Environment

Food Manufacturing

The Maintenance Machinist is responsible for manufacturing, repairing, modifying, and rebuilding precision mechanical components used on food-processing, packaging, conveying, and facility equipment. This position operates manual machine tools and works closely with Maintenance, Engineering, and Operations to minimize equipment downtime and improve equipment reliability.

A key responsibility is the ability to reverse-engineer damaged, worn, or obsolete components when replacement parts or drawings are not readily available. All work must be performed in accordance with plant safety, food safety, sanitation, and quality requirements.

• Operate manual lathes, milling machines, drill presses, saws, grinders, and other machine-shop equipment.
• Manufacture replacement components such as shafts, bushings, sleeves, spacers, pins, rollers, brackets, guides, and equipment hardware.
• Repair and modify damaged or worn production equipment components.
• Reverse-engineer existing or damaged parts using measurements, sketches, drawings, and equipment requirements.
• Perform turning, facing, boring, drilling, milling, tapping, threading, reaming, keyway cutting, grooving, and related machining operations.
• Machine internal and external threads and repair damaged threaded components.
• Perform precision measurements using micrometers, calipers, dial indicators, bore gauges, thread gauges, and other measuring instruments.
• Maintain required dimensional tolerances, fits, clearances, and surface finishes.
• Machine and repair shafts for bearings, sprockets, pulleys, couplings, seals, and other rotating components.
• Support repairs involving conveyors, rollers, bearings, gearboxes, motors, pumps, packaging equipment, and food-processing machinery.
• Assist Maintenance technicians during equipment breakdowns when machining or component modification is required.
• Manufacture temporary or permanent repair components when OEM replacement parts are unavailable or have extended lead times.
• Work with Maintenance and Engineering to improve component reliability and eliminate recurring equipment failures.
• Recommend improvements to component materials, dimensions, fits, or designs when appropriate.
• Read and interpret mechanical drawings, blueprints, equipment manuals, sketches, and specifications.
• Create basic sketches and record dimensions for fabricated or reverse-engineered components.
• Select appropriate cutting tools, speeds, feeds, materials, and machining methods.
• Maintain machine-shop equipment, cutting tools, fixtures, tooling, and precision measuring instruments.
• Maintain an organized inventory of commonly used raw materials and machine-shop supplies.
• Complete work orders and document fabricated components, repairs, measurements, and modifications.
• Maintain a clean, organized, and safe machine-shop environment.

• Follow all plant GMP, food safety, sanitation, and quality procedures.
• Use materials appropriate for food-processing applications when required.
• Understand the importance of sanitary equipment design and avoiding potential product-contamination points.
• Prevent metal shavings, cutting fluids, lubricants, tools, and foreign materials from entering production areas or food-contact zones.
• Properly clean fabricated components before they are released for installation on production equipment.
• Maintain separation and control of materials used for food-contact and non-food-contact applications.
• Support production equipment repairs while maintaining plant food-safety requirements.
• Coordinate with Maintenance and Operations before returning repaired equipment to production.

• High school diploma or GED required.
• Technical school, machinist apprenticeship, or machining certification preferred.
• 3+ years of manual machining experience preferred.
• Industrial maintenance or manufacturing experience strongly preferred.
• Food-manufacturing experience preferred.
• Strong experience operating manual lathes and milling machines.
• Strong understanding of machining tolerances, fits, clearances, speeds, feeds, and tooling.
• Ability to read mechanical drawings and blueprints.
• Strong precision-measurement skills.
• Ability to reverse-engineer components from samples or damaged parts.
• Experience machining stainless steel strongly preferred.
• Ability to work with stainless steel, carbon steel, aluminum, plastics, and other industrial materials.
• Understanding of bearings, shafts, seals, sprockets, pulleys, couplings, and other mechanical components.
• Welding and fabrication experience is a plus.
• Basic CAD or mechanical drawing experience is a plus.

• Manual lathe operation
• Manual milling
• Precision measurement
• Stainless-steel machining
• Blueprint and mechanical drawing interpretation
• Reverse engineering
• Shaft and bearing fits
• Internal and external threading
• Keyways and shaft repair
• Drilling, boring, tapping, and reaming
• Tolerance and clearance calculations
• Mechanical troubleshooting
• Material identification
• Cutting-tool selection and setup
• Equipment repair and modification
• Food-manufacturing GMP and sanitation practices

• Follow all Lockout/Tagout (LOTO) procedures.
• Follow machine guarding and machine-shop safety requirements.
• Wear required PPE.
• Inspect machine tools and tooling before operation.
• Safely secure workpieces before machining.
• Use appropriate lifting equipment for heavy components.
• Immediately report unsafe conditions, damaged tooling, or machine deficiencies.
• Never bypass safety devices or machine guarding.
• Follow all plant safety and food-safety policies.

• Ability to stand and operate machine tools for extended periods.
• Ability to lift and safely handle machine components and raw materials.
• Ability to bend, reach, climb, kneel, and work around industrial equipment.
• Ability to safely use hoists and other lifting devices.
• Ability to work in production environments that may include heat, cold, moisture, noise, and operating machinery.
• Ability to respond to equipment breakdowns throughout the manufacturing facility.

• Quality and accuracy of machined components.
• Equipment repair turnaround time.
• Response to production breakdowns.
• Reduction of equipment downtime.
• Quality of reverse-engineered components.
• Ability to manufacture obsolete or difficult-to-source replacement parts.
• Proper documentation of completed work.
• Machine-shop organization and tooling control.
• Safety and food-safety performance.
