Core Responsibilities

Primary Functions

Operate various hand-held power grinders, including angle, die, and pencil grinders, to smooth, shape, and finish metal surfaces according to specifications.
Meticulously remove excess material, such as weld spatter, burrs, slag, and rust from parts and assemblies.
Read and interpret blueprints, work orders, and engineering drawings to understand grinding requirements, dimensions, and finish specifications.
Select and properly install appropriate abrasive wheels, discs, belts, and other attachments based on the material type and desired surface finish.
Conduct visual and dimensional inspections of workpieces using calipers, gauges, and other measuring tools to ensure conformance to quality standards.
Adhere strictly to all company and OSHA safety protocols, consistently using Personal Protective Equipment (PPE) such as face shields, safety glasses, respirators, and steel-toed boots.
Set up and secure workpieces using clamps, jigs, fixtures, or vises to ensure stability and safety during the grinding process.
Perform routine pre-use inspections and basic maintenance on grinding tools and equipment to ensure they are in safe, working order.
Blend and feather ground surfaces to create a smooth, seamless transition, particularly on welded joints and repaired areas.
Maintain a clean, organized, and safe work area, embracing lean manufacturing principles like 5S.
Work effectively with a variety of metals, including carbon steel, stainless steel, aluminum, and other alloys, understanding how each material responds to grinding.
Monitor the grinding process vigilantly to prevent overheating, warping, or compromising the structural integrity of the workpiece.
Utilize other finishing tools as needed, such as sanders, polishers, and buffers, to achieve a specified surface texture or polish.
Accurately complete production documentation, including work logs, time sheets, and inspection reports.
Communicate clearly and effectively with supervisors, welders, and quality assurance personnel regarding project status, material defects, or any production issues.
Grind parts to precise dimensional tolerances, ensuring they will fit correctly in subsequent assembly stages.
Prepare metal surfaces for downstream processes like painting, powder coating, or plating by creating the required surface profile.
Identify and report any equipment malfunctions, safety hazards, or potential quality issues to the team lead or supervisor immediately.
Safely operate material handling equipment, such as overhead cranes or pallet jacks, to move heavy parts and materials as required.
Chamfer and deburr sharp edges on finished parts to ensure safety during handling and proper fit during assembly.

Secondary Functions

Assist in the cross-training of new team members on basic grinding techniques and safety procedures.
Participate actively in team safety meetings and contribute to continuous improvement initiatives aimed at enhancing quality and productivity.
Help manage and track inventory of consumable supplies like grinding discs, abrasives, and PPE.
Support adjacent departments by performing minor fabrication or assembly tasks when primary duties are complete.
