Swiss CNC Operator

Mace Machine LLC – Exeter, New Hampshire

Mace Machine is seeking an experienced Swiss CNC Operator to operate Citizen Swiss-style CNC machines and produce high-quality precision components. This position does not require programming experience; however, the ability to make minor program edits is a plus.

We are a growing precision machine shop specializing in small-diameter components for the aerospace, defense, RF/microwave, electronics, and other demanding industries. Our work is varied and technically challenging, with a strong emphasis on quality, teamwork, and continuous improvement.

Follow established programs, setup sheets, work instructions, and job travelers
Perform routine tool changes and replace worn or damaged inserts
Make tool offsets and dimensional adjustments based on inspection results
Monitor parts for dimensional accuracy, surface finish, and visual defects
Perform first-piece and in-process inspections using precision measuring equipment

Assist with machine setups and changeovers based on experience
Maintain a clean, organized, and safe work area
Support efforts to improve quality, productivity, and process consistency
Follow all quality, safety, FOD, and material-handling requirements

What We’re Looking For

Previous experience operating Swiss-style CNC machines or similar CNC equipment
Experience with Citizen machines and FANUC or Mitsubishi controls is preferred
Ability to read and interpret blueprints, dimensions, tolerances, and basic GD&T
Ability to use micrometers, calipers, indicators, gage pins, optical inspection equipment, and other precision measuring instruments

Ability to recognize tool wear, dimensional changes, and production problems
Strong attention to detail and commitment to quality
Ability to follow established processes and maintain accurate records
Dependability and the ability to work effectively as part of a team

Experience making minor CNC program edits is a plus but is not required. Experience in aerospace, defense, or an AS9100 manufacturing environment is also beneficial but not required.
