• Machine medium-sized, square or rectangular parts for large control flow valves, focusing on top milling, facing, and drilling operations.
• Handle parts ranging from approximately 15–25 inches outer dimension and 30–1,000 pounds in weight, using appropriate fixturing and handling methods.
• Perform full machine setups, including tooling, workholding, and program loading, to ensure accurate and efficient production.
• Make program edits as needed using G and M codes to optimize machining performance and maintain part quality.
• Maintain dimensional accuracy by machining to tolerances of approximately ±0.001 inch.
• Cross-train to run a standard CNC lathe with Fanuc controls and operate it as needed to support production.
• Inspect parts during and after machining to verify conformance to specifications and make adjustments as required.
• Monitor machine performance, troubleshoot issues, and communicate any mechanical or quality concerns promptly.
• Follow all safety procedures and maintain a clean, organized work area within the shop.

• Proficiency with G and M codes and their application to CNC milling operations.
• Hands-on experience with CNC milling machines and vertical machining centers.
• Experience operating or familiarity with CNC lathes.

Additional Skills & Qualifications

• Experience running Johnford, HNK, or SNK vertical mills is a strong plus.
• Prior experience operating a Toshiba BP 150 horizontal boring mill with Tosnuc controls is beneficial.
• Previous exposure to machining medium-sized, heavy components such as valve or industrial equipment parts.
• Comfort working with large workpieces and using appropriate lifting and handling equipment.
• Willingness to cross-train on additional machines and expand technical capabilities over time.
