OES Expands Series of Positioning Stages

High precision motorized cross roller XZ dual-axis linear stages

High precision motorized cross roller XZ dual-axis linear stages

September 22, 2021—
Optimal Engineering Systems, Inc. (OES) is offering a new series of high precision, low profile, low cost motorized Dual-axis XZ Positioning Stages. The compact XZ110 Dual-axis Linear Stages are available with X axis and Z axis travel lengths of 15 mm (0.590 in), 30 mm (1.181 in), 50 mm (1.968 in), and 75 mm (2.952 in) that can be ordered in any combination. Precision ground lead screws with only 2 microns of backlash and high precision cross roller linear travel guides assure repeatability of 3 microns, and positional accuracy of 10 microns. Open loop resolution of each stepper motor driven axis (shown) is 0.5 microns using a 10 mirco-steps-per-step stepper motor driver. However, even greater precision and higher travel speeds can be achieved with the selection of either a Three-Phase Brushless Servo Motor or DC Brush Servo Motor.

Table sizes by travel length are: 15 mm travel length is 65 mm x 65 mm (2.559 in x 2.559 in), 30 mm is 90 mm x 90 mm (3.543 in x 3.543 in), 50 mm is 90 mm x 110 mm (3.543 in x 4.331 in), 75 mm is 90 mm x 110 mm (3.543 in x 4.331 in). Each of the tables has a precision pattern of 16 threaded mounting holes for the addition of custom tooling. The base has drilled and countersunk holes for easy integration into new and existing applications. 

The knob on the back of the stepper motors for manual adjustments can be replaced with an incremental encoder for position verification. Each stage includes limit switches that should be used to avoid over-travelling.

Additionally, any of XZ110 Series of Linear Positioning Stages can be ordered as a complete Plug-and-Play system with fully compatible multi-axis motion controllers.
