What does a machinist do?
Machinists make precise parts by removing material from blocks, bars and sheets of metal, plastic or other materials. The parts they make go into engines, aircraft, medical implants, firearms, farm equipment and the machines that run factories. Many parts must be accurate to within a few thousandths of an inch or less.
A machinist’s work starts with a blueprint. They study the drawing, plan the order of operations and choose the right tools, speeds and feeds. Then they set up the machine, clamp the material in place and make the cuts.
Most shops today use CNC machines, which follow programmed instructions to cut parts. Machinists load programs, set tool offsets, run first parts and measure them carefully. If something is off, they adjust the program or setup. Many machinists also run manual lathes and mills for one-off parts and repairs.
Quality checks are part of every job. Machinists use precision measuring tools to make sure each part matches the drawing.
Good machinists are patient, careful and comfortable with numbers. You need to picture a finished part from a flat drawing, plan each cut in the right order, and catch small errors before they turn into scrapped parts. Many machinists also enjoy the problem solving that comes with tricky setups, tough materials and tight tolerances. Mechanical aptitude and good hand-eye coordination help, especially on manual machines.
Tools of the job include CNC mills and lathes, manual machines, grinders, drill presses, cutting tools, micrometers, calipers, height gauges, indicators and coordinate measuring machines (CMMs).
Machinists work in:
- Machine shops and job shops
- Aerospace and defense manufacturers
- Automotive and heavy equipment plants
- Medical device companies
- Maintenance departments in factories and power plants
A typical day
- Review blueprints and the day’s work orders
- Set up machines, tools and fixtures
- Run first parts and measure them carefully
- Adjust offsets or programs and run production
- Inspect, deburr and document finished parts
Machinist pay and job outlook
According to the U.S. Bureau of Labor Statistics, machinists earn a median of $58,750 a year, or $28.24 an hour. Programmers, setup machinists and those in aerospace or medical work often earn more. Overtime is common in busy shops.
The BLS counts about 288,300 machinist jobs. Employment is projected to grow 1% from 2025 to 2035, which is slow. Still, there are about 26,100 openings a year, mostly from workers retiring or changing careers.
Pros
- Solid pay without a four-year degree.
- Paid apprenticeships and employer training are available.
- Skilled, precise work with clear results.
- Paths into programming, engineering support and management.
Cons
- Slow overall job growth.
- Shops can be loud, and you stand for most of the shift.
- Mistakes can be costly, so the work can be stressful.
- Some jobs require night or weekend shifts.
Training options: school vs. apprenticeship
Machining program. Community colleges and trade schools offer certificates and associate degrees in machining or CNC technology. Certificates may take about a year, and associate degrees about two. Costs typically range from a few thousand dollars at many community colleges to more at private schools. Look for programs with plenty of machine time and modern CNC equipment.
Apprenticeship. Registered machinist and tool and die apprenticeships usually take about four years. You work full time in a shop for pay while taking related classes, often at a community college. Wages rise as you progress. Some manufacturers run their own apprenticeship programs.
On-the-job training. Many shops hire CNC operators with little experience and train them. If you are motivated, you can learn setup and programming over time. Taking evening classes can speed things up.
Certification and licensing by state
Machinists do not need a state license. Employers hire based on skills, experience and credentials.
NIMS credentials are the best-known industry certifications. They are based on national skill standards and include hands-on performance tasks plus written tests. Many machining programs prepare students for them.
A completed registered apprenticeship is another strong credential. Some employers also value CAM software certifications or training in quality systems and inspection.
Specializations and where they lead
- CNC programmer. Write and edit programs using G-code and CAM software. Often pays more than machine operation.
- Tool and die maker. Build the tools, dies, molds and fixtures used in manufacturing. Usually requires years of experience or an apprenticeship.
- Quality inspector. Use CMMs and precision tools to check parts and keep processes in control.
- Setup machinist. Prepare and prove out machines and programs for production runs.
- Shop lead or manufacturing engineer. Experienced machinists can lead shops or, with more education, move into engineering roles.
How to choose a machining school
The right program gets you plenty of machine time and helps you get hired. Ask these questions:
- How many hours will I spend on machines? Ask for the split between shop and classroom time.
- What equipment does the shop have? Look for modern CNC mills and lathes, plus manual machines.
- Does the program teach CNC programming and CAM software? These skills can boost your pay.
- Are NIMS credentials part of the program? Ask how many students earn them.
- Is the school accredited, and is it eligible for federal financial aid (FAFSA)? Ask about the total cost, including tools.
- Does the school partner with local manufacturers or apprenticeships? These ties can lead to jobs.
- What job placement help do you offer? Ask which shops hire graduates.
