V8 Piezo-Walk Technology Powers Vacuum Compatible Nanopositioning Stage, new from PI

UHV option is ideal for applications in semiconductor and beamline research. The compact design facilitates the integration of the new N-332 linear positioner.

PI's new N-332 nanometer-precision linear stage family, configurable to multi-axis setups of XY, XZ and XYZ, is designed for high-end applications in semiconductor technology, fiber-optics, microscopy, bio-nanotechnology, metrology and scientific research in beamlines and laser labs. The stages have a low profile of 30mm and a small footprint of 80x110mm an 80x160mm with travel ranges of 1" and 2", respectively.


No Brake or Counterbalance Required
Due to the high active force of 75N and power-off passive holding force of 80N, the N-332 nanopositioning stage does not require a brake or counterbalance when operated in vertical orientation.

UHV-Option
For demanding applications that require operation in high vacuum, N-332 stages are available in configurations suitable for pressures down to 10-9 hPa. The self-clamping nature of the piezo motor allows the stage to hold a position without heat generation.

PICMA-Walk Technology - High Force and High Resolution
The PICMA-Walk piezo motor inside the N-332 stage is based on 4 pairs of PI's proprietary PICMA® piezo actuators, arranged in a V8 configuration. PICMA® piezo actuators were successfully tested for 100 billion cycles by NASA/JPL before being used on the Mars Rover's instrumentation lab. PICMA-Walk motors provide high force linear motion to 75N and are capable of sub-nanometer resolution and self-locking when de-energized - a great advantage for applications where a stable position must be maintained without power, heat generation or servo jitter.

T.J. Davies' Retention Knobs

Our retention knobs are manufactured above international standards or to machine builder specifications. Retention knobs are manufactured utilizing AMS-6274/AISI-8620 alloy steel drawn in the United States. Threads are single-pointed on our lathes while manufacturing all other retention knob features to ensure high concentricity. Our process ensures that our threads are balanced (lead in/lead out at 180 degrees.) Each retention knob is carburized (hardened) to 58-62HRC, and case depth is .020-.030. Core hardness 40HRC. Each retention knob is coated utilizing a hot black oxide coating to military specifications. Our retention knobs are 100% covered in black oxide to prevent rust. All retention knob surfaces (not just mating surfaces) have a precision finish of 32 RMA micro or better: ISO grade 6N. Each retention knob is magnetic particle tested and tested at 2.5 times the pulling force of the drawbar. Certifications are maintained for each step in the manufacturing process for traceability.
