Job Title: CNC Machinist Job Description

This role involves setting up and operating a variety of CNC machines in a manufacturing environment, performing full machine setups, and conducting precise in-process inspections to ensure high-quality parts. The position requires strong blueprint reading skills, accurate use of measuring instruments, and the ability to work efficiently on short runs and small batch production.

Responsibilities

• Set up and operate various CNC machines, including mills and lathes, to produce precision components.
• Perform full machine setups, including changing jaws, installing and adjusting tooling, and touching off tools.
• Select and load programs from the program library and follow detailed setup sheets provided for all parts.
• Run short production runs and small batch jobs, often completing multiple setups per day.
• Maintain and work to typical tolerances of approximately .002 to .005 inches, and tighter tolerances around .0005 inches for bearing turns and bearing pockets.
• Perform first piece inspections to verify that initial parts meet all specifications before continuing production.
• Conduct in-process inspections using gauges and other measuring instruments to ensure parts remain within specified tolerances throughout the run.
• Use measuring instruments such as calipers, outside and inside micrometers (OD/ID mics), and depth micrometers to verify dimensions.
• Read and interpret blueprints and written work instructions to determine machining operations, sequence, and dimensions.
• Follow established work instructions and quality procedures to ensure consistent and repeatable results.
• Maintain a clean and organized work area and handle equipment and tools with care.
• Collaborate with team members and communicate any issues related to quality, equipment, or process.
