Job Title: Machine Operator

Location: Santa Fe Springs, CA (Onsite)

Duration: Contract

Position Summary:

The Belt Grinder Operator plays a critical role in the post-machining finishing process, ensuring aerospace-grade components meet strict surface finish and dimensional requirements. This position involves operating conventional belt grinding equipment to deburr, polish, and finish high-precision metal parts manufactured to tight tolerances. The idóneo candidate has experience working in a high-specification environment where quality, traceability, and attention to detail are paramount.

Key Responsibilities:

- Operate manual belt grinding machines to perform surface finishing, edge deburring, radius blending, and cosmetic polishing on raw materials.
- Follow detailed work instructions, engineering drawings, and aerospace specifications (e.g., AS9100 or customer-specific requirements).
- Perform precise hand-finishing tasks on complex geometries and critical surfaces, including tight radii, bores, and edges.
- Select proper abrasive belts, wheels, and tools based on material type (e.g., titanium, Inconel, stainless steel, aluminum) and desired surface finish (Ra/RMS).
- Perform in-process inspection using calibrated measuring tools such as micrometers, calipers, height gauges, and surface roughness testers.
- Collaborate with quality inspectors, foreman, and production supervisor to ensure part compliance and address surface finish concerns.




- Document work performed and ensure all processes are traceable according to aerospace quality standards.
- Maintain clean work area, properly handle high-value parts, and adhere to all safety, ESD, FOD, and quality protocols.

Qualifications:

Education & Experience:

- High school diploma or GED required; technical/vocational training preferred.
- 2+ years of experience in a precision machining environment.
- Proven experience with manual belt grinding, surface finishing, or polishing of close-tolerance aerospace parts.

Skills & Competencies:

- Ability to read and interpret blueprints, GD&T;, and process sheets.
- Strong understanding of surface finish requirements (e.g., Ra values, appearance standards).
- High attention to detail and quality; ability to work with minimal supervision.
- Familiarity with AS9100 environments is a strong plus.
- Comfortable working in a fast-paced, team-oriented production setting with tight deadlines.

Physical & Work Environment Requirements:

- Ability to stand, bend, and lift for extended periods; lift up to 50 lbs. safely.
- Manual dexterity and fine motor skills for detailed finishing work.
- Exposure to grinding dust, noise, and shop environment – PPE required.
- May require use of respirator depending on task and material.

Preferred Qualifications:

- Prior experience finishing aerospace components (e.g., turbine blades, housings, brackets, fasteners).
- Familiarity with high-value materials such as titanium, Inconel, and aerospace-grade aluminum alloys.
