Role Summary
Operate and setting CNC milling machines (primarily 5-axis) and support manual machining (mills/lathes) for tooling manufacture/refurbishment, manufacturing parts and tooling to tight tolerances with full paperwork and traceability in an aerospace-quality environment.
Key Responsibilities
- Set and run CNC 5-axis milling machines to produce patterns, CNC machining fixtures and composite parts to drawing/specification.
- Support manual machining tasks (manual mill, Colchester lathe, pillar drills) for tooling manufacture/refurbishment.
- Read and interpret engineering drawings and specifications (including GD&T where applicable).
- Select tools, set offsets, set datums, prove out jobs, and optimise feeds/speeds within agreed process limits.
- Carry out first-off and in-process inspection using precision measuring equipment; record results accurately.
- Maintain paperwork, job packs, and traceability documentation to aerospace standards.
- Escalate quality concerns, raise/assist with NCRs where required, and support continuous improvement.
- Maintain safe working practices, housekeeping and correct PPE usage.
Required Qualifications & Skills (Must-have)
- Strong CNC milling experience operating and setting 3 to 5-axis machines.
- Manual machining capability (manual mill and lathe) for tooling work.
- Conversant with CNC controls (Fanuc and Heidenhain knowledge particularly useful; other controls considered).
- Strong understanding of paperwork/traceability requirements in a controlled/regulated environment.
- Confident interpreting technical drawings and working to tight tolerances.
- Quality-focused, reliable, and able to work to output targets under a Section Head’s direction.
Preferred Qualifications & Skills (Nice-to-have)
- Experience in aerospace, composites, defence, or similarly regulated industries.
- 5-axis experience (beneficial but not essential if the right 3-axis/hand skills and attitude to learn are present).
Machines / Plant & Capability (site-specific)
- 5-Axis machining centres (4 total):
- Belotti Vaga x 2
- Belotti FLA Twin Pallet x 1
- MultiAX x 1
- Controls: Fanuc or Heidenhain.
- Composite machining capability: parts from approx. 200mm cubed up to 6m x 3m x 3m.
- Metallic cutting / tooling manufacture & refurb equipment:
- Haas CNC mills (3 + 1)
- Colchester lathe
- Manual mill
- Pillar drills
Working Hours / Shift Pattern
- Standard working week: 40 hours, Monday to Friday.
- Early shift: 06:00–15:00 (30 mins lunch + two 15 min breaks). Breaks taken at Section Head discretion to achieve best output.
- Potential late shift requirement (to be discussed): 14:00–01:00 Monday to Thursday (30 mins lunch + two 15 min breaks). Breaks taken at Section Head discretion to achieve best output.
Working Conditions & Physical Requirements
- Workshop/manufacturing environment (standing for long periods, manual handling of tooling/fixtures within safe limits, PPE required).
- Must follow safe systems of work and quality processes suitable for aerospace/composites production.
