NEW Low Profile Rotary Air Bearing Stages Debut at LAM/LME on March 27-28 in Shaumburg, IL

PI's most recent rotary air bearing stages deliver a virtually unlimited lifetime of superior accuracy in a package only 60mm tall. The new A-635/A-637 PIglide low-profile stages have no rolling or sliding elements and deliver frictionless, non-contact motion, resulting in negligible reversal error, better wobble, eccentricity and velocity stability - ideal prerequisites for high-end industrial applications such as inspection, metrology, calibration, and scanning, including cleanroom environments.

  • Table Diameters 200mm & 300mm
  • 60mm Tall
  • 50kg Max Payload
  • Geometric Performance: 50nm Flatness, ±50nm Radial Runout, 1µrad Wobble
  • Vertical or Horizontal Mounting
  • Direct Drive Brushless Torque Motor
  • Optical Encoder

What is the Difference between a Piezo Actuator and a Programmable Piezo Shim?

Piezo stack actuators provide high dynamics, but can also be used for quasi-static applications due to their high-stiffness and stability given the relatively simple operating principle of extension of the stack changes roughly proportional to the drive voltage, with typical strain on the order of 0.1% of the stack's length available. Charging and discharging of a piezo actuator is related to charging and discharging an electric capacitor. Programmable piezo shims is a new technology, also based on the piezo effect, which can be utilized in situations where high resolution and stability are crucial, but a continuous drive voltage is unwanted and accessibility for manual adjustment is not possible.

NEW 6-Axis Controller for Parallel Manipulators

Just released, the C-886.31 controller is for use with PI's miniature 6-axis piezo hexapods based on Q-Motion inertia drives. Position input is easy using Cartesian coordinates as the controller takes care of all the coordinate transformation for the parallel kinematics motion system. A user programmable virtual pivot point makes alignment processes more flexible. The C-886.31 is equipped with its own data recorder and macro programming allows for stand-alone operation.
