With the slide widths of 30, 50, 80 and 120 millimeters, the user is very flexible. For the smallest version, for example, four different strokes from five to 20 millimeters are available from stock, and the largest from 25 to 100 millimeters. Other strokes can also be implemented according to customer requirements. The spindle pitches for the individual sizes are between 0.5 and two millimeters. Measurement systems, such as the camera mentioned at the beginning, can thus be set in any possible position. The user can position each slide exactly by hand and fix it from the side with a clamping lever. The slide can also be clamped directly to the spindle.
