What is a horizontal boring mill operator?

Horizontal Boring Mill Operators are skilled machinists who set up, operate, and maintain horizontal boring mills—a type of large industrial machine used to bore holes or enlarge openings in metal workpieces. They interpret blueprints, adjust machine settings, and ensure precision in machining processes. These operators are essential in manufacturing industries such as aerospace, automotive, and heavy equipment, where large and complex parts require accurate drilling and finishing. Their role also involves routine inspection and maintenance of machinery to guarantee safe and efficient operation.

What does a horizontal boring mill operator do?

As a horizontal boring mill operator, your duties and responsibilities are to operate drilling machines, which bore, mill, or ream holes in metal, plastic, or other fabricated materials meant to assemble into larger components. You may drill different kinds of holes, such as countersink holes, which can be covered up upon assembly. As the operator, you are responsible for machine set-up, its operation, and the maintenance of tools and equipment. You must also adhere to all relevant safety guidelines at your job site.

What are the key skills and qualifications needed to thrive as a horizontal boring mill operator, and why are they important?

To thrive as a Horizontal Boring Mill Operator, you need mechanical aptitude, precision measurement skills, and experience with machining principles, often supported by a technical diploma or apprenticeship. Familiarity with CNC controls, blueprint reading, and the operation of manual and computerized boring mill equipment is typically required. Attention to detail, problem-solving abilities, and effective communication are vital soft skills for maintaining safety and quality standards. These skills ensure accurate machining, minimize errors, and promote efficient teamwork in a manufacturing environment.

What are some common challenges faced by horizontal boring mill operators, and how can they be addressed?

Horizontal Boring Mill Operators often face challenges such as maintaining tight tolerances on large, heavy workpieces and ensuring equipment is properly aligned. These tasks require attention to detail, strong troubleshooting skills, and the ability to interpret complex blueprints. Collaboration with other machinists, maintenance teams, and quality inspectors is common to address issues quickly and keep production on schedule. Regular training on machine operation and safety protocols can help operators stay efficient and avoid costly errors or downtime.

What is the difference between Horizontal Boring Mill Operator vs Vertical Boring Mill Operator?

AspectHorizontal Boring Mill OperatorVertical Boring Mill Operator
CredentialsTypically requires machining certifications or technical trainingSimilar certifications, often overlapping with horizontal operators
Work EnvironmentOperates horizontal boring mills in manufacturing or machine shopsOperates vertical boring mills in similar settings
Industry UsageCommon in heavy machinery, aerospace, and automotive manufacturingUsed in similar industries for precise large-part machining

Both Horizontal Boring Mill Operators and Vertical Boring Mill Operators require technical skills and certifications in machining. They work in similar environments and industries, often performing comparable tasks with different machine orientations. The main difference lies in the type of boring mill they operate, which influences the machining process and the types of parts they produce.

About ACME Industries

ACME Industries is a 70+ year aerospace and defense manufacturer headquartered in Elk Grove Village, IL. We own and solve complex problems — manufacturing precision solutions for mission-critical, long-life applications across the industries that matter most. We are financially healthy, growing, and investing in the people and capabilities that will carry us to the next chapter.

Position Summary: Second Shift CNC Bore Mill Machinist

The CNC Bore Mill Machinist is a skilled, experienced operator responsible for the setup, operation, and quality verification of CNC horizontal boring mill equipment. This role is critical to ACME's production capacity and supports the second-shift execution of precision components for aerospace, defense, and industrial customers. The right candidate brings deep machine knowledge, a self-sufficient approach to setup and troubleshooting, and the discipline to hold tight tolerances on complex, high-value parts.

Essential Responsibilities
  • Set up and operate CNC horizontal boring mills to produce precision components from engineering drawings, routers, and work orders
  • Select and install tooling, fixtures, and workholding equipment appropriate to the job
  • Perform in-process and final inspection using precision measurement tools (micrometers, bore gauges, CMM where applicable)
  • Read and interpret GD&T, blueprints, and shop travelers with accuracy
  • Monitor feeds, speeds, and tool wear; make offsets and adjustments to maintain tolerances
  • Identify and resolve machine alarms, tooling issues, and surface condition problems independently
  • Maintain accurate production records, first-article documentation, and non-conformance reports as required
  • Follow all safety, quality, and housekeeping standards; support 5S on the shop floor
  • Collaborate with day-shift operators and production management to ensure smooth shift transitions and workload continuity
  • Participate in cross-training and knowledge transfer activities as the operation grows
Qualifications

Required:

  • Ability to work second shift consistently starting at 4:00 PM Monday through Friday with Voluntary Overtime available
  • 5+ years of hands-on CNC boring mill experience (horizontal boring mill preferred)
  • Demonstrated ability to set up jobs independently — not operator-only experience
  • Proficiency reading blueprints and GD&T
  • Experience with precision measurement and inspection

Preferred:

  • Experience in aerospace, defense, or heavy industrial manufacturing
  • Familiarity with FANUC controls
  • Exposure to AS9100 or ISO quality management systems
  • Experience machining large, complex, low-volume parts
What We Offer
  • Competitive hourly wage commensurate with experience
  • Comprehensive benefits including medical, dental, vision, and 401(k)
  • A stable, growing company with 70+ years of history and a long-term ownership mindset
  • Investment in your development — we build careers, not just headcounts

  • GD&T
  • Equipment Troubleshooting
  • CNC Tooling
  • Troubleshooting Skills
  • CNC Programming
  • G-Code
  • Precision Measurement & Hand Metrology
  • Advanced Inspection & Gauge Measurement
