With the development of the economy, factories are becoming more and more industrialized, and many factories have already used CNC machining for operations. CNC machining is a new machining technology, whose main task is to program machining programs, converting original manual activities into computer programming. It can automatically process any product and component according to the program pre programmed by technical personnel. So what are the advantages and disadvantages of CNC machining?
a、 Advantages of CNC machining:
1. CNC can automatically process
CNC machining usually refers to precision machining controlled by computer numerical control. Therefore, it can be controlled through the program instructions of the CNC machine tool, and the entire machining process is automatically carried out according to the program instructions. The high degree of automation in machine tools greatly reduces the labor intensity of workers.
At present, many CNC machine tools can operate unattended throughout the entire machining cycle, allowing operators to free up time for other tasks. This brings some additional benefits to CNC users, including reducing operator fatigue, reducing human error propagation, reducing operator fatigue, reducing errors caused by human errors, and ensuring consistent and predictable processing times for each workpiece.
2. High CNC machining accuracy
The second major advantage of CNC technology is the consistency and accuracy of the workpiece. The typical accuracy of today's CNC machine tools has reached 0.2 to 4 inches or 0.05 to 0.10 millimeters, with repeat accuracy close to or better than 0.8 inches or 0.02 millimeters. This means that once the program is validated, it can easily produce two, ten, or a thousand identical parts with the same accuracy and consistency. It can achieve mass 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 ability to easily load programs, their setup time is not short
4. High CNC machining efficiency
CNC machining can perform multi coordinate linkage and can process complex
Miscellaneous zero point. When the shape and size of the parts need to be changed,
Simply changing the CNC program saves production preparation time
Between.
5. It can process complex materials that are difficult to process using conventional methods
Miscellaneous profiles can even be processed for some unobservable processing
Location.
6. In the case of multiple varieties and small batch production,
Higher production efficiency can reduce production preparation and machine tool adjustments
The time for process inspection is due to the use of the optimal cutting amount
And reduce cutting time.
b、 Disadvantages of CNC machining
1. Technical skills for operators and machine maintenance personnel
High requirements
2. The CNC machining route is not easy to control and is not as good as ordinary ones
Machine tools are intuitive.
3.The procurement cost of machine tool equipment is relatively high.
