What kind of products need CNC processing?

When aluminum alloy workpieces are machined, there are many processes to choose from. For example, laser or CNC processing is used for baffle opening. However, the cost is a huge difference between the two.

• What is CNC

CNC (computer numerical control) is the abbreviation of computer numerical control, which is an automated machine tool controlled by a program. The control system can logically process programs specified by control codes or other symbolic instructions, decode them through a computer, so that the machine tool can perform the specified actions and process the blank into semi-finished finished parts through tool cutting.

• Application scope of CNC processing

So when? What kind of products will choose CNC processing?
Take a simple example: chassis panel thickness is generally more than 5 thick), in this case, laser cutting will no longer be used for processing. The reason is as follows: when the workpiece with such thickness is opened, a more obvious section will be left, and the internal grinding of this section is difficult to carry out. Therefore, it is more appropriate to use CNC processing directly for such products.

• What other parts are suitable for CNC machining?

    1.Special-shaped parts

Irregularly shaped parts usually have poor rigidity and require mixed processing of points, surfaces, lines, etc. It is very difficult to guarantee the deformation and accuracy of special-shaped parts, so it is difficult for ordinary machine tools to complete the processing. CNC processing is required.

    2.Disk, sleeve, plate parts

Shaft parts with distributed holes on the surface, keyways, radial holes and curved surfaces. Such parts cannot be processed by general machine tools. Curved parts need to be processed by CNC vertical machining centers, and parts with apertures need to be processed by CNC horizontal machining centers.

    3.Box parts

These parts usually have holes, cavities inside, and a certain ratio of length, width, and height. Most of them are used in automobiles, medical equipment, and aircraft manufacturing. These parts have relatively high requirements for processing, and usually go through milling, drilling, expansion, boring, reaming, countersinking, tapping, and other processes, almost all of which are done once. Ordinary machine tool processing takes a long time and cannot guarantee processing accuracy, so these parts are generally processed using CNC machining centers.
