High Precision Positioning Stage for Long Travel
Tue, 06/16/2009 - 11:28am
The PMT320 model offers a repeatability of +/- 1 micron, excellent straightness, run-out accuracy, and travel distances from 600 to 1,500 mm. The stage has a 320 mm wide die cast base profile and the 1,000 mm stroke stage weighs 70 kg. This series offers two drive options, a servo linear motor or DC rotary motor with precision ground ball screw. Position feedback is provided by a linear encoder. Depending on the drive chosen, maximum acceleration of 5 m/s² and maximum speed of 500 mm/s² can be achieved. Linear guidance is provided by size 25 precision linear profile rails, which gives the PMT320 a load capacity of 500 kg. Flatness and straightness run-out is +/- 2 microns over any 100 mm travel. For harsh environments, an optional steel cover is available to protect the components.
