What are the responsibilities and job description for the Precision CNC Machinist — Close Tolerance Specialist position at Acme Machining?
Your day, crafted in thousandths
You start by studying the print—reading GD&T symbols, surface finish notes, material specifications, and the tolerance scheme—so you know exactly what the part demands. You load the required tools, establish tool and work offsets, and run a careful first-piece verification. With calipers, micrometers, bore and thread gauges, height gauges, and dial indicators in hand, you confirm every critical dimension before moving into production.
As the job runs, you keep the process tight—holding ±0.001 inch or better consistently. You watch for trends, make smart offset adjustments, and act the moment a dimension begins to drift, protecting quality and throughput alike.
What you do
- Hold close tolerances on a routine basis, achieving ±0.001 inch or tighter when required.
- Interpret complex blueprints, including GD&T, surface finish callouts, material specs, and overall tolerance stack-ups.
- Use precision instruments confidently: calipers, micrometers, bore gauges, thread gauges, height gauges, and dial indicators.
- Independently complete simple to moderate CNC setups: load tools, set offsets, and verify the first article.
- Monitor processes and adjust offsets to correct or prevent out-of-tolerance conditions.
