Occupations | Sets up and operates external grinding machines to grind external cylindrical and tapered surfaces of rotating metal workpieces, such as tool, die, and machine parts, usually for limited runs, analyzing blueprints and specifications and selecting tooling according to knowledge of external grinding procedures: Studies blueprint or layout on workpiece to visualize grinding to be done and plans sequence of operations. Selects grinding wheel, according to knowledge of metal properties and abrasives, and mounts wheel on spindle. Dresses wheel manually or with preset dressing device. Moves controls and reads dials to set angle of workpiece to grinding wheel. Positions and secures workpiece between centers, on magnetic chuck, or in chuck jaws, using wrenches. Selects and sets grinding wheel speed, work surface speed, and travel rate of powered table. Positions and tightens stops to set depth of grinding wheel cut and stroke of worktable. Moves controls to feed wheel to workpiece manually or automatically. Turns valve handle and directs flow of coolant against wheel and workpiece. Verifies dimensions of ground workpiece for conformance to specifications, using such measuring instruments as micrometers, dial indicators, and gauge blocks. May dress grinding wheel to specified profile for contour grinding, using special fixtures and tools. May grind nonmetallic materials. May operate tracer attachment to duplicate contours from templates or models. May be required to have experience with particular material, product, or precision level, or with machine of particular size, type, or trade name. May set up machines for other workers. May be designated according to type of machine operated as Roll Grinder Operator (machine shop). (references) |

Positions and secures workpiece on faceplate, magnetic chuck, or in chuck jaws, using wrenches. Selects and sets grinding wheel speed, work surface speed, and workpiece table travel rate, according to knowledge of metal properties and abrasives. Positions and tightens stops to set depth of grinding wheel cut and stroke of workpiece table. Moves controls to feed wheel to workpiece manually and automatically. Turns valve handle and directs flow of coolant against wheel and workpiece. Verifies dimensions of ground workpiece for conformance to specifications, using such measuring instruments as micrometers, dial indicators, and gauge blocks. May dress grinding wheel to specified profile for contour grinding, using special fixtures and tools. May grind nonmetallic materials, such as plastics. May operate tracer attachment to duplicate contours from templates or models. May be required to have experience with particular material, product, or precision level, or with machine of particular type or trade name. (references) | |
| Sets up and operates surface grinding machines with horizontal or vertical spindle and reciprocating or rotating table to grind flat or contoured surfaces of metal workpieces, such as tool, die, and machine parts, usually for limited runs, analyzing specifications and selecting tooling according to knowledge of surface grinding procedures: Studies blueprint or layout on workpiece to visualize grinding to be done and plans sequence of operations. Positions and secures workpiece on magnetic chuck, in holding fixture, or directly to machine table. Selects grinding wheel, grinding speeds, and feed rates for each operation according to knowledge of metal properties and abrasives, and mounts wheel on spindle. Moves device to dress wheel. Moves controls and reads dials to set rotation speeds and feed rates. Positions and tightens stops to limit table travel. Moves controls to feed workpiece to wheel or vice versa. Turns valve handle and directs flow of coolant against wheel and workpiece. Verifies dimensions of ground workpiece for conformance to specifications, using such measuring instruments as micrometers, comparators, dial indicators, gauge blocks, and load test equipment. May dress grinding wheel to specified profile for contour grinding, using special fixtures and tools. May grind nonmetallic materials, such as plastics. May operate tracer attachment to duplicate contours from templates or models. May be required to have experience with particular material, product, or precision level, or with machine of particular size, type, or trade name. (references) | |
| Tends machine that grinds approximate curves on lens blanks preparatory to fine grinding: Selects lens blanks as specified on production order. Places lens blank in holder and positions holder and lens assembly on diamond $T3lap I$T1 of grinding machine. Lowers spindle of weighted arm onto lens holder to hold lens on lap. Starts machine and moves control arm back and forth to grind lens blanks to specified curvature or holds lens blank against grinding wheel to grind blank. Removes blank from holder and washes blank in water to remove grinding abrasive. Measures blanks to verify specified curvature, using lens gauge. (references) | |
