Spindle Test Machine STM

The spindle testing machine of Kunz precision AG allows to measure threaded spindles of different dimensions very efficiently and with highest accuracy.
The basis of the spindle testing machine is a high-precision hard stone. This acts as a support for prisms, in which the spindle is held. In addition, the guidance for the vacuum air-bearing traverse slide is integrated in the surface.

The immersion axis mounted on the traverse slide moves with a probe into the thread of the threaded spindle. The measuring slide with the special vacuum air bearing traces the contour exactly. Just above the spindle, a laser interferometer is mounted, which detects the longitudinal position with very high accuracy.
