Optimal Engineering Systems releases Motorized Linear X-Axis Plus rotary positioning stages

November 19, 2018  –  Optimal Engineering Systems, Inc. (OES) has released a series of  X-axis stages with integral Rotary Positioning Stages.  The four X-and-Theta stages in this series feature linear travels of: 15 mm (0.591 in.), 30 mm (1.181 in.), 50 mm (1.968 in.) and 75 mm (2.953 in.), and the rotary table, capable of continuous 360O rotation in either direction, measures 100 mm (3.937 in.) in diameter.  A 60 mm (2.362 in.) diameter version is also available.  These X-and-Theta stages are designed for applications such as: Angular glass cutting and grinding, wafer alignment, semiconductor handling, laser cutting, drilling, machining, scanning, inspection, assembly, and testing. 

The X-axis stages move on crossed roller bearings and are driven by a 1 mm per turn precision ground lead screw at speeds up to 5 mm/sec.  Featuring 3 micron repeatability, the linear resolution of the X-axis stages are 0.5 microns (10 Micro-steps per Step Motor Driver in use) and 0.25 microns (20 Micro-steps per Step Motor Driver in use) with positional accuracy is 10 microns. 

The 100 mm diameter theta stage is driven by a 180:1 ratio worm gear.  Resolution of the theta stage is 0.001O (10 Micro-steps per Step motor driver in use).  Repeatability is 0.005O, positional accuracy is 0.01O and backlash is 0.005O.   A precise pattern of threaded holes in the table enable installation of tooling.

Two-phase stepper motors are standard.   A knob for manual adjustments on each the stepper motors can be replaced with an incremental encoder for position verification or a servo motor. These black anodized aluminum X-and-theta stages can integrate into new or existing systems.  Compatible motion controllers are available from OES and the X-plus-theta stages can also be ordered as complete plug-and-play systems.
