Dover gantry stages are designed to provide unsurpassed repeatability and excellent throughput under real world operating conditions. Our gantry stages are designed to move such items as inspection cameras, laser heads, or specific customer tooling over either removable substrates or fixtures mounted to the base of the system. The gantry base can be provided with mounting holes for interfacing a customer’s hardware to the stage. Due to its simplicity and ease of assembly, it is the ideal gantry stage configuration for OEMs and system integrators building machines for demanding applications. Many of Dover Motion’s standard screw driven and servo motor linear products can be integrated together as a gantry stage to achieve an application’s required accuracy and travel for XYZ motion.

  • Pre-formatted base for ease of integration
  • Risers to provide space between the base and moving beam
  • Integrated cable tracks and hi flex cable
  • All axes tested together and burned in to ensure performance and reliability requirements are met before shipment

The example shown above is run by stepper motors and controlled by the Dover Motion multi-axis stepper controller. Incorporating linear encoder feedback and cabling, it achieves 15 to 300 millimeters of XYZ linear motion travel.

Popular applications for gantry stages include:

  • 3D metrology
  • Inspection
  • Probing
  • Pick and place
  • Laser machining
  • Laser scribing and marking

Dover controllers and external cabling are available to create a complete turn-key motion system for gantries. Our controllers have coordinated motion capabilities for accurate multi-axis lines, arcs, and circles. Optional rotary or linear encoders are available to improve accuracy and repeatability. For the most accurate positioning requirements, two-point and multi-point compensation can be programmed for each axis. Dover Motion’s control options include an intuitive user interface and three-axis joysticks are available for control of the XYZ axes.
