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-351 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.
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.
