High load, low profile XY stage features high resolution

A new, larger, high load, precision stage, has been added by OES (Optimal-Engineering Systems), to its extensive line of precision XY stages. The AU200-170x170 stage is a low profile stage measuring just 108mm high with a compact footprint (including the motors) of 458.5x458.5mm. 

The linear travel of the X and Y axes is 170x170mm, and the resolution of each axis is 20μm (non-micro-step) or one micron (20 micro-steps per step motor driver in use), repeatability is two microns, and the positional accuracy is three microns. 

The four millimetre per-turn lead screws have just two microns of backlash and the stages have preloaded V-groove and crossed roller bearings contributing to the high precision and stiffness of the AU200-170x170 Stage. Designed for applications such as: alignment, assembly, laser drilling, machining, medical, industrial, semiconductor handling, testing, scanning, and optical applications, this compact, low profile black anodised aluminium XY stage is easy to integrate into new or existing systems. 

The XY stage's table measures 300x300mm and features a precision pattern of drilled and threaded mounting holes to facilitate the addition of tooling or fixtures. Additionally a table with a large open aperture is also available. 

The standard two-phase (1.8°) stepper motors have knobs for manual adjustments of each axis of the stage, however, the knobs can be replaced with incremental encoders for position verification or closed loop operation. As an option, servo motors and compatible motion controllers are also available from OES, or the AU200-170x170 Stage can be ordered as a complete plug-and-play motion control system.
