CNC Machinist Cover Letter Example

At Vantage Precision Components I set up and run a bank of Swiss-type lathes producing small stainless and titanium parts for surgical instruments, most lots between 500 and 5,000 pieces. I'm applying for the CNC Machinist opening at [Company name] because your shop runs the same kind of tight-tolerance, short-run medical work I've built my career around.

Programming is where I add the most value before a part ever hits the machine. I rebuilt our tool-offset library in Fanuc and cut average setup time from 70 to 42 minutes across our ten most common part families, and I proved out a new part number's first-piece inspection in under three hours instead of the shop's typical full shift.

I hold tolerances to +/-0.0002 inches on grinding-critical features, program directly at the control and in Mastercam Swiss, and inspect my own work with micrometers, bore gauges and a benchtop comparator before it reaches final QC. I've run lights-out unattended cycles on stable jobs for two years without a scrapped part.

I'd like to bring that setup-time and first-piece discipline to [Company name], and I'm glad to walk through a recent setup sheet or run a sample part in an interview. Thank you for your consideration.
