What are the responsibilities and job description for the CNC MACHINE OPERATOR position at Phoenix Defense?
The CNC Machine Operator is responsible for safely operating a dedicated CNC machining cell to produce aerospace components that meet print and quality requirements in a fast-paced production environment.
The CNC Machine Operator sets up and runs a CNC machining cell consisting of pre-set lathes and mills to manufacture aerospace components in a high-volume production environment. This role loads and unloads parts across multiple machines, performs in-process dimensional inspections using precision measuring tools, and monitors tool wear to replace inserts and cutting tools within defined guidelines. The operator is accountable for maintaining consistent part flow, supporting cell uptime and 5S standards, and escalating machine, quality, or tooling issues to engineering or programming as needed. The CNC Machine Operator follows detailed work instructions, inspection plans, and quality documentation to ensure all parts meet print specifications and adhere to internal quality standards prior to release to the next operation.
