CNC Maintenance Mechanic

Position Purpose

The CNC Maintenance Mechanic keeps our 14 CNC lathes and mills and 1 saw running accurately and safely. This person owns the preventive maintenance (PM) program and performs mechanical, electrical, hydraulic and pneumatic repairs to minimize unplanned downtime.

As the shop's primary maintenance resource, the mechanic works closely with machinists, programmers and production leadership to schedule PMs around production and get machines back in service quickly when they go down.

Essential Duties and Responsibilities

Preventive maintenance

• Plan, schedule and perform daily, weekly, monthly and annual PMs on all CNC lathes and mills per manufacturer recommendations.
• Inspect, clean and lubricate ways, ballscrews, spindles, turrets, tool changers and chip conveyors; change way oil, hydraulic oil, spindle oil and filters.
• Maintain coolant systems: check concentration, clean sumps, replace filters and pumps.
• Check and adjust gibs, backlash, belt tension, hydraulic chuck pressure and air pressure.
• Perform machine leveling, alignment and geometry checks (ballbar, test indicator, spindle runout) and adjust compensation as needed.
• Inspect and maintain support equipment: air compressors, dryers, mist collectors, saws and material handling.

Repairs and troubleshooting

• Respond quickly to machine breakdowns and alarms; diagnose root cause and restore machines to service.
• Troubleshoot and repair mechanical systems: spindles, bearings, ballscrews, way covers, turrets, ATCs, tailstocks, bar feeders and chip conveyors.
• Troubleshoot electrical and control issues: 120/240/480V power, servo and spindle drives, motors, encoders, sensors, limit switches and relays, using schematics and a multimeter.
• Diagnose hydraulic and pneumatic faults: pumps, valves, cylinders, regulators and leaks.
• Read and use CNC control diagnostics (e.g., Fanuc, Haas, Mazak, Okuma), parameters, ladder/PLC displays and alarm histories.
• Coordinate with OEM service techs and outside vendors on warranty work or complex repairs.

Records, parts and continuous improvement

• Document all PMs, repairs, downtime and parts used in the maintenance log or CMMS.
• Track recurring failures and recommend fixes to improve machine reliability and uptime.
• Maintain a critical spare parts inventory; source and order parts within budget.
• Keep the maintenance area, tools and manuals organized.

Safety

• Follow all safety rules, including lockout/tagout (LOTO), PPE and safe handling of oils and coolants.
• Verify machine guards, interlocks, door switches and e-stops are working after every repair.
• Report unsafe conditions and take part in safety training.

Other

• Perform minor facility maintenance as needed.
• Train machine operators on daily checks and basic care.
• Other duties as assigned.

Qualifications

Required

• High school diploma or GED.
• 5 years of hands-on maintenance experience on CNC machine tools (lathes and/or machining centers) in a manufacturing setting.
• Working knowledge of mechanical, electrical (including 480V three-phase), hydraulic and pneumatic systems.
• Ability to read electrical schematics, hydraulic/pneumatic diagrams, mechanical drawings and OEM manuals.
• Skilled with multimeters, dial and test indicators, micrometers and standard mechanic's hand and power tools.
• Strong troubleshooting skills and the ability to work independently with minimal supervision.
• Basic computer skills for logging work and looking up parts and manuals.
• Must provide own basic hand tools.
• Valid driver's license (for occasional parts runs).

• Experience with Fanuc, Haas, Mazak, Okuma or Doosan controls and parameters.
• Experience with spindle rebuilds, ballscrew replacement and machine alignment (ballbar testing).
• PLC / ladder logic troubleshooting.
• Basic welding and fabrication skills.
• Forklift certification.
• Experience setting up or running a CMMS-based PM program.

Physical Demands and Work Environment

• Stand, walk, bend, kneel, crawl and climb ladders for extended periods; work in tight spaces inside and behind machines.
• Lift and carry up to 50 lbs regularly; heavier components moved with hoists, forklifts or a second person.
• Good manual dexterity and near vision for detailed mechanical and electrical work.
• Shop environment with noise, metal chips, cutting oils and coolants; seasonal heat and cold.
• Exposure to moving machinery and high-voltage electrical systems; required PPE includes safety glasses, hearing protection and safety-toe boots.

Reasonable accommodations may be made to enable individuals with disabilities to perform the essential functions.
