Function
- The slide of the positioning table can be adjusted linearly by turning the scale knob by hand.
- One graduation mark of the scale knob corresponds to 0.05 mm of adjustment travel.
- The scale ring can be adjusted relative to the spindle.
Due to the preloaded spindle and spindle nut, no clamping is necessary after adjustment. - The spindle can be additionally fixed on the bearing block in the D5 thread with the KS-M4X7 clamping screw.
Advantages
No backlash
Spindle nut and spindle bearing are preloaded. This allows the slide to be positioned from either direction without backlash.
Self-locking spindle
Due to the preload, the control knob offers some resistance when turning. This means that the carriage always holds its position securely.
Modular system
The PT7312 positioning stage can be easily combined with all size 12 adjustment units.

Scale knob
Adjustable scale
To zero in the dial, the scale ring can be rotated and clamped.
Option: Number orientation for vertical spindle position
The scale knob is also available with the digits turned 180° (upside down).
Here the digits are readable with the spindle in vertical position.
Option: Spindle clamping
The optionally available KS-M4X7 clamping screw can be used to additionally secure the spindle against unwanted manipulation.
Mechanical position indicator PA
Mechanical counter
The operator can read the slide position directly on the position indicator with an accuracy of 0.1 mm.
After loosening the clamping screw, the red ring can be rotated to adjust the display indication.
Variable alignment of the position indicator
The position indicator can be rotated 4 x 90° around the spindle axis and fixed. (Picture example "L" left)
Upside down digits (PA/PAE)
The position indicator is also available with 180° rotated (upside down) digits.
Elektronic position indicator PAE
multifunctional position indicator
Reset-, incremental measurement- and offset-button
Large LCD display
Battery life 2 years
Easy battery change without loss of settings
Variable alignment of the position indicator
The position indicator can be rotated 4 x 90° around the spindle axis and fixed. (Picture example "O" over the top)
Hand crank instead of rotary knob (PA/PAE)
For more speedy adjustments, order a handwheel.
Locking lever
Clamping of the carriage on the guide rods
The carriage can be clamped directly to the two guides with two clamping levers.
After pulling the clamping lever axially, it can be disengaged and swivelled into any position. Once released, it engages again by spring pressure.
