ATS3600 Mechanical Bearing, Screw-Driven Linear Stage with Aperture


Design Features

  • Large, clear aperture
  • Travel range from 100 mm x 100 mm to 400 mm x 400 mm
  • High-performance linear motion guides
  • 15 arc sec orthogonality
  • Noncontact linear encoder for high accuracy

The demand for a high accuracy, robust, open-frame stage is met with the ATS3600. This dual-axis, large aperture, open-frame stage addresses the unique needs of scanning microscopy, wafer and printed circuit board inspection and automated assembly.

Design and Construction

Unlike other designs that are assembled from several discrete pieces, the ATS3600 is a three-piece design. This allows critical components such as orthogonality, straightness and flatness to be controlled during the initial machining, resulting in a stage with exceptional geometrical tolerances and inherent orthogonality.

The ATS3600 utilizes high-precision linear motion guide (LMG) bearings, with a total of four trucks per axis. These make the ATS3600 ideal for fast, repetitive operations. The LMG bearings also exhibit exceptional stiffness, high load capacity and extremely low friction.

The high stiffness inherent in this stage allows it to be side-driven, yet still retain excellent performance characteristics. The ATS3600 represents a major upgrade in performance over typical side-drive stages.

Motors and Drives

The ATS3600 includes two high-performance NEMA 23 BMS series brushless, slotless motors, and a SM60 stepper motor. This motor has all of the advantages of a brushless motor – high acceleration, no brushes to wear and lower heating – yet has zero cogging for the ultimate in smooth motion.

Optional Linear Encoder Feedback

A high-resolution, noncontact linear encoder is available as an option. This noncontact encoder offers exceptional repeatability and stability over a range of operating conditions. Both digital and analog output versions are available. The digital version has a resolution of 0.1µm, while the analog version, can be coupled to achieve µm-level resolutions.

Alternate Configurations

All stage travels offer both single- and dual-axis designs, as well as the option for a solid tabletop.

Integration (Required)

Aerotech offers both standard and custom integration services to help you get your system fully operational as quickly as possible. The following standard integration options are available for this system. Please consult Aerotech if you are unsure what level of integration is required, or if you desire custom integration support with your system.
-TAS Integration - Test as system
Testing, integration, and documentation of a group of components as a complete system that will be used together (ex: drive, controller, and stage). This includes parameter file generation, system tuning, and documentation of the system configuration.
-TAC Integration - Test as components
Testing and integration of individual items as discrete components. This is typically used for spare parts, replacement parts, or items that will not be used or shipped together (ex: stage only). These components may or may not be part of a larger system
