Job Summary

We are seeking a highly skilled Precision Horizontal Boring Mill Machinist with experience operating Wotan Horizontal Boring Mills, including models B-1305, B-105M, B-1005, and/or 340RT. This position is responsible for setting up and machining complex, high-value components to extremely tight tolerances. The ideal candidate brings strong blueprint-reading and GD&T knowledge, advanced inspection skills, and the ability to independently align, indicate, machine, and verify precision parts where every thousandth matters.

Responsibilities

• Independently set up, align, and operate horizontal boring mill equipment for precision-machined components
• Machine parts to tight tolerances, including bore locations, diameters, flatness, perpendicularity, and true position requirements
• Read and interpret detailed engineering drawings, GD&T callouts, inspection reports, and work instructions
• Determine machining strategy, work holding methods, tooling, cutting parameters, and setup sequence
• Perform precision boring, milling, drilling, facing, and related machining operations
• Verify part quality throughout the machining process using calibrated precision measuring equipment
• Use micrometers, dial indicators, bore gauges, height gauges, depth gauges, and other inspection tools to confirm dimensions
• Make accurate machine adjustments and offsets to maintain repeatability and meet print specifications
• Identify tooling, setup, material, or program issues before they become expensive scrap
• Maintain a clean, organized, and safety-focused work area

Qualifications

• 10+ years of horizontal boring mill experience in a precision-machining environment
• Proven ability to hold very tight tolerances, ideally within ±.001 or tighter depending on part requirements
• Strong understanding of GD&T, datum structures, alignment, concentricity, perpendicularity, and positional tolerancing
• Experience setting up and machining complex, high-value, low-volume, or large-scale components
• Advanced blueprint-reading and precision inspection skills
• Ability to work independently, troubleshoot problems, and document inspection results accurately
• High attention to detail, strong math skills, and a quality-first mindset
