Mechanical Gantry System Provides High Speed, Precision

(Nanowerk News) PI adds to its family of precision automation sub-systems with the A-351 MGS, a compact mechanical gantry system engineered to deliver maximum throughput for applications that require controlled precise overhead motion. The gantry is driven by linear motors and each axis is equipped with preloaded linear bearings. Applications include high-precision 3D printers, assembly, pick-and-place, alignment, inspection, and other industrial automation applications.

The A-351 MGS gantry system is designed for high load capacity of 20kg, twice the amount of its A-341 air-bearing-based sibling. Absolute-measuring linear encoders with nanometer resolution are optional, rendering homing procedures unnecessary and ironless linear motors eliminate cogging, providing smoother motion without vibration and better velocity control.

Vertical Axis

An optional vertical axis (Z-stage) with either ballscrew drive or linear motor and pneumatic counterbalance can be integrated with the gantry cross axis.

Features of the ball bearings stages include:

  • –300x300 to 500x1000mm XY travel
  • –Absolute encoders, 1nm resolution
  • –Z-Stage options: linear motors or ball screws
  • –Dynamic error mapping
  • –2m/sec max velocity (cross axis)
  • –Cable carrier option, e-chain
  • –Water cooling option for high acceleration / high duty cycle applications
  • Industry-Leading Motion Controllers

    The MGS Gantry can be run with industry-leading ACS motion controllers and drives that offer superior servo performance, advanced control algorithms to improve dynamic performance and error compensation specifically for gantries, and a wide suite of software development tools.
