Machining of parts on a lathe. Abstract industrial background. Tinted in cold industrial colors.Computer numerical control (CNC) turning is one of the most commonly used manufacturing methods, with the ability to fabricate contoured cylindrical parts with exceptional accuracy and repeatability. Countless machines across industries rely on precision shafts and rods to operate. These shafts and rods typically get created using the turning process because of its ability to reliably create axisymmetric parts. In this blog post, we’ll go over the CNC turning process and the types of parts that the process can produce.

How Does CNC Turning Work? 

In CNC turning, a cutting tool moves linearly in conjunction with a rotating workpiece. A lathe rotates the workpiece at high speeds, while the cutting tool gradually reduces the workpiece’s diameter in accordance with the specified part design. The CNC process is performed until the workpiece reaches the designated dimensions and forms a completed part.

There are four types of CNC turning: taper turning, straight turning, external grooving, and profiling. Each of these processes can produce different shapes, including conical, straight, grooved, or curved workpieces. Regardless of the specific process, turning typically uses single-point cutting tools that achieve sets of angles that are unique to each workpiece material. Most CNC turning centers and lathes can also accommodate tooling for additional secondary processes, such as boring and drilling.

What Parts Can CNC Turning Make?

CNC turning services are highly versatile, which makes them ideal for industries ranging from engineering and aerospace to fine art. Typical parts made from CNC turning may include:

  • Metal components. Countless automotive, aerospace, and heavy machinery applications rely on turned metal shafts, rods, and other various components. Common metal materials used in these parts may include aluminum, brass, and steel.
  • Acrylic components. CNC turning is a popular method for creating cylindrical acrylic parts, such as components for signage, machine parts for microfluidic devices, and decorative items such as ornaments and art pieces. 
  • Electronic components. CNC turning is valuable for manufacturing various electronic components, including components used in printed circuit boards. Computer-controlled manufacturing processes have made these parts smaller and more efficient than ever before.
