TOBYHANNA ARMY DEPOT, Pa. - Back shell nut wrenches are used to tighten back shell nuts on large cable assemblies here. The wrenches are cut from sheets of steel by a water jet cutting machine, used by employees in the Machining Branch to cut various types of material, such as steel, aluminum, plastic, copper, brass, glass and rubber. The machine is capable of making hundreds of wrenches per day, depending on its size.

The 36 employees in the branch, which is part of the Systems Integration and Support Directorate, work on Computer Numerical Control and manual machines. CNC machines include mills, which are used to shape metal; lathes, which spin material to allow for symmetrical cutting and sanding and the water jet. Manual machines include lathes, saws, drill presses, surface grinders and rubber molding.

Branch personnel may purchase a smaller water jet cutting machine because there is a large demand for the parts that are cut out using the machine, noted John Roskowski, branch work leader.
