Cnc Machinist - Kearny Mesa

The CNC Machinist III sets up and operates computer numerical control (CNC) equipment, including lathes, mills, and vertical turning lathes (VTL), to produce precision metal parts and materials. This role interprets blueprints and technical specifications to determine dimensions, tolerances, and sequences of operations, and executes complex machining assignments on multi‑axis machines. The CNC Machinist III follows routers and technical planning documents, adheres to established specifications, and uses precision measuring tools to verify the accuracy and quality of finished components.

• Set up, adjust, and operate CNC machine controls to position tools and regulate cutting depth, speed, feed, and coolant flow in order to produce precision metal parts and materials according to work orders, blueprints, drawings, templates, and layouts.

• Mount, align, and secure tooling, attachments, and work pieces on machine chucks or fixtures, ensuring proper clamping and positioning for safe and accurate machining.

• Start and stop automatic operation of numerical control machines, perform test setups, and verify workpiece dimensions and programming before and during production runs.

• Monitor machines during operation to diagnose malfunctions, identify the need for adjustments or repairs, and make appropriate changes to machine controls when automatic programming is faulty or equipment issues arise.

• Perform routine machine maintenance such as checking coolant levels, confirming proper machine positioning, and ensuring equipment remains in good working order.

• Ensure finished parts meet specified dimensions and tolerances, verifying conformance to engineering and quality requirements using appropriate measuring devices.

• Clean machines, tooling, parts, and the surrounding work area in accordance with 5S procedures to maintain a safe, organized, and efficient workspace.

• Demonstrate reliability by appearing for work on time, following directions, collaborating effectively with co‑workers, and consistently adhering to work rules, procedures, corporate policies, goals, and objectives.

• Accept constructive feedback, show initiative, and exhibit a strong commitment to quality, safety, and continuous improvement in daily work.

• Participate in Daily Management board meetings and engage in discussions related to Safety, Quality, Delivery, Efficiency, and Utilization.

• Proactively identify opportunities to improve machining processes and contribute to continuous improvement activities to enhance productivity and quality.

• Read and interpret blueprints, drawings, and templates, including dimensional, true position, and circularity callouts, to plan and execute machining operations.

• Set up fixtures properly, including clamping, centering, and indicating, to ensure accurate and repeatable part positioning.

• Set up cutting tools, change inserts for cutting operations, and verify that tooling is appropriate for the material and machining requirements.

• Use calipers, micrometers, bar gauges, and other measuring devices to inspect parts and confirm that all critical dimensions and tolerances are met.

• Control the operation of equipment by monitoring gauges, dials, and other indicators to ensure machines are running correctly and safely.

• Minimum 2 years of previous CNC machine setup and operation experience or equivalent experience, with openness to candidates who have less experience but are highly motivated to learn and work hard.

• Proven ability to set up and operate CNC lathes, mills, and vertical turning lathes (VTL) for precision machining.

• Ability to read and interpret basic blueprints, drawings, and templates,…
