What Is CNC Turning & How Does It Work

CNC turning is a specific type of CNC machining process that involves material removal. During the CNC turning process, the workpieces are held in a chunk and rotated while the turning cutter is fed to the workpiece to cut materials away until the desired custom CNC turned parts are created.

Working on the same principle as a lathe, CNC turning adopts one of the most traditional forms of manufacturing. Assisted by computer numeric control (CNC), it promises high accuracy. In CNC turning, feed is measured in inch per revolution (ipr) or millimeters per revolution (mpr).

CNC turning is perfect for dealing with cylindrical shaped workpieces such as shaft, disk, and shaft sleeve (although it can also be used for square or hexagonal-shaped parts).

Benefits of Our Custom CNC Turning

CNC turning provides you with a fast and reliable solution to create your custom parts with tons of advantages, including the following:
  1. Higher Machining Precision.
CNC turning is numerically controlled by programs, therefore the CNC turned parts can achieve extremely high accuracy according to the design files without any human errors during the process. CNC turning also produces high surface quality that sometimes requires no post-processing.
  1. Cost-Effective.
CNC turning is a low-cost solution to produce parts and components in low or large volume. The savings mostly come from its fast production capability, which reduces the overall CNC turned part cost, and also the lablor and management cost. Remember to contact a reliable and experienced CNC turned part manufacturer so you can benefit from its advanced facilities at the most competitive price.
  1. Improved Efficiency.
CNC turning production can be scaled up very quickly as you demand. This type of precision machining can produce thousands of CNC turned parts fast with constant quality standard from the beginning to the end. That’s to say, you will find the last CNC turned part exactly the same as the first one in the production line.

1. What is a CNC turning machine?

CNC in full form is computer numerical control and therefore the CNC turning machine is operated by computer programs. Compared with the traditional lathe, the CNC turning machine can produce complex custom parts and components to precise specifications according to your design files.

2. What parts are ideal for CNC turning?

While capable of processing square and hexagonal-shaped materials, the CNC turning process is best for tubular and circular shaped raw materials, including the following:

  • Inner and outer cylindrical surfaces
  • Inner and outer conical surfaces
  • Grooves, threads & rotational molding surfaces

Modern CNC turning machines are capable of handling different tools, spindles, and speeds. With various cutting tools available, CNC turning machines can create different parts with complex geometries. Generally, CNC turning is popular for making parts with the following criteria:

  • Rotary parts with high precision requirement
  • Rotary parts with good surface roughness
  • Super precision parts with ultra low surface roughness
  • Rotary parts with complex surface shapes
  • Rotary parts with horizontal machining
  • Parts with some special types of threads

Overall, CNC turned parts are widely used in the field of machine manufacturing, aerospace, automobile part manufacturing, and service factories.

3. CNC turning and CNC milling, what's the difference?

CNC turning rotates the workpiece instead of the tool and it’s mainly used for irregular and flat surfaces. By contrast, CNC milling rotates the cutting tools against the workpieces, and this process is ideal for creating cylindrical or conical parts. Generally, CNC turning and milling are combined to make custom precision machining parts.

Yijin provides both CNC milling and turning services and will advise the best CNC milling or turning solution to manufacture your parts according to the design files and requirements.

4. How much does a CNC turning part cost?

The cost of your CNC turning parts varies depending on a lot of factors, including the complexity of your design (operations needed during the process), the materials (think about aluminum vs copper), the feature requirement, etc.

The best (and easiest) way to know the cost of your CNC turning part accurately is to send us a message with your drawings (in the format of stp, *.sldprt or igs for 3D/dwg, dxf, png, pdf or jpg for 2D) and quantity requirement. We will get back to you with detailed quotations and suggestions.

As a world-leading custom CNC turned parts manufacturer, Yijin always provides better CNC turning services and products at less cost.

5. What's the difference between CNC lathe and CNC center?

CNC turning is usually performed either on the CNC lathe or turning center. What is cnc turning center? Generally speaking, the CNC turning centers are more advanced than the CNC lathe with the capabilities of facing, threading, knurling, drilling, boring, reaming, milling and turning.

6. How many axis are there in CNC turning?
The CNC turning centers have 3, 4, or 5-axis types with more complex structures, higher production capabilities and versatility, while the CNC turning lathe machine is simpler with 2 axis.
