Precision stages boost accuracy

A PI (Physik Instrumente) product story
Edited by the Engineeringtalk editorial team Aug 24, 2007

M-122 stages can be driven with the low-cost, networkable, C-862 Mercury servomotor controller/driver.

PI has released the M-122 palm-top-sized precision translation stage which combines compact dimensions, high dynamics and speed and very high accuracy at a competitive price.

Typical applications include metrology, quality assurance, testing equipment, micromachining, photonics packaging and fibre positioning.

The M-122 features a space-saving, folded drive train with the servomotor and drive screw side-by-side.

Equipped with a noncontacting optical linear encoder and a preloaded, precision-ground, ball-screw, these stages can provide much higher accuracy, better repeatability and dynamic performance than conventional stepper motor stages or rotary encoder-equipped servomotor stages.

M-122 stages can be driven with the low-cost, networkable, C-862 Mercury servomotor controller/driver.

For multi-axis applications, the C-843 PC Board is available.

M-122 stages can be combined with very compact XY and XYZ systems.

Due to its low-friction, the backlash-free ball screw yields significantly higher mechanical efficiency than leadscrews, and allows maintenance-free, high duty-cycle operation at high velocities up to 20mm/sec.
