Job Description

Industry: Precision Manufacturing / Power Transmission ComponentsEmployment Type: Full-Time

A well-established, privately held manufacturer specializing in large, high-precision mechanical components is seeking an experienced CNC Machinist to join its machining team. This organization has built a strong reputation in the heavy industrial power transmission sector and continues to invest in advanced machining technologies to support complex, large-scale components for demanding applications.

This role is ideal for machinists who enjoy complex setups, large workpieces, and precision machining in a job-shop or low-volume environment rather than high-volume production work.

Key Responsibilities

  • Set up and operate large CNC machine tools including horizontal boring mills, vertical turret lathes, large vertical mills, or multi-axis machining centers

  • Perform machining operations on large mechanical components such as rings, shafts, housings, and precision rotating parts

  • Interpret complex blueprints, GD&T, and technical drawings

  • Perform machine setup, tool selection, offsets, and program edits as required

  • Maintain tight tolerances on large parts and verify dimensions using precision inspection tools

  • Work collaboratively with engineering and quality teams to ensure parts meet specifications

  • Support continuous improvement and safe machining practices within the shop

Preferred Qualifications

  • 5+ years of CNC machining experience

  • Experience machining large components or heavy parts

  • Background with horizontal boring mills, VTLs, or large multi-axis mills

  • Ability to perform full setups and adjust programs

  • Strong understanding of precision measurement tools and inspection methods

  • Experience in job shop, heavy industrial, or custom manufacturing environments

Highly Desired Experience

  • Gear manufacturing exposure (gear hobbing, shaping, or gear finishing)

  • Multi-axis machining experience

  • CAM programming exposure

  • Experience machining tight-tolerance rotating components

What Makes This Opportunity Attractive

  • Stable, long-standing privately held manufacturing company

  • Complex and interesting machining work (not repetitive production)

  • Significant investment in advanced machining technology

  • Opportunity to work on large, high-precision industrial components

  • Competitive compensation and strong benefits package

This role is ideal for machinists who take pride in precision craftsmanship, complex setups, and machining large critical components used in demanding industrial applications.

Qualified candidates with strong machining backgrounds in heavy equipment, power generation, mining equipment, steel industry components, or large job shop environments are strongly encouraged to apply.
