Job description
Work involves studying blueprints or layouts to plan a grinding sequence, selecting and mounting the right grinding wheel for the material and tolerance required, and then smoothing, sharpening, or polishing metal workpieces by hand or machine while checking dimensions against specifications throughout. Because the pace is fast and deadline-driven, grinders often work as part of a larger machine shop or production line, feeding finished pieces on to assembly or inspection stations.
Pros
- Pay can reach over $77k for skilled precision grinding work
- Entry with just a high school diploma and on-the-job training
- Hands-on, tactile craft using specialized abrasives and grinding equipment
Cons
- Employment is projected to shrink over the next decade (-7.8%)
- A relatively small, geographically limited occupation nationwide
- Fast-paced, deadline-driven work where precision and accuracy are essential
A typical day
The morning queue at the grinding bench is a shop's dull edge inventory: end mills with worn corners, drills that wander, a box of router bits from the cabinet shop down the road. Each tool gets assessed first -- some need a touch-up, some a full regrind, and a few are honest scrap. The skill is in the angles: matching original clearances and reliefs by eye and fixture, checking with a comparator, because a wrongly ground drill cuts worse than a dull one. The afternoon adds a surface-grinding job on flat stock, and the day ends dressing wheels for tomorrow.
Tasks at the job
- Inspect, feel, and measure workpieces to ensure that surfaces and dimensions meet specifications.
- Select and mount grinding wheels on machines, according to specifications, using hand tools and applying knowledge of abrasives and grinding procedures.
- File or finish surfaces of workpieces, using prescribed hand tools.
- Perform basic maintenance, such as cleaning and lubricating machine parts.
- Monitor machine operations to determine whether adjustments are necessary, stopping machines when problems occur.
- Study blueprints or layouts of metal workpieces to determine grinding procedures, and to plan machine setups and operational sequences.
Workplace & working conditions
Work happens indoors, though not always in a climate-controlled space, and most of the day is spent on your feet. Noise levels can be distracting or uncomfortable. The role involves regular exposure to hazardous equipment or conditions and contaminants, and standard protective equipment (gloves, safety glasses, and similar) is expected.
The pace is often fast, with real time pressure to meet deadlines. Precision and accuracy are essential to the work.
Education necessary or common
High school diploma; some on-the-job training or apprenticeship
Licenses & certifications
- OSHA 10
- NIMS credentials (helpful)
