CNC Horizontal Boring Bar Machinist

Step into a role where your craft runs the show. As a CNC Horizontal Boring Bar Machinist, you’ll operate large-scale CNC boring equipment to translate blueprints into finished components—on time, to spec, and to the highest standards of quality and throughput.

You clock in and review process sheets and component drawings. You preset CNC tooling, load program tapes/files, and make on-machine edits as needed. With cranes and jib hoists certified under your belt, you rig the job safely—chains, slings, battery magnet at the ready—then bring the spindle to life. Throughout the run, you verify dimensions with precision metrology, log paperwork that travels with each part, and perform random ISO-driven inspections. Between cycles, you keep the area 5S clean, touch up small twist drills on the grinder, and prep the next setup so production never misses a beat.

• Set up and run large CNC boring bars to blueprint and process sheet requirements.
• Load tapes/files and edit CNC programs to optimize part quality and takt time.
• Read and work from drawings, schematics, mini process sheets, and detailed dimensions.
• Use rules, levels, miters, and squares to verify angles and features.
• Operate internal shapers and perform presetting for CNC tooling.
• Grind small twist drills and maintain sharp, reliable tooling.
• Operate small hand and power tools; use precision measuring devices.
• Receive and maintain company certification to operate overhead cranes, jib hoists, and powered industrial forklifts.
• Perform daily equipment checks and basic rigging with chains and slings for jib/overhead cranes and battery magnets.
