Core Responsibilities

Primary Functions

Operate a variety of grinding and polishing equipment, including pedestal grinders, belt sanders, and handheld pneumatic tools, to shape and smooth metal surfaces.
Meticulously read and interpret blueprints, work orders, and engineering specifications to fully understand the required surface finish, dimensions, and quality standards.
Select the appropriate abrasives, buffing wheels, polishing compounds, and tools based on the type of metal (e.g., stainless steel, aluminum, titanium) and the desired finish.
Systematically remove surface defects such as scratches, pits, excess weld material, and burrs from metal parts to prepare them for final polishing.
Perform detailed hand-polishing and lapping on intricate, complex, or delicate components that require a high degree of manual dexterity and control.
Conduct in-process and final visual inspections to identify any imperfections and ensure a uniform, high-quality finish across the entire workpiece.
Utilize precision measuring instruments, including micrometers, calipers, and profilometers, to verify that parts conform to dimensional tolerances post-polishing.
Expertly blend and feather reworked or repaired areas to seamlessly match the surrounding surface finish, making corrections virtually undetectable.
Set up, adjust, and perform routine maintenance on polishing and grinding machinery to ensure optimal performance, safety, and longevity.
Adhere strictly to all company and industry safety protocols, including the consistent and correct use of personal protective equipment (PPE) such as respirators, safety glasses, and protective gloves.
Maintain a clean, organized, and safe work environment by following 5S principles and participating in regular shop housekeeping duties.
Document all work performed, including completing production logs, quality control sheets, and tracking time spent on each job order accurately.
Collaborate effectively with machinists, welders, and quality assurance personnel to troubleshoot finishing issues and ensure a smooth, efficient production workflow.
Carefully handle and transport high-value, delicate, or heavy components using appropriate methods and equipment to prevent damage or injury.
Monitor the inventory of polishing supplies and consumables, such as abrasive belts, discs, and compounds, and proactively report replenishment needs to the supervisor.
Prepare and clean finished parts, ensuring they are free of debris and polishing residue before they move to the next stage of production or packaging.
Apply different finishing techniques, which may include tumbling, sandblasting, or vibratory finishing, to achieve specific textures and appearances.
Contribute to continuous improvement initiatives by identifying and suggesting process enhancements that can increase efficiency, improve quality, or enhance safety.
Train and mentor junior polishers or apprentices, sharing knowledge of best practices, proper techniques, and critical safety standards.
Work independently with minimal supervision to meet demanding production schedules and deadlines while consistently maintaining high-quality output.

Secondary Functions

Assist in other production areas or departments as needed to support team goals and meet fluctuating manufacturing demands.
Participate in routine equipment cleaning and preventive maintenance tasks to minimize downtime and ensure operational readiness.
Contribute to team meetings and quality discussions, providing valuable feedback from a finishing perspective.
Help maintain the overall cleanliness and organization of the shop floor beyond the immediate workstation.
