What is CNC Turning? | Precision machining processing

 CNC Turning is the most basic and common cutting processing method, is an important job in the machinery manufacturing industry. Its work is in the lathe or CNC lathe, the use of workpiece rotation and tool linear or curved motion to change the shape and size of the blank, the workpiece will be processed into parts and components in line with the requirements of the drawings. 

Basic explanation of the turning process:

Turning machining process mainly includes the following steps: first, select the appropriate cutting tool; second, set the cutting parameters according to the workpiece material and processing requirements; then, clamp the workpiece on the lathe; then, start the cutting tool for rotary cutting; finally, through the adjustment of the cutting parameters and the lathe movement mode, to achieve the control of the precision and roughness of the surface of the workpiece. In the whole process, the use of cutting fluid is also very important, which can help reduce the cutting temperature, increase tool life and improve machining quality.

Specific example: Take the machining of a shaft part as an example, we need to analyse its structural characteristics, dimensions, post-processing requirements and machining difficulties. Due to the high surface roughness requirements of the part, we need to use high-speed steel tools for high-speed cutting. In practice, we first clamp the workpiece on the CNC lathe, and then set the appropriate cutting speed, feed and depth of cut. Next, start the CNC system, so that the lathe tool in accordance with the preset trajectory for rotary cutting. During the machining process, we need to constantly check the machining quality and accuracy of the workpiece, and if we find that it does not meet the requirements, we also need to constantly adjust the cutting parameters in order to maintain the balance of cutting quality and efficiency to ensure the machining quality. Finally, by analysing the machining results, we can conclude whether the dimensional accuracy and surface roughness of the part meet the design requirements.

The impact of turning machining on the industry:

As a traditional machining process, turning processing has been widely used in various fields in our factory. Automobile manufacturing is one of the main application areas of CNC Turning. Automotive manufacturing process requires a large number of shafts, discs, bushings and other rotating body parts, these parts usually need to be processed with high precision, CNC Turning can meet these needs, and can greatly improve production efficiency and product quality. The aerospace industry has very high requirements for accuracy and quality. For example, rotors and blades in aircraft engines require high-precision CNC turning. Machinery manufacturing is also an important application area of CNC Turning. All kinds of mechanical equipment need to be used in the rotating body parts, such as bearings, gears, screws and so on. The machining accuracy and quality of these parts directly affect the performance and life of mechanical equipment, so CNC Turning plays an important role in the machining of these parts. CNC Turning is also used in the manufacture of precision instruments. For example, optical instruments, measuring instruments, electronic instruments and so on need to carry out high-precision turning processing to ensure their performance and accuracy.

 With the continuous development of modern manufacturing technology, our engineers are constantly optimising and upgrading the turning process. For example, the application of CNC technology makes turning machining have a higher level of automation, stronger processing capability and wider adaptability; at the same time, The development of new cutting tools has also provided strong support for improving the efficiency and accuracy of turning processing and manufacturing precision parts. In addition, the concept of green manufacturing has also prompted us to carry out turning processing in the direction of more environmentally friendly, energy-saving development.
