• Work from engineering drawings, blueprints, and manufacturing routers to plan and execute machining operations.
• Independently perform complete machine setups, including selecting tooling, setting work offsets, and establishing machine parameters.
• Interpret blueprints and engineering drawings to determine dimensions, tolerances, and machining sequences.
• Machine valve bodies, wellhead equipment, pressure-containing components, and other critical assemblies.
• Perform tight-tolerance machining and maintain dimensional accuracy throughout production runs.
• Use precision measuring instruments and inspection tools to verify dimensions and tolerances.
• Conduct in-process and final quality inspections and perform tolerance testing on machined parts.
• Make machine offsets and adjustments to correct dimensional deviations and optimize part quality.
• Troubleshoot machining issues, including tooling wear, chatter, dimensional variance, and surface finish problems.
• Handle and position large forgings, castings, and heavy workpieces using overhead cranes and other material-handling equipment.
• Follow established manufacturing routers, shop procedures, and quality standards for oilfield equipment manufacturing.
• Maintain a clean, safe, and organized work area in a heavy manufacturing machine shop.
• Collaborate with engineering, quality, and production teams to ensure throughput, accuracy, and on-time delivery.
• Support a fast-paced production environment by meeting production targets while maintaining high quality.
