Steinmeyer-FMD’s new precision, multi-axis air bearing gantry system incorporates a high-performance TONiC optical incremental encoder from Renishaw Oceania to ensure both speed and accuracy.  

The new air bearing linear axis and gantry system introduced by the precision engineering and precision optics company, Steinmeyer-FMD is designed for applications requiring ultra-high precision and outstanding dynamic performance.  

These new air bearing gantry systems find application in laser machines, dispensing systems, inspection systems, ‘pick and place’ machines and gene chip production equipment.  

Steinmeyer-FMD’s new motion system consists of an XY stage utilising air bearings and a conventional ball screw driven Z table, with the TONiC optical linear encoder providing incremental position feedback on all the linear axes.  

The motor concept is based on a wear-and-noise-less drive operating at very high speeds. Depending on the application, the XYZ design can be complemented with A- and B-axes and adapted to the required load, speed and accuracy.  

Smooth velocity control is achieved as the TONiC optical incremental encoders incorporate dynamic signal processing within the readhead, providing an ultra-low Sub-Divisional Error (SDE) for improved signal purity.  

The reduced jitter of just 0.5 nm RMS and finer resolution result in an encoder that provides significantly improved positional stability and excellent low-speed velocity control.  

Long-term operational reliability is further assured with the TONiC encoder’s proven filtering optics, which are now enhanced by Auto Gain Control (AGC) for rugged signals that can withstand dust, scratches and light oils on the scale.  

Key features of Renishaw’s TONiC optical incremental encoder 

  • Super-compact construction
  • Available with a variety of high-accuracy linear and rotary scales
  • New 1 nm and 2 nm resolution versions also available
  • Incremental encoders offer all the benefits of a 20 micron pitch encoder such as easy set-up, low cost of ownership and superior dirt immunity while providing resolution and noise levels of much finer pitch encoders
  • Reduced jitter of just 0.5 nm RMS

TONiC incremental encoders are backed by a truly responsive global sales and support network. Additionally, the encoders meet the highest environmental standards with both WEEE and RoHS compliance.
