DESCRIPTION:
Aluminum Finishing Expert focus on deburring and post‑machining part refinement. Must understand a production environment, safety culture, and quality expectations, and is ready to apply their hands-on finishing expertise to support semiconductor‑grade aluminum component manufacturing. Ensure aluminum components meet the strict cleanliness, precision, and performance standards required for semiconductor equipment.
KEY RESPONSABILITIES:
-
Perform detailed deburring of CNC‑machined aluminum parts, including removal of sharp edges, burrs, tool marks, and micro‑burrs using hand tools, rotary tools, abrasive pads, files, scrapers, and specialty deburring equipment.
-
Refine and prepare surfaces to meet semiconductor‑grade specifications, including smoothing edges, blending surfaces, and ensuring consistent cosmetic appearance.
-
Inspect machined features (chamfers, radii, pockets, threads, sealing surfaces) to verify they meet internal standards before parts move to finishing or cleanroom processing.
-
Identify and correct machining‑related defects such as chatter marks, burr buildup, surface inconsistencies, or incomplete toolpath transitions.
-
Collaborate with CNC machinists and engineering to communicate recurring burr issues, tolerance concerns, or opportunities to improve manufacturability.
-
Perform precision cleaning and pre‑finish preparation, including degreasing, ultrasonic cleaning, masking, and controlled surface conditioning.
-
Support anodizing and conversion coating processes by ensuring all parts are properly prepped, free of contamination, and meet surface roughness requirements.
-
Use inspection tools such as microscopes, magnifiers, profilometers, calipers, and gauges to verify surface quality and dimensional accuracy.
-
Maintain documentation including part travelers, inspection records, and traceability logs.
-
Follow all semiconductor cleanliness and contamination‑control protocols, leveraging existing knowledge of our facility’s standards.
-
Contribute to continuous improvement by identifying ways to reduce rework, improve consistency, and streamline deburr workflows.
