MACHINIST (Title 32)
This position is located in the Joint Forces Headquarters-State, Logistics Directorate (J-4), Surface Maintenance Facility. The primary purpose of this position is to manufacture parts and items of equipment from raw stock of different metals and metal alloys in support of maintenance activities. Performs machining work to manufacture castings, forgings, weldments, and other fabrications. Plans and lays out work from blueprints, sketches, drawings, part models, and other specifications and instructions. Receives work orders that indicate what work is to be done and plans work accordingly. Uses trade mathematics and standard handbook formulas in making computations to establish dimensions not provided in verbal instructions or written specifications. Determines work procedures, machines, tools, equipment, and attachments to be used; from a variety of metals, metal alloys, and other materials. Sets up and operates most types of conventional and/or Computer Numerical Control (CNC) machine tools such as lathes; vertical and horizontal boring mills; bench, plane, or universal milling machines; shapers and planers; internal and external grinders, thread grinders; and radial drills. Grinds and sharpens tools, and selects tools, jigs, and fixtures required to achieve specific dimensions, tolerances, and surface finishes. Sets up work in vises and between centers, uses chucks, standard faceplates, angle plate mountings, and collets. Performs precision handwork to finish, fit, and assemble machined parts. Uses various bench-mounted and handheld powered and non-powered tools such as files, drills, reamers, and buffers. Performs heat-treating, welding, and soldering. Military Grades:
