The History Of CNC Turning

The history of CNC turning is really vast! In the era of computer-controlled precision, history takes us on a journey from manual craftsmanship. So, it all started with manual lathes. Skilled artisans would use their hands to turn raw materials into these intricate components.
The journey of CNC machining started in the mid-20th century. A turning point came when punched cards were used to automate NC control machining. Wow, this really made a big difference in terms of accuracy and efficiency! But CNC turning went through quite a transformation in the 1940s and 1950s thanks to computer integration.

Do you know who played a key role in advancing the first CNC lathe? FYI, a CNC lathe is a primary type of CNC turning machine. He was John T. Parsons. It was a technological breakthrough that really set the stage for computer-controlled automation. However, in the 1976s, people started using microprocessors. These little chips made it possible to control things in real time and do more complicated tasks.
CNC turning is becoming a more advanced field these days. Multi-axis capability, fast spindles, and sophisticated software power it. Precision has significantly improved as a result of this change. Indeed, they also managed to cut down on production times and broaden the variety of materials they could work with.

Types Of CNC Turning Machines

The laser market offers different types of CNC turning machines. Nonetheless, we can identify two major types of them when we use various co-ordinate systems. They are generally horizontal and vertical turning machines.
In addition, in terms of CNC turning machines, your choice is also dictated by what you require for your CNC turning parts project. In such a case, the size and complexity of the CNC turning parts will be one of the considerations you would make for the project you are planning. You might need some tolerance to be included in your project. However, it will also depend on the particular applications that you intend to use it.

Horizontal Turning Centres

Horizontal Turning Centres have a horizontal spindle configuration. It means that the spindle can rotate workpieces horizontally. These machines are really famous for being super adaptable and able to handle all sorts of turning operations.

Vertical Turning Centres

Vertical turning centers are specially made for turning or machining heavy & cylindrical workpieces. So, the main thing that sets a vertical turning center apart is it’s vertically oriented spindle. Basically, it lets you clamp the workpiece vertically and have the cutting tool come in from above. This setup works well for turning & machining tasks involving large components with varying diameters.

CNC Turning Parts Manufacturer Processing

The manufacturing of making CNC turning parts is a systematic process. Well, the CNC turning machining process involves a precise series of steps. These steps transform raw materials into intricate and precise CNC turning parts. First, the process begins with the careful selection of the raw materials. Here, note the material considerations. Usually, we choose metals for most of these operations. And then, we securely mount this material onto the CNC lathe.

The next step is tool selection. This step is very important because it involves choosing appropriate cutting tools. You know, inappropriate cutting tools may create hazardous situations. So, the tool selection is very important. However, the tools may include inserts, drills, and others.

Here comes the next step. Well, computer programming is the most crucial step at this moment. Either you can type or insert CNC programming into the machine’s control system. After pushing the start button, the machine automatically processes and cuts the material. In the end, the process makes the raw material into the desired form.

In addition, the process carries out some quality inspection works. Why is it necessary? This is because it shows that the dimensions & surface finish comply with recommended standards. However, for this measurement, calipers, micrometers, or gauges are applied. To achieve more refined accuracy, the last step is finishing. One can mention, for instance, polishing, grinding, or other finishing treatment techniques.

Quality Control Measures Used In The CNC Turning Process

Why should we have quality control programs in place? Why in CNC turning? It forms an integral part of the CNC turning process. It also guarantees that the turning components are within the specified limits. The following three are key quality control measures used in CNC turning:

ISO 9001

ISO 9001 is an internationally recognized quality management standard. Consequently, many CNC turning parts suppliers follow this standard. It highlights that they are committed to maintaining a high level of accuracy. In addition, it provides structured quality management.
Moreover, it encompasses documentation, training, continuous improvement, and customer satisfaction. Overall, ISO 9001 signifies a rigorous quality management system.

Quality Inspection

Quality Inspection is another crucial production step for every CNC turning parts manufacturer. It is an ongoing process during CNC turning. Quality inspection involves systematic checks & verifications at different production stages. Skilled operators & quality control personnel use various measuring tools & techniques. Inspection tools include calipers, micrometers, coordinate measuring machines (CMMs), and optical comparators. These instruments assess the quality of dimensions, surface finish, and overall CNC turningparts.

Quality Control

Finally, a quality control system involves appropriate process control. It may include monitoring the CNC turning process. The monitoring identifies & rectifies any deviations that may affect the quality of CNC turning parts. In addition, quality control measures maintain proper machine conditions and tool wear monitoring. According to optimal control measures, monitoring feedback loops adjust machining parameters as needed. Overall, control focuses on minimizing variability and maintaining product quality throughout production.
