How to Become a CNC Machinist

If you love working with your hands, enjoy precision design, or take satisfaction in turning raw materials into finished parts, a career as a CNC machinist could be the perfect fit. 

Whether you're already using a desktop CNC machine at home or just exploring the possibilities, this guide will show you how to take your skills to the next level.

We’ll cover what CNC machinists do, how to get the right training, which tools and machines you'll use, and what kind of salary and work schedule to expect.

You'll also learn the difference between CNC machinists and CNC operators, and what it takes to turn your hobby into a rewarding, hands-on career.

What is a CNC Machinist?

A CNC machinist is a skilled professional who operates automated machines to cut, shape, and finish materials like metal, wood, and plastic. These machines follow precise instructions generated from CAD or CAM software, allowing for highly accurate, repeatable production. 

CNC machinists are essential in industries like aerospace, automotive, manufacturing, and even creative fields such as woodworking. Their role requires a mix of technical know-how, problem-solving, and hands-on skill to ensure quality and precision in every piece they produce.

Depending on the industry, CNC machinists may specialise over time. In aerospace and automotive, for example, machinists can move into precision component manufacturing or CNC programming roles. 

In manufacturing, there are opportunities to progress into quality assurance or production management. In creative fields like woodworking or prototyping, experienced machinists often transition into custom design, product development, or even run their own fabrication businesses. 

Each path offers room for growth, depending on your interests and skill set.

CNC Machinist Responsibilities

A CNC machinist performs a variety of technical and operational tasks to ensure that parts are produced accurately, efficiently, and to exact specifications. 

These responsibilities include:

• Reading and interpreting blueprints or CAD designs

• Setting up and calibrating CNC machines

• Selecting appropriate tools and materials

• Monitoring production and making adjustments as needed

• Performing quality checks on finished parts

• Routine maintenance of equipment

Is CNC Machining a Good Career?

CNC machinists are in steady demand across the US due to a growing need for precision manufacturing. As industries increasingly rely on automated machining, skilled operators are highly valued.

California is a state in high demand where aerospace and tech manufacturing drive job opportunities, and Texas, which benefits from growth in oil & gas, automotive, and aerospace sectors. 

Michigan remains a hub for automotive manufacturing, while states like Ohio, Indiana, and Illinois have strong machining and tooling industries.

Steps to Becoming a CNC Machinist

Start with Your Passion

If you're already using a hobby CNC like Onefinity at home, you’re ahead of the game. Experiment with projects, explore VCarve or Fusion 360, and build confidence with real-world applications.

Take a Course & Build a Portfolio

Enrol in a structured CNC machinist training program either online, through a technical school, or a hybrid model. 

Document your CNC projects with photos, videos, and process notes. A strong portfolio can help you stand out when applying for apprenticeships or entry-level positions.

Apply for an Apprenticeship or Entry-Level Role

Gain hands-on industry experience by starting in an assistant role or internship. Apprenticeships often combine practical experience with formal education.

Earn Certifications

Obtain industry-recognised certifications like NIMS (National Institute for Metalworking Skills) or OSHA safety training. These credentials show employers you’re serious and qualified.

Keep Learning and Specialise

As you gain experience, consider specialising in areas like CNC programming, quality control, or CAD/CAM design. Continuous learning will help you advance and increase your earning potential.

How Long Does It Take to Become a CNC Machinist?

Generally speaking, most training programs can be completed in 6 months to 2 years. This depends on the depth of study and the type of training you choose. 

For example, online courses can be part-time if you’re balancing other commitments. Whereas, apprenticeships often last 3 to 4 years but offer hands-on experience from day one.

Some hobbyists begin by learning at home using  CNC machines, gradually building up the skills to start their own side hustle to make money. 

It’s common to continue learning on the job, gaining experience with different machines, materials, and processes. 

This continuous learning helps pave the way for advancement into more specialised or higher-paying roles.

How Long Do CNC Machinists Work?

Full time CNC machinists typically work full-time shifts, often 40 hours per week. Depending on the employer and industry, this might include day, evening or overnight shifts.

The work can be physically active, involving standing for long periods and handling materials, but many machinists enjoy the variety and rhythm of shop life.

What is a CNC Machinist Salary?

The average salary for a CNC machinist in the US is around $48,000 to $60,000 per year, depending on experience, location, and industry. CNC machinists at every level may start around $40,000, while experienced machinists or those in specialised sectors can earn upwards of $70,000.

What Is The Difference Between A CNC Operator And A CNC Machinist?

Primarily, CNC Operators load materials, monitor machine output, and perform basic maintenance. Whereas, CNC Machinists do all of that plus interpret complex blueprints, adjust programming, and ensure precision.CNC machinists tend to have more training and handle a broader range of responsibilities.

Conclusion

Becoming a CNC machinist is more accessible than ever, especially if you’re already exploring the world of CNC as a hobby. With training  and a love of making things, you can turn your skills into a fulfilling and well-paying career.
