Latest Linear X-Axis Plus Rotary Positioning Stages are Equipped with Two-Phase Stepper Motors

Press Release Summary:

The Motorized Linear X-Axis and Theta Rotary Positioning Stages offer linear travels of 15, 30, 50 and 75 mm. The Theta stage features 100 mm diameter rotary table that is capable of rotating 360 degree in either direction. The X-stages offer a repeatability of 3 micron, resolution of 0.5 microns and positional accuracy of 10 microns whereas the Theta stages 0.005° (repeatability), 0.01° (positional accuracy) and 0.005° (backlash). The stages are suitable for applications like angular glass cutting and grinding, laser cutting, drilling, machining, scanning and inspection.


Original Press Release:

Motorized Linear X-Axis Plus Rotary Positioning Stages are Available from OES!

Van Nuys, CA – Optimal Engineering Systems, Inc. (OES) has released a new series of high precision 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 360 O rotation in either direction, measures 100 mm (3.937 in.) in diameter. A 60 mm (2.362 in.) diameter version is also available. These high resolution, high repeatability X-and-Theta stages are ideal 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 high precision 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 precision 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 easy 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 compact, black anodized aluminum X-and-theta stages are easy to 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.
