First, the advantages of CNC machining:
1, CNC automatic machining
CNC machining usually refers to precision machining digitally controlled by a computer. Therefore, it can be controlled by the program instructions of CNC machine tools, and the whole process is automatically carried out according to the program instructions. Machine tool automation high degree, greatly reduce the labor intensity of workers.
Currently, many CNC machines can run unattended throughout the machining cycle, freeing up the operator for other tasks. This provides CNC users with several side benefits, including reduced operator fatigue, reduced errors due to human error, and consistent and predictable machining times per piece.
2, CNC machining precision is high
The second major advantage of CNC technology is the consistency and accuracy of the workpiece. Typical accuracy of today's CNC machines has reached two thousandths to four inches or 0.05 to 0.10 millimeters, with repeatability near or better than eight thousandths of an inch or 0.02 millimeters. This means that once the procedure has been validated, two, ten or a thousand identical parts can easily be produced with the same accuracy 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 also provides another benefit, which is fast conversion. Since these machines are very easy to set up and run, and programs can be loaded easily, their setup time is very short.
4, CNC machining efficiency is high
CNC machining can be multi - coordinate linkage, can process complex zero point. When the shape and size of the part needs to be changed, only the numerical control program needs to be changed, saving production preparation time.
5. It can process complex profiles that are difficult to be processed by conventional methods, and even process some unobservable machining parts.
6, in the case of multiple varieties, small batch production, production efficiency is higher, can reduce the production preparation, machine adjustment and process inspection time, due to the use of the best cutting amount and reduce the cutting time.
Second, CNC machining shortcomings
1. High technical requirements for operators and machine maintenance personnel
2. CNC machining route is not easy to control, as intuitive as ordinary machine tools.
3. The procurement cost of machine tools and equipment is expensive.
The advantages and disadvantages of CNC machining above are shared here. CNC machining can greatly reduce the number of tooling, even if the machining of complex parts does not need complex tooling. If you want to change the size or shape of parts, you only need to change the machining program of parts.
