The solid base guarantees an excellent stability. The high-precision column features a hard, glassy bearing surface which enables the slide to glide smoothly. The measuring slide has a special slide bearing on the front as well as roller bearings on the side. The surface pressure and therefore the gliding property can be adjusted very easily according to individual requirements.

Calibration Set for Knife-Edge Squares

Kunz precision presents a simple but unique solution for measuring knife-edge squares: Hereby the new developed lever gauge GT 31-TK is employed. The measuring probe shows a cylindrical touching surface with two markings in between which the test piece is being probed. In this way, the inner and outer leg of the test piece can be measured quickly and straightforward.



SQUARE-tool is an ingenious device for even faster and more efficient measurements, with vacuum exhaust. The positioning aid is used together with the squareness measuring devices SQUARE-line, SQUARE-plus, SQUARE-control and SQUARE-master.


Measuring Probe Mounting SQUARE

This measuring probe mounting allows to measure inner surfaces with the squareness measuring instruments SQUARE-line and SQUARE-plus in the simplest way. This simple and practical accessory consists of a temperature insensitive extension tube of aluminium or carbon fiber and a probe holder.


Measuring Probes

We have several probes in our range.



Developed as an efficient software-programme to calibrate reference angles and straight edges, STRAIGHT-soft is an indispensable aid in the measuring laboratory, the workshop or when carrying out measurements on geometry during acceptance of machinery. For testing straightness, parallelism and squareness.
