Advantages of CNC machining:
1. CNC can be automatically processed.
CNC machining generally refers to computer-controlled machining, which can be controlled through program instructions of CNC machine tools. The entire machining process can be automatically carried out according to program instructions. The high degree of automation of machine tools greatly reduces the labor intensity of workers.
Currently, many CNC machine tools can be unmanned throughout the entire processing cycle, allowing operators to take time to complete other tasks. This brings some additional benefits to CNC users, including reducing operator fatigue. Reduce errors caused by human errors, and the processing time of each workpiece is predictable.
2. High CNC machining accuracy.
The second advantage of CNC technology is the consistency and accuracy of the workpiece. Nowadays, the typical accuracy of CNC machine tools has reached 2000-4 inches or 0.05-0.0 millimeters, and the repeated accuracy is close to or better than 8 inches or 0.02 millimeters. This means that once the program is validated, the accuracy and consistency of two identical components can be easily produced. Ten or a thousand identical parts. Can achieve large-scale production, and product quality is easy to control.
3. CNC machining has strong flexibility.
Since these machines are run by computer programs, running different workpieces is as simple as loading different programs.
This also brings another benefit, which is fast conversion. Due to the ease of setup and operation of these machines, as well as the ease of loading programs, the setup time is very short.
4. High efficiency of CNC machining.
CNC machining can perform multi coordinate linkage and handle complex zero points. When the shape and size of the parts need to be changed, only the CNC program needs to be changed to save production preparation time.
5. It can handle complex profiles that are difficult to handle with traditional methods, and even some unobservable processing parts.
In the case of multiple varieties and small batch production, due to the use of cutting quantity, production efficiency is high, which can reduce the time for production preparation, machine tool adjustment, and process inspection.
There are also some drawbacks to CNC machining.
1. The technical requirements for operators and machine maintenance personnel are high.
Compared with ordinary machine tools, CNC machining routes are not easy to control.
3. The cost of purchasing machine tool equipment is relatively high.
