INSIDE MACHINE SHOP: SHOP 31

Shop 31 is a 536,400 square foot facility supporting all aspects of assembly, inspection, and machining, with secondary support for welding, non-destructive testing, and electroplating under one roof. Overhead clearance in our high bay area is over 80 feet. There are over 270 machine tools ranging from bench-top to the extra large "mammoth tools" to accommodate any size work. With over 90 cranes and a maximum lift capacity of 80 tons, combined with rail and waterfront access, virtually any product can be received, repaired/manufactured and shipped directly from our location.

Our turning capacity is 48 inch outside diameter by 80 feet long with a maximum weight of 80 tons. We can handle boring requirements up to 25 foot O.D. by 12 feet long. We can also do precision grinding work 10 inch O.D. by 28 feet long, I.D. grinding up to 60 inch by 56 inch high, flat grinding 12 feet long by 4 feet wide by 5 feet high, and can hone a cylinder 30 inch I.D. by 30 feet long. To complement the machining operations we have an Automated Storage and Retrieval Sawing System capable of tracking 500 different items up to 20 feet in length and 10 inches in diameter.

Shop 31 has an extensive array of CNC machinery with an average age of under 2 years. The Shop layout has recently been improved to expand our use of manufacturing cells: Prismatic, Mixed, Turn, Electrical Discharge Machines, Mid Size and Boring Cells are all fully equipped with many special features such as indexable lathe chucks, additional rotary axis, programmable facing heads, tool probing, live tooling, and tilting tables. We have introduced a new Factory Floor Integration System which provides all forms of digital data (ASCII, Raster, and Vector) directly on the shop floor for viewing. The DNC module automatically routes NC tape files to the machine tools required for the job. Our native CAD/CAM system, Intergraph, provides realistic checking of tool paths, placement of modular fixturing components, and extensive machine control capibilities directly from the 3-D models. We can work from digital or paper drawings, and maintain translators for DXF or IGES formats. We also offer inspection and reverse engineering services through the use of our Coordinate Measurement Machine (CMM) which is part of our DNC network, and can provide any level of documentation desired. The system is flexible enough for prototype or small lot orders and provides us the opportunity to discount repetitive and volume work.
