Gantry positioning stage


H2W Technologies’ latest 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-B04), and each has a total stroke length of 25.67” [652mm]; can generate 6.2 lb [27.8N] of continuous force and 18.7 lb [83.3N] of peak force, or a combined 12.4 lb [55.6N] continuous force and 37.4 lb [166.6N] of peak force on the bottom axis.

The non-contact 1µm 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 extrusions, 90° right angle gussets, and custom extrusion end plates.

The system is mounted to a flat aluminum tooling plate base. There are also provisions that allow customer cables to be routed within the cable carriers. It has end-of-travel rubber bumper stops.

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