is moved along the rotating roll. Vollmer supplies the systems for a broad spectrum of roll diameters.
