The model PMT320 offers a repeatability of +/- 1 micron, excellent straightness run-out accuracy and travel distances from 600 to 1500 mm. The stage has a 320 mm wide die cast base profile and the 1000 mm stroke stage weighs 70 kg.
Drive options are 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/s‚² and maximum speed of 500 mm/s‚² 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.
