Rolling Machine Setters, Operators, and Tenders, Metal and Plastic — Tasks

Task statements

• Activate shears and grinders to trim workpieces.
• Monitor machine cycles and mill operation to detect jamming and to ensure that products conform to specifications.
• Adjust and correct machine set-ups to reduce thicknesses, reshape products, and eliminate product defects.
• Start operation of rolling and milling machines to flatten, temper, form, and reduce sheet metal sections and to produce steel strips.
• Examine, inspect, and measure raw materials and finished products to verify conformance to specifications.
• Read rolling orders, blueprints, and mill schedules to determine setup specifications, work sequences, product dimensions, and installation procedures.
• Manipulate controls and observe dial indicators to monitor, adjust, and regulate speeds of machine mechanisms.
• Set distance points between rolls, guides, meters, and stops, according to specifications.
• Calculate draft space and roll speed for each mill stand to plan rolling sequences and specified dimensions and tempers.
• Install equipment such as guides, guards, gears, cooling equipment, and rolls, using hand tools.
• Position, align, and secure arbors, spindles, coils, mandrels, dies, and slitting knives.
• Fill oil cups, adjust valves, and observe gauges to control flow of metal coolants and lubricants onto workpieces.
• Signal and assist other workers to remove and position equipment, fill hoppers, and feed materials into machines.
• Record mill production on schedule sheets.
• Direct and train other workers to change rolls, operate mill equipment, remove coils and cobbles, and band and load material.
• Thread or feed sheets or rods through rolling mechanisms, or start and control mechanisms that automatically feed steel into rollers.
• Select rolls, dies, roll stands, and chucks from data charts to form specified contours and to fabricate products.
• Remove scratches and polish roll surfaces, using polishing stones and electric buffers.
• Disassemble sizing mills removed from rolling lines, and sort and store parts.
