High Precision Single Rail Positioning Stage H-Gantry

The high precision single rail positioning stage H-gantry design is an open frame XY positioning system. It has two bottom parallel axes with one cross axis connecting the two (H-gantry).

Each linear axis uses H2W’s brushless linear motors (BLDM-C04), and each has a total stroke length of 25.0 in [635 mm]; can generate 13.0 lbs [58 N] of continuous force and 39.0 lbs [173 N] of peak force, or a combined 26.0 lbs [116 N] continuous force and 78.0 lbs [346 N] of peak force on the bottom axis. The non-contact 1-micron resolution encoders allow for precise positioning. The moving tables are guided by a precision recirculating linear ball bearing system. The linear axes are assembled on a single piece of aluminum extrusion, thus reducing the overall weight of the system. The top cross axis is mounted to the bottom parallel axis using rigid aluminum plates. The system is mounted to a flat aluminum tooling plate base. It has end-of-travel rubber bumper stops and a home sensor (reference mark). There are also provisions that allow customer cables to be routed within the cable carriers.

Additional options include, end-of-travel-sensors, and custom mounting holes. Single extrusion length of up to 6 m long, allows for longer stroke applications.
