What Are The Advantages And Disadvantages Of CNC Machining?

With the development of economy, factories are becoming more and more industrialized. Many factories already operate using CNC machining. Numerical control machining is a new type of machining technology. Its main task is to write processing programs, the original manual work into computer programming, can be directly in accordance with the pre-written program of technical personnel automatic processing of any products and parts. So what are the advantages and disadvantages of CNC machining?

 

Advantages of CNC machining:

1, CNC can be automatically processed
CNC machining usually refers to precision machining that is digitally controlled by a computer. Therefore, it can be controlled by the program instructions of the CNC machine tool, and the entire processing process is automatically carried out according to the program instructions. The high degree of automation of the machine tool greatly reduces the labor intensity of the workers.
Currently, many CNC machines can run unattended throughout the machining cycle, freeing up the operator to perform other tasks. This brings a number of ancillary benefits to CNC users, including reduced operator fatigue, fewer errors caused by human error, and consistent and predictable machining times for each workpiece.

 

2. CNC machining precision is high
The second major advantage of CNC technology is the consistency and accuracy of the workpiece. The typical accuracy of today's CNC machines has reached two to four thousandths of an inch or 0.05 to 0.10 mm, with repeatability close to or better than eight thousandths of an inch or 0.02 mm. This means that once the program has been validated, two, ten, or a thousand identical parts can be easily produced with the same accuracy and consistency. Can achieve mass production, product quality is easy to control.

 

3. CNC machining flexibility
Since these machines are run by computer programs, running different workpieces is as simple as loading different programs. This also brings another benefit, namely fast conversion. Because these machines are so easy to set up and run, and programs can be easily loaded, their setup time is very short.

 

4. CNC machining efficiency is high
CNC machining can carry out multi-coordinate linkage and can process complex zero points. When the part shape and size need to be changed, only the CNC program needs to be changed, saving production preparation time.

 

5. It can process complex profiles that are difficult to process by conventional methods, and even process some machined parts that are not easy to observe.

 

6. In the case of multi-variety and small-batch production, the production efficiency is higher, which can reduce the time of production preparation, machine tool adjustment and process inspection, and reduce the cutting time by using the best cutting amount.
 

 

Disadvantages of CNC machining：

1. High technical requirements for operators and machine maintenance personnel.

 

2.CNC machining route is not easy to control, not as intuitive as ordinary machine tools.

 

3. The procurement cost of machine tools is expensive.

 

The advantages and disadvantages of the above CNC machining are shared here. CNC machining can greatly reduce the number of tooling. Even when processing parts with complex shapes, there is no need for complex tooling. If you want to change the size or shape of the part, just change the machining procedure of the part.
