Z-Lift and Vertical Axis

Z-Lift motion platforms were created to replace the inaccuracies of the ever present Z-Wedge vertical stages as well as reduce the footprint and improve performance of linear stages mounted in the vertical orientation. Every component in a motion stage adds to the total error. Since Z-wedges have a minimum of three machined components with complex angles, three sets of bearings, a motor via a coupling and an encoder, the result is a very inaccurate stage.

Z-Lift and Vertical Axis - PATENTED NANO Z Alio

PATENTED NANO Z®

Increased demands for True NANO® metrology and process lead ALIO to design and manufacture the NANO Z® patent pending Z lift air bearing stage to exceed all past design issues of tip and tilt while increasing the accuracy to less than 100 nanometers with standard Renishaw Invar encoders.[/vc_column_text][vc_column_text]MECHANICAL BEARING Z STAGE

Z-Lift and Vertical Axis - Zlift 272x300

LINEAR MOTOR COUNTER BALANCED Z STAGE

The advantage of this family of vertical linear stages:

  • ALIO’s nano-precision design
  • Linear servo motors
  • High rigidity crossed roller bearings
  • Linear encoders
  • Counter balanced with dual frictionless cylinders balancing the load. The cylinders are in-line with the motor, bearings and encoder thus they do not create an Abbé error
  • Motor, bearings, encoder and counterbalance all on approximate centerline of the stage.
