Function
- The slide of the positioning table can be adjusted linearly by hand by turning the control knob.
- The operator can read the slide position directly on the position indicator with an accuracy of 0.1 mm.
- The indicator can be adjusted and fixed as required relative to the spindle.
- The position indicator is available in 2 designs and can be mounted in 3 positions.
- Due to the preloaded spindle and spindle nut, no clamping is necessary after adjustment.
- The spindle can be additionally fixed in the bearing block with the clamping screw KS-M6x13. (Accessories)
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 PT8625-PA positioning stage can be easily extended with the other size 25 adjustment units to form a multi-axis system.
Special features
Variable mounting of the position indicator
The position indicator can be rotated 4 x 90° around the spindle axis and fixed. (Picture example "L" left)
Zero position freely selectable
After loosening the clamping screw, the display value can be adjusted independently of the spindle on the red adjustment ring.
Options
Numerical orientation for vertical position of the spindle
The position indicator is also available with 180° rotated (upside down) digits.
Spindle clamping
With the optionally available KS-M6X13 clamping screw, the spindle can be additionally clamped against rotation.
