ECONOMICAL X-Y BALL-SCREW STAGE FOR
Aerotech (http://www.aerotech.com) has introduced an X-Y ball-screw stage for high precision applications from surface metrology to automation. The new PlanarSL is an economical alternative for applications that do not require the ultra-high speed and precision of the recently introduced PlanarDL.
The low-profile mechanical bearing stage combines two axes of motion in a compact package. Its precision-ground and preloaded ball screw is designed to drive directly through the centers of friction and stiffness, resulting in superior geometric performance and accuracy.
High-precision linear motion guide bearings provide excellent straightness and flatness with optimal support of the moving carriage over the entire XY travel. Sructural elements have been optimized for the highest possible planar performance.
In addition to the standard 24 VDC bipolar stepper motor, options include brushless and brush DC motors with high-resolution rotary encoders preconfigured for use with Aerotech controls.
The PlanarSL is available with low-thermal expansion (3.3 ppm/˚C) precision glass linear encoder scales on both axes for high-accuracy and repeatable positioning over long periods of time.
Aerotech is a leading global supplier of positioning and motion control products for industry, government, science and research institutions. Its products provide critical performance for demanding applications requiring high precision, high-throughput motion control solutions.
