A CNC Machinist is responsible for setting, operating, and maintaining computer numerical control (CNC) machines to produce precision-engineered components. Working across industries such as aerospace, automotive, manufacturing, and engineering, CNC Machinists play a critical role in producing high-quality parts to exact specifications. Using automated machinery such as CNC mills, lathes, and multi-axis machines, they ensure components are manufactured accurately, efficiently, and consistently.

​

Key responsibilities of a CNC Machinist typically include:

​

• Setting up and operating CNC machines to produce components to specification

• Reading and interpreting technical drawings, CAD models, and engineering plans

• Selecting appropriate tooling, materials, and machine settings

• Editing or adjusting CNC programmes where required (often using G-code)

• Inspecting finished components using measuring equipment such as micrometres and calipers

• Maintaining machinery and ensuring a clean and safe working environment

​

To succeed as a CNC Machinist, professionals need strong technical and practical skills, alongside a high level of attention to detail. The ability to read engineering drawings and understand tolerances is essential, as is experience working with different materials and machining processes. Knowledge of CNC programming, tooling, and machine maintenance is highly valued. Successful machinists are typically methodical, precise, and focused on producing high-quality work.

​

Career progression for CNC Machinists is well defined, with opportunities to move into roles such as CNC Programmer, Production Supervisor, Manufacturing Engineer, or Workshop Manager. Many professionals also specialise in advanced machining techniques, including multi-axis machining or high-precision components. Ongoing training and upskilling, particularly in CNC programming and CAD/CAM software, can support long-term career development.

​

Qualifications typically include an apprenticeship, NVQ, or diploma in Engineering or Manufacturing. Hands-on experience is highly valued, particularly within precision engineering or production environments. Additional training in CNC programming or specific machine types can further enhance employability and progression.
