Depending on the application, JAT develops linear axis systems, rotary table systems and multi-axis systems. Please specify your application as far as you know it. Our drive experts will contact you with possible solutions and a cost estimate.

The solution in detail

Description Requirements Specification

X-ray pick-and-place stations rely on a clear light path and micron precision.
The Transmitted-Light Cross Table with Spindle Axes provides both, guiding loads up to 10 kg across 560 mm × 440 mm strokes while holding ±1 µm repeatability. Its ultra-flat frame maximises the through-light aperture, so detectors capture every detail without obstruction. Recirculating ball-screw drives deliver smooth thrust at 1 m/s, and encoders read 0.5 µm steps, giving process engineers rock-solid accuracy shift after shift.

Demands

Large transmitted-light opening for full-field imaging
Extremely low overall height to fit tight cabinet spaces
Absolute and repeat accuracy within the single-micron range
10 kg payload capacity without deflection
Plug-and-play delivery for rapid commissioning

Implementation

Self-rigid aluminium frame with maximised clear aperture
Precision ball-screws 15 × 30 (X) and 15 × 20 (Y) for high thrust
Linear scales provide 0.5 µm feedback resolution
Ball-chain rail guides ensure smooth, backlash-free travel
Welded steel base absorbs vibration and simplifies mounting

Overall system:

Load: 10 kg
Resolution measuring system: 0,5 μm
Reproducibility: 1,0 μm
Repeatability height/side: ±150 µm / ±50 µm
