Aerotech Offers XY Ball-Screw Stage
Aerotech’s PlanarSL mechanical bearing, ball-screw-driven XY stages combines two axes of motion in a compact package, the PlanarSL is suitable for applications ranging from surface metrology to general high-precision automation.
The PlanarSL comes standard with a precision-ground and preloaded ball screw. Unlike competitive designs where the ball screw is positioned on the side or off-center, the PlanarSL ball screw is engineered to drive directly through the centers of friction and stiffness, resulting in superior geometric performance and accuracy.
High-precision linear motion guide bearings provide straightness and flatness with optimal support of the moving carriage over the entire XY travel. The PlanarSL structural elements have been optimized for the highest possible planar performance.
Unlike competitive designs using steel (13 ppm/˚C) or glass scales with 8 ppm/˚C thermal expansion coefficients, the PlanarSL is available with low-thermal expansion (3.3 ppm/˚C) precision glass scales on both axes for high-accuracy and repeatable positioning over long periods of time. The linear encoder, available with amplified sine (1 Vpp) or 0.1 µm TTL digital outputs, is mounted near the centers of action, again providing an optimized stage design for high-accuracy positioning.
The PlanarSL comes with a 24 VDC bipolar stepper motor. Aerotech can also provide brushless and brush DC motors with high-resolution rotary encoders preconfigured for use with Aerotech controls. A wide selection of state-of-the-art motion controllers is available, along with a suite of software and drive electronics, to provide cost and performance options to meet the needs of any application.
