Z-Lift and Vertical Axis

Description

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. Data sheet.

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.

MECHANICAL BEARING Z STAGE

The advantage of this family of vertical Z-lift stages:

  • Linear or voice coil motors
  • High rigidity crossed roller bearings
  • High force motors
  • Linear encoders
  • Air counter balanced
  • Motor, bearings, encoder and counterbalance all on approximate centerline of the stage
  • Payload can mount directly to the face or top surface of the stage to eliminate the weakness and resonant frequency issues associated with additional brackets
  • Excellent dynamic performance

COMPACT VOICE COIL Z STAGE

The advantage of this family of vertical Z-lift stages:

  • Compact design, low profile height
  • Voice coil motors
  • High rigidity crossed roller bearings
  • Linear encoders
  • Air counter balanced
  • Motor, bearings, encoder and counterbalance all on approximate centerline of the stage.
  • Payload can mount directly to the face or top surface of the stage to eliminate the weakness and resonant frequency issues associated with additional brackets
  • 4X to 10X more precise than Z-wedge stages.

GEOSYMMETRIC™ Z STAGE, LINEAR MOTOR DRIVE WITH MAGNETIC COUNTERBALANCE

The advantage of this family of vertical Z-lift stages:

  • Sturdy design minimizing Abbé errors
  • DC Servo Linear Motors
  • High rigidity crossed roller bearings
  • Linear encoders
  • Motor, bearings, encoder and counterbalance all on approximate centerline of the stage.
  • Payload can mount directly to the face or top surface of the stage to eliminate the weakness and resonant frequency issues associated with additional brackets
  • 4X to 10X more precise than Z-wedge stages

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.

AIR BEARING LINEAR MOTOR Z STAGES

The advantage of this family of vertical linear stages:

  • Granite base to ensure exceptional flatness and straightness.
  • Linear servo motors
  • High rigidity, nano-precision air 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
  • Counterbalance brackets can be changed if required to assure counterbalance force is transferred through the mass center of the load.
  • Motor, bearings, encoder and counterbalance all on approximate centerline of the stage

LINEAR MOTOR MAGNETIC COUNTER BALANCED Z STAGE FOR HIGH FREQUENCY AND QUICK FOCUS

The advantage of this family of vertical linear stages:

  • ALIO’s nano-precision design
  • Linear servo motors
  • High rigidity crossed roller bearings
  • Linear encoders
  • Removes the need for air lines to counter balance and can be designed for motion AWAY from crashing on a power-off situation
  • Motor, bearings, encoder and counterbalance all on approximate centerline of the stage.
