CNC Machinist – 1st Shift

This full-time CNC Machinist role is a 1st shift position, working Monday through Friday from 6:00 a.m. to 4:00 p.m. (approximately 50 hours per week) with optional weekend overtime. You will operate and oversee up to three CNC machines at a time in a high-volume, high-precision production environment, performing tool changes, loading programs, making minor program edits, and conducting regular quality checks on small steel parts produced to extremely tight tolerances.

Responsibilities
  • Attend daily shift meetings to review production priorities, assigned workstations, and machine schedules.
  • Set up and operate up to three CNC machines simultaneously, including mills, lathes, screw machines, grinders, Hydromat, or rotary transfer equipment, depending on experience and department assignment.
  • Perform frequent tool changes, completing up to 8–9 tool changes per day across assigned machines to support continuous production.
  • Load parts and material into the CNC machines and ensure correct fixturing, tooling, and offsets for each job.
  • Pull existing CNC programs for each job and make minor edits as needed to maintain part quality and meet specifications.
  • Monitor machines during operation to identify and resolve issues such as tool wear, dimensional drift, or alarms, minimizing downtime.
  • Read and interpret blueprints to understand dimensions, tolerances, and critical features for each part produced.
  • Perform regular in-process quality inspections using micrometers and calipers, typically every 300–400 parts, to verify parts meet tight tolerance requirements of approximately (+/-) 10–20 microns.
  • Document inspection results as required and take corrective action when parts approach or exceed tolerance limits.
  • Handle and organize finished parts, placing them into appropriate bins and preparing them for shipment to customers.
  • Work with different types and thicknesses of steel, adjusting machine parameters and tooling as needed for material variations.
  • Maintain a clean and organized workstation, including machines, tools, and measurement equipment.
  • Communicate effectively with team members and leadership about production status, quality concerns, and equipment issues.
  • Follow all safety procedures and guidelines while working in a loud, high-volume production environment.
Essential Skills
  • At least 5 years of hands-on experience operating CNC machines such as screw machines, CNC mills, or CNC lathes.
  • Minimum of 5 years of experience reading and interpreting blueprints to manufacture precision components.
  • At least 5 years of experience making edits to existing CNC programs to maintain part quality and meet specifications.
  • Proficiency with CNC machining operations in a high-volume, high-precision environment.
  • Ability to perform frequent tool changes and changeovers efficiently across multiple machines.
  • Strong blueprint reading skills, including understanding dimensions, tolerances, and geometric features.
  • Experience using precision measuring tools such as micrometers and calipers for in-process quality checks.
  • Ability to hold tight tolerances in the range of approximately (+/-) 10–20 microns on small steel parts.
  • Comfort working with multiple CNC machine types, including mills, lathes, screw machines, grinders, Hydromat, or rotary transfer machines.
  • Troubleshooting skills to identify and correct machining issues related to tooling, programs, or setup.
  • Capability to manage and prioritize work across up to three CNC machines at once.
  • Ability to work 1st shift (Mon–Fri, 6:00 a.m.–4:00 p.m.) and handle 50-hour work weeks.

Skills & Qualifications
  • Experience with CNC programming beyond minor program edits is a plus.
  • Background operating high-volume production equipment such as screw machines (e.g., Tornos), , centerless grinders, CNC mills, and CNC lathes is beneficial.
  • Familiarity with machining components for applications such as automotive, powertrain, or industrial equipment is advantageous.
  • Ability to adapt to different departments and machine types with training.
  • Strong attention to detail and commitment to producing high-quality, precision parts.
  • Good communication skills and willingness to participate in…
