Occupations | Sets up and operates grinding machines, such as surface and universal, carbide, drill, and tool-and-cutter grinders, to sharpen cutting tools to specifications, using blueprints, job orders, and knowledge of abrasives and metal properties: Reviews blueprints and job orders to plan production sequence. Selects grinding wheel of shape and grade and attaches to spindle, using wrenches. Positions and secures cutting tool on machine table, using magnetic chuck or holding fixture, or mounts tool on arbor and clamps between centers. Turns handwheels to position table or spindle to obtain specified taper and bevel on edges of cutting tools. Moves controls to set cutting tool rotation speed, feed rate, and grinding wheel rotation speed. Starts machine and turns wheel or engages feed to move workpiece to grinding wheel. Measures sharpened cutting tools to verify conformance to specifications, using fixed gauges, micrometers, calipers, optical comparators, and surface gauges. Dresses abrasive wheel to change cutting action or shape. May grind special $T3form tools,$T1 involving special setups and wheel dressing. May analyze specifications and select tooling to be used on production jobs. May design, modify, or make special tools according to specifications or tooling requirements. May braze or solder carbide tips to cutting tools. May be required to have specialized experience with particular type of cutting tool sharpened or machine operated and be designated Broach Grinder (machine shop); Drill Sharpener (machine shop); Hob Grinder (machine shop).

| Tends machines that crush, mix, or pulverize materials, such as limestone, shale, oyster shells, clay, iron ore, silica, gypsum, and cement clinkers, used in making cement: Starts mill and conveyors. Observes conveyor system to ensure continuous flow of material. Stops conveyor and removes clogged material, using bar. Opens chute over conveyor to add materials, such as iron, silica, or gypsum, according to specifications. Observes operation of auxiliary equipment, such as cement pumps, air or screen separators, air slides, cement coolers, and dust collectors. Turns valves to regulate water, air, and oil lines on machine, according to laboratory specifications. May regulate feeder mechanism on machines not equipped with automatic regulators. May add moisture to materials to facilitate flow into machine. May be designated according to type of mill tended as Ball-Mill Operator (cement); Finish-Mill Operator (cement); Hammer-Mill Operator (cement); Miller, Rod-Mill (cement); Pug-Mill Operator (cement); Raw-Finish-Mill Operator (cement); Tube-Mill Operator (cement); Vertical-Mill Operator (cement).

| Tends machine that pulverizes solid or semisolid materials used in manufacturing chemicals and related products: Installs screens of specified type and mesh in machine, using handtools, or starts auxiliary shakers (vibrating screens) that size ground particles. Starts feed conveyors, or shovels or dumps materials into machine hopper. Starts grinder and observes ground product discharged onto conveyors or into containers for impurities, lumps, or improperly sized particles. Cleans machine and conveyors, using airhose, scrapers, and brushes, to prepare equipment for grinding subsequent batches. May shovel ground product into containers for storage, shipment, or further processing. May tend machines that fill bags or drums with product. May weigh containers of materials, record weight, and enter number of containers filled on inventory records. May be designated according to material or product ground as Filtrose Crusher (chemical); Paradichlorobenzene-Machine Operator (chemical). (references) | |
| Operates bank of roll grinders to grind grain into meal or flour: Opens and closes slides in spouts to route grain to various grinders and sifters. Turns wheels to adjust pressure of grinding rollers for each break (passage of grain between rollers), according to grain size and hardness, and adjusts feed chutes to regulate flow of grain to rollers. Inspects product and sifts out chaff to determine percentage of yield. Adjusts rollers to maintain maximum yield. Replaces worn grinding rollers, using handtools. May sift and bolt meal or flour. May clean and temper grain prior to grinding. May direct workers who drain and temper grain and bolt meal or flour. May be designated according to grain milled as Corn Miller (grain-feed mills). May operate burr mills instead of roll grinders to grind grain and be designated Burr-Mill Operator (grain-feed mills). (references) | |
| Tends grinding mills that process baked or dried bulk cereal products prior to packaging: Starts grinder and opens chute gate on hopper to direct bulk cereal between grinding rolls. Sifts handful of ground and graded cereal through set of screens to determine whether cereal has been ground to specified size. Moves levers to adjust roll clearance in grinder to produce cereal comparable to that of screened sample. Cleans and replaces clogged or worn screens. (references) | |
| Tends machine that grinds cork into various shapes, such as semirounds, for shuttlecock bases and handle grips for fishing rods: Starts grinding machine and places workpiece in holding fixture or on arbor. Engages automatic feed or manually feeds cork against grinding drum of machine. May change grinding drums, using wrenches, to grind various shapes. (references) | |
