Overview

The MGS gantry system has been designed to maximize throughput for applications requiring overhead motion. This stage is ideal for 3D printing, assembly, pick-and-place, alignment, inspection, and industrial automation applications.

The MGS uses preloaded linear mechanical bearings which are designed to provide optimized stiffness and precision. Optional stainless steel guide rails can be delivered.

The gantry axis incorporates dual linear motors and dual linear encoders. Ironless linear motors provide smooth motion and no cogging or attractive forces. The linear motor and linear encoders are noncontact devices, so there is no backlash, wear, or maintenance concerns.

The A-352 is coupled with industry-leading controllers and drive modules from ACS that offer superior servo performance, advanced control algorithms to improve dynamic performance and error compensation, and a wide suite of software development tools.

Application fields

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

Options and customized adaptations

Base made of granite
Customizable work height
Support stands with and without vibration isolation
Additional drag chains
Increased performance motors
Liquid cooling of the linear motors
