S. company that custom designs, manufactures and supports hydraulic press systems for molding rubber and composite materials, screw presses for synthetic rubber processing and for the separation of liquids from solids, and oilseed equipment used to extract vegetable oil from seeds and nuts, and to produce biofuels.

For over 120 years we have partnered with our stakeholders, in over 80 countries worldwide, to provide products with superior value and superior service that improve our customers’ productivity and reduce their overall production costs.

Position Summary: We are seeking an experienced CNC Horizontal Boring Mill Machinist to set up and operate CNC horizontal boring and milling equipment for large castings, weldments, housings, frames, and other precision components. The ideal candidate can establish datums, align and fixture large work pieces, and machine bores, faces, holes, and patterns with strong control of size, position, and coaxiality. This role requires confidence with boring bars and related tooling, disciplined management of tool offsets and machine setup, and close collaboration with quality and engineering on first‑piece approval and process improvement.

It is a strong fit for a machinist who has moved beyond general CNC operation into large‑part setup ownership and bore geometry control.

Essential Duties and Responsibilities:

• Set up and operate CNC horizontal boring/milling equipment to machine large precision parts from first setup through final verification.
• Interpret blueprints, router instructions, dimensions, and tolerances to establish machining sequence, datum structure, and setup strategy.
• Align and secure large work pieces using machine tables, T‑slots, angle plates, blocks, fixtures, clamps, and other heavy work holding methods appropriate to the part.
• Perform precision boring, milling, drilling, reaming, tapping, facing, and hole‑pattern work on castings, weldments, housings, frames, and related components.
• Utilize part probe and tool probe systems to establish work coordinates, verify setup accuracy, measure tooling, and support first‑piece and in‑process inspections.
• Select and manage tooling such as boring bars, boring heads/facing heads, drills, reamers, taps, shell mills, end mills, and indexable cutting tools.
• Adjust speeds, feeds, tool offsets, cutter compensation, and program details to maintain bore size, straightness, coaxiality, and positional accuracy.
• Conduct first‑piece and in‑process inspection using micrometers, bore gages, indicators, height gages, gage blocks, and other precision inspection tools.
• Work with quality and manufacturing engineering to confirm process capability, resolve dimensional concerns, and improve setup efficiency or repeatability.
• Support safe handling of large parts, fixtures, and accessories in coordination with appropriate lifting and rigging practices.
• Maintain clean, organized work areas and assist with machine/tooling upkeep and process documentation.

Qualifications and

Experience:

• Minimum 5 years of machining experience, with at least 3 years on CNC horizontal boring mills, large CNC mills, or similarly demanding large‑part machining platforms.
• Proven ability to read blueprints, sketches, CAD‑based drawings, and written instructions and translate them into reliable multi‑step boring/milling setups.
• Strong understanding of boring‑machine process basics, including use of boring bars, tool extension limits, rigidity, vibration awareness, and size adjustment strategy.
• Experience machining large parts that require setup precision, hole‑location control, bore alignment, or multiple datums in one or more setups.
• Working knowledge of CNC controls and editing practices. Common industrial controller families include Fanuc, Siemens, Heidenhain, Mazak, Okuma, and Haas variants.
• Ability to perform first‑piece inspection and work effectively with quality for process verification and approval.
• Experience in a job‑shop environment with changeovers, varied work content, and shifting priorities.
