Set up and operate grinding, honing, lapping, or deburring machines to remove excess materials or burrs from internal and external surfaces.

Moves machine controls to index workpiece and adjust machine for pre-selected operational settings. Activates machine start-up switches to grind, lap, hone, debar, shear, or cut workpiece, according to specifications. Computes machine indexing and settings for specified dimension and base reference points. Studies blueprints, work order, or machining instructions to determine product dimensions, tooling, and to plan operational sequence. Observes and adjusts machine operation. Selects machine tooling to be used in machine operation, utilizing knowledge of machine and production requirements. Threads and hand feeds materials through machine cutters or abraders. Mounts and positions tools in machine chuck, spindle, or other tool holding device to specifications, using hand tools. Maintains stock of machine parts and machining tools. Repairs or replaces machine parts, using hand tools or notifies engineering personnel when corrective action is required. Brushes or sprays lubricating compound on workpiece or turns valve handle and directs flow of coolant against tool and workpiece. Lifts and positions workpiece manually or with hoist, and secures in hopper, on machine table, faceplate or chuck, using clamps. Inspects or measures workpiece, using measuring instruments, such as gauges or micrometers for conformance to specifications. Grinds, sharpens, or hones tools, dies, and products to prescribed dimensions, using power tools, hand tools, and precision measuring instruments. Measures workpieces and lays out work, using precision measuring devices.

Mechanical -- Knowledge of machines and tools, including their designs, uses, repair, and maintenance. Production and Processing -- Knowledge of raw materials, production processes, quality control, costs, and other techniques for maximizing the effective manufacture and distribution of goods.

Operation and Control -- Controlling operations of equipment or systems. Equipment Selection -- Determining the kind of tools and equipment needed to do a job. Operation Monitoring -- Watching gauges, dials, or other indicators to make sure a machine is working properly. Quality Control Analysis -- Conducting tests and inspections of products, services, or processes to evaluate quality or performance. Equipment Maintenance -- Performing routine maintenance on equipment and determining when and what kind of maintenance is needed.

Control Precision -- The ability to quickly and repeatedly adjust the controls of a machine or a vehicle to exact positions. Near Vision -- The ability to see details at close range (within a few feet of the observer). Manual Dexterity -- The ability to quickly move your hand, your hand together with your arm, or your two hands to grasp, manipulate, or assemble objects. Visualization -- The ability to imagine how something will look after it is moved around or when its parts are moved or rearranged. Finger Dexterity -- The ability to make precisely coordinated movements of the fingers of one or both hands to grasp, manipulate, or assemble very small objects. Information Ordering -- The ability to arrange things or actions in a certain order or pattern according to a specific rule or set of rules (e.g., patterns of numbers, letters, words, pictures, mathematical operations). Wrist-Finger Speed -- The ability to make fast, simple, repeated movements of the fingers, hands, and wrists.

Controlling Machines and Processes -- Using either control mechanisms or direct physical activity to operate machines or processes (not including computers or vehicles). Handling and Moving Objects -- Using hands and arms in handling, installing, positioning, and moving materials, and manipulating things. Getting Information -- Observing, receiving, and otherwise obtaining information from all relevant sources. Monitor Processes, Materials, or Surroundings -- Monitoring and reviewing information from materials, events, or the environment, to detect or assess problems. Repairing and Maintaining Mechanical Equipment -- Servicing, repairing, adjusting, and testing machines, devices, moving parts, and equipment that operate primarily on the basis of mechanical (not electronic) principles. Performing General Physical Activities -- Performing physical activities that require considerable use of your arms and legs and moving your whole body, such as climbing, lifting, balancing, walking, stooping, and handling of materials. Inspecting Equipment, Structures, or Material -- Inspecting equipment, structures, or materials to identify the cause of errors or other problems or defects. Identifying Objects, Actions, and Events -- Identifying information by categorizing, estimating, recognizing differences or similarities, and detecting changes in circumstances or events.
