Assembly Technician- Impeller Trimming

About the role

Job Summary We are seeking a skilled and detail-oriented Assembly Finishing Technician to join our manufacturing team. In this role, you will be responsible for the final blending, grinding, and polishing of cast pump impellers. Using a variety of pneumatic (air) hand tools, you will remove excess material, establish precise geometric radii, and achieve specified surface finishes critical to fluid dynamics and pump efficiency. Key Responsibilities Precision Grinding: Operate various air-powered grinding tools, die grinders, and polishing equipment to blend and finish internal and external impeller vanes. Blueprint & Spec Compliance: Read and interpret technical drawings, blueprints, and engineering specifications to ensure all contours, radii, and surface finishes meet strict tolerances. Quality Inspection: Use precision measuring instruments (such as radius gauges, calipers, and surface roughness testers) to self-inspect work and ensure quality compliance. Defect Removal: Identify and eliminate casting defects, burrs, sharp edges, and parting lines without compromising the structural integrity of the component. Equipment Maintenance: Perform routine daily maintenance on pneumatic tools, including oiling, changing out abrasive wheels/burrs, and reporting mechanical issues. Safety & Housekeeping: Maintain a clean, organized workstation and strictly adhere to all safety protocols, including the mandatory use of PPE (respirators, hearing protection, and face shields). Impeller Balancing : Execute single- and two-plane balancing of impellers to meet specified balance quality grades and customer requirements. Analyze imbalance conditions and apply corrective grinding while maintaining geometric integrity of critical features. Qualifications & Skills Experience: 1-3 years of experience in metal finishing, deburring, or precision grinding within a foundry, aerospace, or heavy machinery manufacturing environment. Tool Proficiency: Proven expertise using pneumatic die grinders, angle grinders, pencil grinders, and various abrasive media (carbide burrs, flap wheels, scotch-brite pads). Technical Literacy: Ability to read blueprints and understand geometric dimensioning and tolerancing (GD&T) related to radii and surface finishes (e.g., Ra values). Dexterity & Detail: High level of manual dexterity, hand-eye coordination, and a keen eye for visual defects. Education: High school diploma or equivalent; technical certification in welding, machining, or manufacturing is a plus. Physical Requirements Ability to stand, bend, and reach for extended periods (8+ hour shifts). Capability to lift and maneuver components weighing up to 50 lbs.
