Own the Setup. Shape Precision.
From first-piece signoff to steady-state production, you will be the point person setting up and running through-feed centerless grinding equipment to produce precision bearing rings, rollers, and pins. You’ll support both the side lap and centerless areas, ensuring every component meets exacting dimensional and surface criteria.
A day in the role
- Prep the machine: establish work blade height, set regulating wheel angle and speed, and align guides/fences for through-feed stability.
- Tooling and wheels: mount, balance, and dress grinding and regulating wheels; replace worn tooling and fine-tune as necessary.
- Manual feed discipline: hand-feed a continuous stream of parts at a consistent rate, keeping pieces touching with no gaps and never exceeding the machine’s set through-feed speed.
- Gauging and verification: use micrometers, verniers, microscope, OD dial gauges, optical comparator, and fixed/variable gauges; verify calibration before use.
- Run and improve: follow certified processes/engineered cycles and setup cards; document parameters for repeatable changeovers and efficient future runs.
- Troubleshoot like a pro: identify and correct chatter, burn/discoloration, lobing, taper, barrel/hourglass shape, feed marks, and size drift.
- Coach and collaborate: train operators on machine operation, gauging, and wheel changes; partner with team leads to resolve issues quickly.
- Safety and 5S: maintain a clean, organized work area; follow all safety rules and OSHA requirements.
- Material handling: move parts, materials, and containers as needed to complete work.
Core skills and abilities
- Read and interpret procedures, setup cards, drawings, and verbal instructions; follow standard processes without deviation.
- Shop math proficiency; comfort with both inch and metric systems.
- Working knowledge of GD&T related to roundness and surface roughness (RA).
- Proven ability to independently set up and hold ±0.0001" (2.5 µm) or tighter on size and roundness.
- Maintain production throughput while meeting stringent quality standards; record results for audit readiness.
- Spot and report irregularities in fits, finishes, part quality, or technique; communicate clearly and train others.
Education and experience
- High school diploma or GED.
- 3+ years of hands-on centerless setup experience with required through-feed grinding.
- Demonstrated skill in consistent, continuous hand-feeding at a constant through-feed rate without separation or over-pushing.
- Track record diagnosing and correcting geometry, surface, and operational/manual-feeding issues (out-of-round, taper, barrel/hourglass, size variation/drift, chatter, burn).
Preferred qualifications
- Experience setting up Nissin centerless grinders.
- Background in grinding precision bearing components (rings, rollers, pins).
- Technical or vocational certificate in machining or grinding.
- Expertise setting center height, blade top angle, and regulating wheel inclination to prevent lobing and control through-feed rate.
- Use of structured centerless troubleshooting methods/references.
Physical demands
- Standing, walking, bending, reaching, grabbing, twisting, carrying, pushing, and pulling.
- Ability to lift up to 40 lbs.
Tools and environment
- Equipment: Centerless Grinder; OD/ID Grinding Machine.
- Context: aerospace manufacturing; machine setups for production runs; high-precision manufacturing environment.
