CNC machining involves the application of computer-controlled cutting tools to blank workpieces to create new parts with automated speed and precision. From prototyping to full production runs, our CNC milling and turning processes use drills, end mills, and lathes to achieve complex geometries and angles, and are easily scalable for high volume manufacturing requirements.
Manufacturing CNC parts with Fast Radius is simple. Upload your CAD file to our Cloud Manufacturing Platform™ and then work with us to optimize your part and choose the right tooling, material, and finishing options. When your project is ready, we’ll manufacture your parts and deliver them to you.

Our CNC machining technologies
Our CNC machining capabilities include automated milling and turning services:
Milling
CNC mills are effective for geometric designs and rapid production requirements. Our CNC machining capabilities include both 3-axis and 5-axis mills.
Turning
CNC turning is a process in which an automated lathe shapes a rotating workpiece. Turning is useful for rounded or cylindrical geometries.
CNC machining applications
Cost-effective and fast to produce, CNC machined parts serve a spectrum of industrial applications:
Complex dimensions
Manufacture parts with complicated cuts and angles using precision cutting, drilling, and turning tools. CNC machining is ideal for creating parts with features located along or around axes, or with radial holes, grooves, and slots.
Niche manufacturing
CNC machining is capable of producing a range of niche or specialized metal and plastic parts, including oblong and cylindrical shapes, or complex parts that need to be cut from multiple axes.
Automotive and aerospace
CNC machining is ideal for creating high tolerance parts to exacting certification standards, for end-use in the automotive and aerospace industries.
Hybrid manufacturing
CNC machining is not just a process for metals: molded and 3D printed parts can also be machined for use in complex assemblies or hybrid manufacturing projects.
Why choose CNC machining for your parts?
Efficiency and repeatability
We can manufacture your CNC machining project with automated speed and efficiency, and repeat the process across batches of thousands of parts.
Consistent tolerances
Execute parts production with precision, holding exceptionally tight tolerances across high volume runs.
Scalability
CNC milling and turning processes can be scaled up quickly and cost-effectively to meet high volume production requirements and changing market demands.
Customization
Your CNC parts can be machined in a wide variety of metals and plastics, and then customized with finishing and post processing options to suit their end-uses.
