CNC Turning may not be a term that many people are familiar with. However, it is likely that they have used or are familiar with something manufactured using the turning process.

So today we are going to take a look at what it is what is made using the CNC turning process.

Long before the use of precision engineering materials such as metal were manufactured into parts using manual methods and with the constant supervision of an experienced operator. As we all know; to err is human, and errors were common and showed up in the form of inaccurate measurements and inferior quality.

We live in a world of manufacturing where advancements in computer technology, together with experienced operators allows for parts to be manufactured to the highest specifications. CNC Turning is one of the most important machining processes and has helped to create the modern world.

History of CNC Turning

The CNC Turning process is based on one of the oldest machining tools, the Lathe. It should come as no surprise that the lathe made its first appearance in Ancient Egypt, in fact right back to 1300BC.

There were incremental improvements over the millennia until we reach the late 1940s. John T Parsons was working with the Massachusetts Institute of Technology. He was tasked by the US Air Force with finding a more cost-effective way to manufacture complex parts for aircraft. And being as the world was in the midst of WW2 it was imperative that the work was done fast.

Parsons created the process of Numerical Control (NC). Using punch cards to control tools to achieve something at speed, which would take even experienced machinist days to produce. The war effort required a process that could be used by new operators. Soon NC became the norm in the manufacturing industry.

In 1967 an improvement to the process came into being. Computer-controlled machining. By 1976 the first computer-aided 3D machining was introduced and within 13 years Computer Numerical Control (CNC) had become the industry standard.

What is the CNC Turning Process?

The process of CNC turning involves securing the raw material within the jaws of a lathe, the material is turned within the lathe and a single point cutting tool is moved parallel to the axis of rotation. This is the basic process of shaping the material. The measurements of the finished part are fed into the machine via CAD software.

Once the instructions have been read the computer controls the lathe to ensure that the parts are produced to the exact specifications. In conventional machining, the work is stationary while it is the tool that moves. Obviously, due to the nature of the process, the final part to be produced is cylindrical or oblong in shape.

Another benefit of the process is that unlike CNC Milling, which is another important process, which you can read about here, it offers us the ability to produce multiples of the same component, quickly and from a single piece of material.

Types of CNC Turning Lathes

The turning process uses many different types of lathe. Each type is suited to different processes.

Even though there are many, many types of lathe, the precision metal machining industry uses 4 common types.

Vertical CNC Lathe

Vertical lathes orient the spindle in a fixed position in the vertical plane. The workpiece moves up or down to place it in line with the appropriate tool necessary for the desired operation.

Vertical lathes are less complex than horizontal machines. They provide the best option for projects that focus on a single side, like large metal plates and sinking dies. They hold an advantage over horizontal lathes in circumstances where workpiece sagging might be a factor.

Horizontal CNC Lathes

Unlike vertical lathes, horizontal lathes do not have a fixed spindle but instead, they use a variety of heads mounted to a horizontal arbor. These machines accommodate a wider variety of shapes and sizes and gravity works to keeping the workpiece clean during machining. Most horizontal lathes have the capacity to incorporate automatic bar-stock feeders.

Horizontal Turning Centres

Horizontal Turning Centers are the most widely recognized CNC Machine here in Canada used by Parts Manufacturers for the Oil and Gas sector. With a horizontal turning center, the spindle is horizontally oriented, and tools are mounted out of the side of the tool holder and cut across the work-piece.

Horizontal Turning Centres

A vertical turning center is a cross hybrid from the turning center and the vertical lathe. Shorter components not requiring sub-spindle, tailstock, or bottom turret can benefit from a vertical construction lathe rather than a horizontal to keep the machine footprint small.

Advantages of CNC Turning

When compared with manual turning, there are multiple reasons why manufacturers prefer to use computer-aided technology. Not only is it more cost-effective, but it also allows for increased production speed and efficiency – meaning you can produce a lot more components in a shorter space of time.

Because of the increased level of precision that CNC Turning provides, manufacturers also see a reduction in waste as they can make more out of their raw materials. As well as these advantages, the following universal advantages also apply:

Speed

A CNC lathe can manufacture components at a very high rate, this is especially true for sliding stock lathes which can engage the stock with multiple tools at once. Some lathes even have multiple primary spindles that can engage up to six stock pieces with multiple tools. Not even the most advanced CNC mills can match the speed with which a sliding stock lathe can churn out parts.

Versatility

CNC lathes can come in multiple different configurations that can match any requirement from pure OD and ID turning to combinations of turning, off-axis drilling and even milling all in one machine. This results in the capability to run ‘done-in-one’ operations with ease.

Efficiency

A CNC lathe can operate non stop due to automatic material loading bar feeders. This means that the operator only needs to make sure the machine is continuously fed with the material, and it will continue to machine parts.

Which Industries can make use of CNC Turning?

CNC Turning is an extremely versatile manufacturing process. While it is mostly associated with the automotive, aerospace, and engineering industries, it can also be used to create objects like pieces of art and ornaments.
