Job description

A day in the life

It’s the start of your shift at Hirsh Precision. You pull up the next work order, load a program on a Mazak lathe, select the ideal insert, and dial in your offsets. A first-article passes inspection—micrometers, indicators, and height gauge confirm you’ve nailed the GD&T callouts. While that lot runs, you set up a Swiss lathe for the next job, balancing tool life, cycle time, and finish. Midday, you’re the go-to resource for an apprentice who’s learning setup strategy. Later, you chase down a stubborn tolerance, adjust feeds and speeds, and document the improvement so it sticks. Before you clock out, you record production data, confirm machine utilization is strong, and hand off cleanly to the next operator.

Role overview

The Precision CNC Turning Specialist II independently sets up, operates, and troubleshoots CNC and Swiss lathes to manufacture tight-tolerance components that meet engineering and customer specs. You’ll drive efficiency, quality, and continuous improvement while mentoring entry-level machinists and apprentices. This role builds toward CNC Lathe Machinist III, Lead Machinist, Programmer, or Supervisor roles based on mastery, leadership, and consistent results.

Openings are available on First and Second shift.

What you’ll handle

• Independently set up and run CNC and Swiss lathes
• Load, verify, and edit programs; perform tool and work offsets; validate first-piece quality
• Select, install, and manage tooling, fixtures, and workholding for throughput and repeatability
• Run multiple machines/operations as demand requires
• Track cycle times, machine performance, and job progress to hit schedule
• Accurately log setup, downtime, and production data

Quality & inspection

• Interpret complex blueprints with GD&T and tight tolerances
• Use advanced metrology: micrometers, indicators, bore/height gauges, CMM, and related tools
• Verify parts throughout the run to ensure first-pass yield
• Minimize scrap and rework through process control and attention to detail
• Escalate nonconformances and support corrective actions

Troubleshooting & improvement

• Diagnose issues tied to tooling, feeds/speeds, setups, fixturing, and machine capability
• Tune processes to reduce downtime, improve cycle time, and enhance part qualityRecommend better tooling strategies, setups, and workflows
• Engage in lean and continuous improvement initiatives

What you bring

• 3+ years of machining/CNC experience or equivalent demonstrated skill
• Proven ability to independently set up and operate CNC equipment
• Strong blueprint reading with GD&T fluency

• Education: High school diploma or GED (preferred)

Bonus points

• Experience with 4-axis and 5-axis machining centers
• CAM or program editing background
• High-mix, tight-tolerance manufacturing experience
• Vocational/technical machining training

Physical demands

• Stand for extended periods
• Lift up to 50 lbs occasionally
• Frequent bending, reaching, and repetitive hand motions
• Work safely around noise, coolant, and moving machinery

How success is measured

• Attendance: 98% or higher
• Daily production goal attainment: 90% or higher
• Scrap: 2% or less
• Setup times: meet or beat standards
• High machine utilization with minimal avoidable downtime
• Consistent in-spec parts with minimal rework
• Visible leadership, mentoring, and technical problem-solving
