About this file

This Statement of Work (SOW) details requirements for a customized machine base for cannon manufacturing process equipment at Watervliet Arsenal. The machine base must accommodate multiple sub-systems including a Chuck Spindle Sub-System, Barrel Collar Clamp Sub-System, Barrel Muzzle Support, Process Application Sub-System, and measurement systems. Key specifications include a machine bed length of 18000-18250 mm, height of 525-750 mm, and width of 2000 mm, with precise linear motion guide rails and helical gear racks from specific manufacturers like SCHNEEBERGER.

The project requires the contractor to design, fabricate, deliver, and install the machine base within 38 weeks of contract award, with final acceptance to occur at Watervliet Arsenal. The contractor will be responsible for site preparation, rigging, installation, and providing a one-year onsite warranty covering labor, parts, and materials. Benet Laboratories will provide technical drawings, 3D models, and process application information after contract award. The machine is designed to handle workpieces with outer diameters between 80-350 mm and weights up to 2250 kg, with specific mounting and positioning requirements for cannon barrel manufacturing processes.
