LTG (Long Travel Granite) series  integrates linear translation stage with a robust granite backbone, suitable for higher performance positioning over long travels.  LTG stages offer substantial cost savings, as the stage itself is an integrally supported motion system.

Product Summary

· Self-supporting Granite Back Bone Provides Ultimate Stability

· Ultra flat/straight Liner Motion Trajectory. From 0.3 to over 3 meters of Travel

· High-resolution linear encoders achieve nanometer range resolution.

· Available with a variety of drive and guide technology to meet your application

LTG Features & Benefits

Our Long Travel Granite (LTG) Positioning stage series are semi-custom products engineered to achieve the performance you require. Based on a series of standard component designs for the saddle, granite base, guides, drives and encoders a unique component is developed to satisfy the requirements of your application. Using this mix and match palate of standard components with proven and characterized behaviors we can quickly deliver LTG stages precisely matched to your positioning requirements, for excellent trajectory over long travels.

Applications

The Long Travel Granite series is a design which integrates a linear translation stage into a granite base making it suitable for higher performance precision positioning of large payloads. The Long Travel Granite stage offers substantial cost savings since the stage itself is an integral motion system which requires a minimal support with modular frames or steel weldments. A number of demanding positioning requirements in Metrology. Laser Welding, Scanning and Laser Cutting can be addressed with the LTG Series.

Extremely precise linear motion systems with a  choice of guide, drive and feedback components.

Standard Precision linear translations  made with re-circulating mechanical bearing guides to provide well controlled flatness/straightness excursions.

High Precision linear translations made with porous air bearing guides to provide exceptional flatness and straightness control.

Capable of High Positioning Accuracy, due to a choice of very high resolution encoder systems, positioning repeatability measured in the nanometer range. Standard with Linear Encoder Analogue of TTL output, optional High performance Laser Scale position feedback or the LTG can be equipped with a compact robust fiber optic delivered laser interferometer system.  

High Velocity Translation created by powerful linear motor drive form a choice of Iron core and Iron less Linear motors. Iron less Linear motors are capable of constant velocity with no detectable velocity ripple. At modest velocity Iron core motors display  velocity ripple  below 0.1%. Using advanced digital closed loop servo controls. LTG Stages have very High Payload Capacity, suitable for use moving masses up to 500kg.
