What are the advantages and disadvantages of CNC processing of hand model (cnc machining)

With the development of manufacturing industry, many precision parts are now processed by CNC.So why is CNC machining so popular?Because CNC processing is not only convenient to operate, and the processing effect is good.

Advantages of CNC processing:
1.CNC can be automatically processed
CNC machining usually refers to the precise machining controlled by computer numbers.Therefore, it can be controlled by the program instructions of CNC machine tools, and the whole processing process is carried out automatically according to the program instructions.Machine tools are highly automated, greatly reducing the labor intensity of workers.
Currently, many CNC machines can run unattended for the entire processing cycle, freeing up the operator to do other tasks.This provides a number of side benefits for CNC users, including reduced operator fatigue, reduced errors due to human error, and consistent and predictable processing times per workpiece
2, CNC machining accuracy is high
The second advantage of CNC technology is the consistency and precision of the workpiece.The typical accuracy of today's CNC machine tools is two thousandths of an inch to four inches or 0.05 to 0.10 mm, with repeatability accuracy approaching 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 easily be produced with the same precision and consistency.Can realize mass production, product quality is easy to control.
3, CNC machining flexibility
Since these machines are run by computer programs, running different artifacts is as simple as loading different programs.This brings with it another benefit: a quick transition.Because these machines are easy to set up and run and can easily load programs, their setup time is very short.
4, CNC processing efficiency is high
CNC machining can carry out multi-coordinate linkage, can process complex zero point.When the shape and size of the part need to be changed, only need to change the numerical control program, saving production preparation time.
5. CNC machine tools are controlled by program instructions, and the whole process of processing is carried out automatically according to program instructions.
6, CNC machining program not only includes the process of parts, but also includes the necessary process parameters to complete the process, such as cutting amount, feed route, tool size number and the movement of the machine tool.
7, CNC machining efficiency is high, high machining accuracy, low labor intensity, strong adaptability to different workpieces.
The disadvantages of CNC machining center are:
1. Higher technical requirements for operators and machine maintenance personnel
2, but its processing route is not easy to control, can not be as intuitive as ordinary machine tools.
