Duties & Responsibilities:
o Minimum 10 years of hands-on experience operating CNC boring mills in a heavy machining environment.
o Review and interpret engineering drawings, job travellers, work orders, specifications, sketches, and GD&T requirements prior to machining operations.
o Set up, program, and operate CNC boring mills with minimal supervision in a safety-focused manufacturing environment.
o Machine large-scale and complex components weighing up to 2000lbs while maintaining dimensional accuracy and geometric tolerances.
o Perform machining operations including boring, drilling, milling, facing, tapping, and fitting as required by production demands.
o Conduct complete machine setups, including tooling alignment, work holding verification, reference point establishment, and pre-machining inspections.
o Modify and optimize CNC programs, tool offsets, feeds, speeds, and cutting parameters to achieve required tolerances, surface finishes, and cycle time efficiencies.
o Perform CNC program prove-outs and first-off inspections to validate machining accuracy and process reliability.
o Read, interpret, and edit manual CNC programs; experience with Heidenhain and Fanuc controls preferred.
o Maintain machining tolerances through continuous in-process inspections, offset corrections, and tooling adjustments.
o Utilize precision measuring instruments to inspect and record critical dimensions in accordance with quality standards.
o Ensure compliance with ISO standards, customer specifications, and internal quality management procedures.
o Identify, document, and report non-conformances; support root cause analysis and corrective action implementation.
o Maintain accurate production records, including part traceability, work order documentation, and material identification.
o Complete setup sheets and process documentation for new product approvals and production continuity.
o Identify opportunities for continuous improvement related to machining efficiency, tooling performance, and process optimization.
o Operate overhead cranes and forklifts safely for handling and positioning large components in coordination with rigging personnel.
o Perform routine machine inspections, preventive checks, and basic troubleshooting to maintain equipment reliability.
o Maintain a clean, organized, and safe work environment in compliance with 5S practices and housekeeping standards.
o Adhere to all company safety policies, PPE requirements, safe rigging procedures, and applicable CCOHS and WHMIS regulations.
o Strong mechanical aptitude and problem-solving skills with the ability to work independently in a high-precision manufacturing environment.
o Hands-on experience with 5-axis gantry machining centers is considered a strong asset.
o Willingness to undergo training on additional CNC control systems and machining technologies as required
