Machine Monitoring: Observe machine operations during production runs to detect potential malfunctions, unusual vibrations, or tool wear; report issues immediately to supervisors or lead machinists.
Part Finishing: Perform secondary operations such as deburring, cleaning, and stamping finished metal or plastic parts.
Documentation: Accurately record production counts, part inspection results, and downtime logs in the shop floor management system.
Shop Maintenance: Maintain a clean, organized work area adhering to strict 5S and OSHA safety standards, including proper chip removal and coolant management.
Required Qualifications & Experience
CNC Operating Experience: Minimum of 1 to 2 years of hands-on experience operating CNC lathes and/or CNC milling machines in a manufacturing or machine shop environment.
Blueprint Reading: Ability to read and interpret basic mechanical engineering drawings, tolerances, and process sheets.

Physical Stamina: Ability to stand for extended periods, bend, reach, and lift up to 50 lbs regularly.
Preferred Qualifications
