We are hiring a CNC Lathe Setup Machinist who can perform full setups, machine precision turned parts, and ensure all parts meet strict GD&T and dimensional requirements. 


Key Responsibilities:

  • Perform complete setups on CNC lathes (chucks, soft jaws, tool geometry, offsets).
  • Run first-article parts and verify dimensional accuracy before production.
  • Read and interpret engineering drawings and GD&T feature control frames.
  • Operate CNC lathes and maintain quality throughout the run.
  • Inspect parts using micrometers, bore gauges, indicators, calipers, etc.
  • Make minor program edits and adjust offsets when needed.
  • Select appropriate inserts, tooling, speeds and feeds.

Skills:

  • Ability to perform independent CNC lathe setups from start to finish.
  • Strong ability to read prints and GD&T for features of the part.
  • Proficiency with precision inspection tools (bore gauges, micrometers, indicators).
  • Understanding of tool nose compensation, insert selection, and turning strategies.
  • Experience with chucking, soft jaws, collets, and concentricity control.
  • Ability to hold tight tolerances (+/- .0005 or tighter depending on print).
  • Familiarity with G/M codes, canned cycles, and program adjustments.
  • Knowledge of cutting principles: SFM, feed per rev, chip control, and heat.
  • Strong troubleshooting skills for dimensional and finish issues.
  • Able to work independently with minimal supervision. 

Qualifications:  

  • 3-5 years CNC lathe set up experience required.
  • Machining certificate or vocational training a plus.
