About The Position

We are seeking an experienced Lead Swiss CNC Set-up Machinist to be responsible for independently setting up, troubleshooting, and supporting the operation of 8-axis CNC machines (Tsugami, Citizen). This role involves precision setup of complex, tight-tolerance parts, program verification, tooling configuration, and in-process inspections to ensure that production meets engineering specifications, quality standards, and delivery goals.

Requirements

High School Diploma or GED; technical certificate or AAS in Machining preferred.
Minimum 3–5 years of CNC machining experience (Tsugami, Citizen preferred).
Swiss Machining Expertise – Strong understanding of CNC processes, live tooling, and synchronized operations.
Blueprint Reading – Ability to read and interpret GD&T, microns-based tolerances, and complex part geometries.
Precision & Quality Focus – Demonstrated ability to maintain tight tolerances on small parts with attention to detail.
Problem Solving – Capable of quickly diagnosing setup, tooling, or machine issues and implementing effective solutions.
Documentation – Organized approach to capturing setup documentation for future use and traceability.
Safety & Awareness – Strong understanding of machine motion and pinch points.
ERP system experience preferred (JobBOSS or similar).

Nice To Haves

Experience working with medical, aerospace, or high-precision small parts manufacturing is a plus.
Familiarity with CAM program verification (Mastercam, Esprit, or similar) is a plus.

Responsibilities

Perform full set-ups on Swiss-style CNC machines for both new and repeat production jobs.
Interpret setup sheets, programs, and part prints to determine correct tooling, bar stock, collets/guide bushings, and sub-spindle usage.
Lead, mentor, and assist in troubleshooting with other Set-up Machinists.
Load, verify, and adjust programs (Fanuc, Mitsubishi, or other OEM-specific controls).
Confirm proper alignment, tooling clearance, spindle speeds, and feed rates for small diameter, high-precision components.
Execute First Article Inspections (FAI) using micrometers, comparators, and other high-precision measuring equipment.
Adjust tool offsets, spindle sync, and bar feeder parameters as necessary to maintain dimensional accuracy and surface finish.
Troubleshoot issues such as chip buildup, coolant flow, bar feeder jams, or tooling failures during setup and startup.
Record and document setup information, including photos, tool lists, and critical setup parameters for future repeatability.
Monitor and ensure bar feeder alignment, material feed, and cutting tool performance throughout setup.
Maintain cleanliness of the machine, bar feeder, chip conveyors, and surrounding work area.
Assist operators with startup and handoff to production; provide support during first-run validation.
Accurately enter job status and inspection results in ERP (e.g., JobBOSS).
Perform minor maintenance tasks and report larger machine issues to maintenance or supervisors.
Comply with all safety protocols and standard operating procedures.
Identify and recommend continuous improvement opportunities related to cycle time, tooling, and part quality.
