Grinding machines - Import export

The gauges from the VSL 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.

The traversable straddle gauges are used for offline measurement. They are placed onto the roll and moved manually, thereby measuring the form of the rolls from crown edge to crown edge. They are characterised by a high measurement point density of 1 mm and a high repetition accuracy of ± 2 µm. With the evaluation software optimised over decades together with our customers for this application, curves can be pivoted and superimposed, centered and smoothed. The scope of supply also includes a panel PC.

This how each cut is made Sheet metal is available in a very wide range of materials and alloys. The criterion for machining is a given toughness and strength to make the metal sheets deformable. A part of sheet metal machining is separation by shearing, in which the sheets are divided by two shearing knives. For over 40 years, we have supplied shearing knives in lengths up to 4,190 mm in qualities and hardnesses specially matched to the purpose for the corresponding machines. By using peripheral grinding machines, we can comply with the tightest form and position tolerances, which is why so many machine manufacturers rely on the quality of our shearing knives.
