Aluminum Finishing Expert

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 Responsibilities

• 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.

• Ability to work with small, intricate, or tight-tolerance features common in semiconductor components.
• Familiarity with aluminum machining characteristics, burr formation, and best practices for manual and mechanical deburring.
• Understanding of cleanroom and contamination-control requirements.
• Ability to read and interpret technical drawings, GD&T, and surface finish specifications.
• High attention to detail, strong hand-eye coordination, and a commitment to producing defect-free parts.
• Knowledge of chemical safety, PPE requirements, and safe handling of parts destined for high-purity processes.

Education and/or Experience Required

• Experience deburring components used in semiconductor process equipment, vacuum systems, or high-purity assemblies.
• Familiarity with advanced surface inspection tools or semiconductor-specific metrology.
• Experience supporting anodizing, conversion coating, or other aluminum finishing processes.
• Background in lean manufacturing, 5S, or continuous improvement.
• Ability to train others in deburring techniques and finishing standards.
• Minimum 5 years of experience in semiconductor, aerospace, precision aluminum hand finishing/Deburr or related manufacturing environment.
• Strong knowledge of safety procedures, quality standards, and industry best practices.
• Ability to communicate clearly with employees at all levels (written and verbal).
• Strong organizational skills and adaptability in a high-mix, precision manufacturing environment.
• Ability to coach, mentor, and motivate employees in both group and one-on-one settings.
• High school diploma, GED equivalent.

• Excellent verbal, written, and interpersonal communication skills.
• Ability to communicate with others clearly and concisely both verbally and in writing.
• Ability to perform daily tasks with little or no supervision.
• Proficient in Microsoft Office (Excel, Word, Outlook).

Physical Demands While Performing the Job

• Standing for extended periods of time, sitting or standing, walking, pushing, pulling, stooping, kneeling, or bending to the floor; use hands to finger, handle or feel parts and materials; reach with hands and arms and overhead; and talk and/or hear instructions and equipment sounds.
• Occasionally lifting and/or moving items up to 40 pounds.
• Close vision, color vision, depth perception, and ability to adjust focus.
• Ability to differentiate shades and color to identify coating defects.
• Near acuity or accommodation required for reading instrumentation and documentation, dial and digital gauges, blueprints, and precision measuring instruments used in the inspection of coating operations.
• Ability to handle delicate parts.

Working Environment of the Job

• Regularly exposed to moving equipment, mechanical parts, ovens, and risk of burns.
• Occasionally exposed to toxic or caustic chemicals and risk of electrical shock.
• High noise levels from operating machines.
• The employee will be required to use personal protective equipment (PPE) to prevent exposure to hazardous materials commonly used in a manufacturing environment (i.e., safety glasses and shoes, gloves, ear plugs/covers, mask, cleanroom suit).
• Physical hazards while working near moving equipment and mechanical parts.
• Possible breathing of fumes, odors, dust, and mist.
• Ability to work in a manufacturing environment involving machinery, chemicals, PPE, and standing for extended periods.
