Jobbeschreibung

Granite State Manufacturing is a leading contract manufacturer of large, complex, precision machined and welded components, supporting the US Navy in building submarines.

We specialize in high-mix, low-to-medium volume production, delivering precision, quality, and on-time performance on custom-engineered products. Our capabilities include:

• Large-format CNC machining
• Heavy fabrication and welding (MIG, TIG, FCAW, SAW)
• Assembly, inspection, and testing
• Program management for complex builds

We are known for handling tight tolerances, complex geometries, and demanding customer specifications.

Our work environment is supportive, providing what our people need to do great work.

Position Summary

The Manual / ProtoTRAK Machinist is responsible for setting up and operating manual mills, lathes, and ProtoTRAK-controlled machine tools to produce large, close-tolerance components and assemblies in a high-mix, low-volume manufacturing environment. This position supports the production of large CNC-machined and welded components for government and defense applications where quality, precision, repeatability, and strict adherence to specifications are essential.

The successful candidate will be comfortable interpreting engineering drawings, specifications, work instructions, and GD&T; selecting appropriate tooling and workholding; making machine adjustments and offsets; and independently determining the most effective machining approach for one-off and small-batch work.

ESSENTIAL FUNCTIONS AND RESPONSIBILITIES

• Set up and operate manual and ProtoTRAK mills, lathes, and related machine tools to produce precision components.

• Machine large, heavy, and complex parts from steel, stainless steel, aluminum, and other common engineering materials.

• Read and interpret engineering drawings, blueprints, GD&T, process sheets, job travelers, and customer specifications.

• Determine machining sequences, workholding methods, tooling, speeds, feeds, and cutting strategies based on part requirements.

• Perform first-piece and in-process inspections using precision measuring equipment such as micrometers, calipers, bore gauges, height gauges, indicators, and other inspection tools.

• Make necessary machine adjustments, tool changes, and dimensional corrections to maintain part requirements.

• Use ProtoTRAK conversational programming to develop, modify, and execute machining programs.

• Perform manual machining operations when required, including turning, facing, boring, drilling, tapping, milling, reaming, and related operations.

• Set up and machine parts to specified dimensions and tolerances, including close-tolerance and geometric requirements.

• Safely rig, position, and secure large workpieces using cranes, hoists, lifting fixtures, and appropriate workholding equipment.

• Collaborate with CNC machinists, welders, fabricators, quality personnel, engineering, and manufacturing leadership to resolve production issues.

• Identify tooling, fixturing, material, drawing, or process problems and recommend practical solutions.

• Deburr, clean, and prepare completed components for inspection or subsequent manufacturing operations.

• Complete required production documentation, inspection records, job travelers, and timekeeping accurately.

• Maintain a clean, organized, and safe work area and follow all applicable safety requirements.

• Protect controlled, proprietary, and customer-sensitive information in accordance with company procedures and applicable contract requirements.

• Support continuous improvement efforts involving machining methods, setup reduction, tooling, quality, productivity, and safety.
