Overview

The A-341 PIglide HGS hybrid gantry was developed for applications that require overhead motion and long travel ranges.

The A-341 hybrid gantry has a unique hybrid guide design. The bridge axis is equipped with a friction-free guide with air bearings that allow exact control of velocity as well as outstanding repeatability and straightness. The guide with air bearings considerably reduces particle emission over the work area. The gantry axis is equipped with recirculating ball bearing guides on both sides for robustness and precision in limited installation space.

This combination of different guide technologies means that the A-341 hybrid gantry is ideally suited to applications that are based on the step-and-scan principle and at the same time, require a compact design.

Absolute encoder

Absolute encoders supply explicit position information that enables immediate determination of the position. This means that referencing is not required during switch-on, which increases efficiency and safety during operation.

PIMag® magnetic direct drive

3-phase magnetic direct drives do not use mechanical components in the drivetrain, they transmit the drive force to the motion platform directly and without friction. The drives reach high velocities and accelerations. Ironless motors are particularly suitable for positioning tasks with the highest demands on precision because there is no undesirable interaction with the permanent magnets. This allows smooth running even at the lowest velocities and at the same time, there is no vibration at high velocities. Nonlinearity in control behavior is avoided and any position can be controlled easily. The drive force can be set freely.

Options and customized adaptations

  • Base made of granite or aluminum
  • Adjustable work height
  • Systems for reducing vibration
  • Additional drag chains
  • Performance of the linear motors
  • Liquid cooling of the linear motors

Application fields

Scanning, Digital printing, Electronics assembly and inspection, AOI (Automatic Optical Inspection), Automation.
