Grace Okafor

CNC Machinist III

Wichita, KS · g.okafor@email.com · (555) 664-2758

Dear Hiring Manager,

I'm writing to apply for the CNC Machinist position at your company. I have six years of experience programming and operating Haas and Mazak 5-axis mills for aerospace-grade components, consistently holding tolerances within ±0.0005 inches.

At Prairie Precision Manufacturing, I programmed complex parts in Mastercam, set up and ran production jobs on titanium and aluminum stock, and reduced average cycle time on a key bracket assembly by 22% through optimized tool paths. I use CMM equipment for in-process inspection and maintain a scrap rate under 0.5% across roughly 3,000 parts machined per quarter.

I'm comfortable reading complex blueprints and GD&T callouts independently and have trained two junior machinists on setup procedures and lean 5S practices. I'd welcome the opportunity to bring that precision to your production floor and am open to second-shift scheduling if needed — I'm available for an interview at your convenience.

Sincerely,

Grace Okafor

How to Structure a CNC Machinist Cover Letter

Four short paragraphs is the sweet spot. Here is what each one should accomplish:

  1. 1Opening: state the role, machine proficiency, and a headline precision metric
  2. 2Body 1: detail programming and setup work with specific tolerances and volume
  3. 3Body 2: cover scrap-rate reduction, cycle-time gains, and quality inspection process
  4. 4Closing: tie to the employer's production needs and request an interview

Writing Tips for CNC Machinist Cover Letters

  • Lead with the machine controls and brands you're proficient on, like Haas or Mazak.
  • Quantify tolerance precision and scrap/rework rate.
  • Mention CAD/CAM software you use for programming, like Mastercam or SolidWorks.
  • Highlight cycle-time reductions or setup-time improvements you've delivered.
  • Note materials machined (aluminum, titanium, stainless) matching the posting.
  • Reference industries served, such as aerospace, medical, or automotive.
  • Close with willingness to work multiple shifts if the role requires it.
