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.
Special feature
Options
Adjustable scale
For free selection of the zero position, the scale ring can be rotated and clamped opposite the spindle.
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 with the knob on top.
Option: spindle clamping
The optionally available KS-M4X7 clamping screw can be used to additionally secure the spindle against rotation.
