CNC technology has fast become a leader in the precision machining industry. Using such technology allows for greater control, more accurate results, and a reduced need for manual labour during the manufacturing process. Here at PT Engineers, we are one of the country’s leading providers of CNC machining services, such as CNC turning and Milling. With our fully equipped suite of CNC machines, our company carries a wealth of CNC capabilities. As a result, we’re proud to have worked with many different companies over the years supporting them with their manufacturing requirements.

CNC Turning And CNC Milling 

When it comes to CNC turning and CNC milling, both processes harness the power and accuracy of cutting-edge automation technology. However, although both types of CNC machining share similarities, equally they offer different benefits and are ideal for different applications.

What Is CNC Turning? 

The CNC turning process involves the workpiece rotating against a cutting tool. This removes the material in whatever way is needed to produce the desired shape. For cylindrical components, a round bar stock is often in use with the method.

CNC Milling 

So how does CNC milling work? In the case of CNC milling, the workpiece is held in a stationary position. The tool that cuts the material spins against it in order to remove excess material.

What Do They Have In Common?

There are many similarities between CNC turning and milling, alongside the fact they rely on the same technology to deliver the highest levels of precision and production speed.

Subtractive Engineering

CNC turning and milling both work by carefully removing the material from the workpiece. Both will generate chips of the excess material as the workpiece is machined specifically to the desired profile or length.

Suitability For Materials

CNC milling and turning services are ideal for a wide range of materials including:

  • Aluminium
  • Brass
  • Copper
  • Steel
  • Titanium
  • Thermoplastics

If the material is too soft or too brittle it can be incredibly difficult to machine.

Heat Generation

Both turning and milling generate heat during their machining process. Therefore, cooling fluid needs to be in use in order to mitigate the head and prevent warping.

The Benefits

Both CNC turning and CNC machining can offer a range of cost and speed advantages.

Accurate Machining 

The ability to produce components to highly intricate specifications with tight tolerances.

Fast Production

The cutting operations for both types of CNC machining are performed very quickly. As a result, more parts can be produced which makes them suitable for both small and large batch requirements.

Less Room For Error 

A core benefit for any CNC machining process is the decreased risk of error. As the processes are guided by a computer, the cutting is incredibly precise. In addition, even complex parts can be made quickly without the risk of human error occurring.

Cost Effective Manufacturing 

Due to the speed of CNC milling and CNC turning, alongside the minimal manual labour involved, the processes are much more cost-efficient than other manufacturing processes such as 3D printing.

Which One Should You Choose? 

When it comes to determining which CNC machining service to go for, the application is what is going to be the deciding factor. The decision to go for turning or milling largely depends on the shape of the part you would like to manufacture, and the features it requires. For instance, whilst CNC milling is most appropriate for square, rectangular, and flat components, CNC turning is ideal for cylindrical components.
