How Much Do You Know about CNC Machining?

Nowadays, CNC machining has been widely used in many modern machinery productions. Then what is CNC machining? This article will take you to understand more knowledge of CNC machining.

What is CNC machining?

Generally speaking, CNC machining refers to precision machining, CNC machining lathe, CNC machining milling machine, CNC machining boring machine and milling machine etc. In fact, it is an automated machine tool equipped with a program control system. Numerical control machine tool is also called computer numerical control, which is an automatic machine tool controlled by a program. The advanced control system can logically process a program with control codes or other symbolic instructions, and decode it by a computer, so that the machine tool can operate and process parts. For example, the rough material is processed into semi-finished finished parts by cutting tools.

What is the history of CNC machining?

In fact, people began to use CNC machining technique in the 18th Century. The first 'turning the machine with a metal frame' was invented in 1751, which marked the industrialization began from that time. In 1952, Richard Kegg cooperated with MIT to develop the first CNC milling machine - the Cincinnati Milacron Hydrotel. After five years later, he applied the patent for a “Motor Controlled Apparatus for Positioning Machine Tool”, which means that this technology began to use for commercial function.

What are the advantages of CNC machining?

The control system can logically process the control codes and process the blanks into semi-finished parts through tool cutting. In actual applications, CNC molding technology can be used with metal materials to create the product with better accuracy and texture. The most representative products around us in the tablet market are the iPad series. But CNC molding technology is more expensive, due to the incredible accuracy and accuracy of up to 0.001mm, and each finished product is made by precision drilling. At present, CNC forming technology is also used in the production of precision parts in the aerospace and racing industries, which is why high-end flat products adopt this process.

CNC machining has the following advantages:

1. The number of tooling is greatly reduced, and complex tooling is not required for processing parts with complex shapes. If you want to change the shape and size of the part, you only need to modify the part processing program, which is suitable for new product development and modification.

2. The processing quality is stable, the processing accuracy is high, and the repeat accuracy is high, which is suitable for the processing requirements of aircraft.

3. The production efficiency is higher in the case of multi-variety and small batch production, which can reduce the time of production preparation, machine tool adjustment and process inspection, and reduce the cutting time due to the use of the best cutting amount.

4. High-quality CNC machining can process complex profiles that are difficult to process by conventional methods, and even process some unobservable processing parts. Of course, the disadvantage of CNC machining technology is that the cost of machine tool equipment is expensive and requires a high level of maintenance personnel.
