There are several ways of checking straightness, but most of them are so complex and involve so much outlay that operators have to be highly qualified.



For fast and easy straightness measurement to the highest precision, Kunz precision has developed the STRAIGHT-line measuring slide. The special feature of this innovative product is its vacuum air-bearing system.

The STRAIGHT-line slide is held by vacuum against the guideways, but direct contact is at the same time prevented by air-bearings. This ensures stable and practically invariable prestressing. The STRAIGHT-line slide is operated from the local compressed air network via an air unit. The best guideway materials are hard stone or ceramic, which can be finished to the highest precision.

Als Thanks to this sophisticated vacuum air-bearing system, the STRAIGHT-line mea-suring slide requires only two guideway surfaces, one horizontal and one lateral. Measurement accuracy largely depends on the precision of these two surfaces. The side plate of the STRAIGHT-line slide is fitted with bearings matching the lateral guideway surface. Not only does this enhance measuring precision, but it significantly reduces guideway production costs.

Since only two guideways are required, completely new possibilities are opened up. For example a test plate with machined lateral guide surface can be used. The high resistance of the lateral guideway to thermal distortion guarantees the highest possible precision under workshop conditions.

With two machined lateral guideway surfaces, high-precision squareness mea-surements can be carried out quickly and reliably.

STRAIGHT-line can be automated to various degrees. The simplest and most cost-effective version is with friction gear drive, but fully automated versions are available complete with control system.
