Caution!
For the 2nd Axis an additionial positioning Table (or vertical lift stage) is required.
Function
- The Long Cross Table Base is derived of the short positioning table.
- Cross table bases show a bigger, flatter slide, witch is prepared for mounting a positioning table directly on it.
- A cross table KR and KL can be combined with a short positioning table.
- A cross table L can be combined with a long positioning table or a vertical lift stage.
Advantages
low height
Due to the modified slide, an additional positioning tabe can be mounted directly, without further parts. The design is very compact.
Modular system
The KT7312 long cross table base can be easily combined with all size 12 adjustment units.
Assets of MM-Engineering linear manual actuators:
backlash free
Spindle nut and spindle bearing are preloaded. This allows the slide to be positioned from either direction without backlash.
Self-locking spindle
Metric threads are essentially self-locking. Due to the preload, the control knob offers some resistance when turning. This means that the carriage always holds its position securely.
column guides
The linear stages' column guides consist of high-alloyed steel shafts and brass bushings.

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.
