With the development of the economy, factories are becoming more and more industrialized. Many factories have already used CNC machining for operations. CNC machining is a new machining technology. Its main task is to program the machining program, convert the original manual work into computer programming, and can automatically process any products and parts directly according to the program pre-programmed by the technicians. So what are the advantages and disadvantages of CNC machining? The following is the sharing of the editor of Paike Automation:
Advantages of CNC machining:
1. CNC can be automatically processed
CNC machining usually refers to precision machining controlled by computer numbers. Therefore, it can be controlled by 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 of the machine tool greatly reduces the labor intensity of the workers.
At present, many CNC machine tools can run unattended throughout the machining cycle, freeing up the operator to do other tasks. This brings some incidental benefits to CNC users, including reduced operator fatigue, reduced errors caused by human errors, and consistent and predictable machining time for each workpiece.
2. High CNC machining accuracy
The second biggest advantage of CNC technology is the consistency and accuracy of the workpiece. The typical accuracy of today's CNC machine tools has reached two to four thousandths of an inch or 0.05 to 0.10 mm, and the repeatability is close to or better than eight thousandths of an inch or 0.02 mm. This means that once the program is verified, it is easy to produce two, ten or a thousand identical parts with the same accuracy and consistency. Batch production can be achieved and product quality is easy to control.
3. Strong flexibility in CNC machining
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 changeover. Since these machines are very easy to set up and run, and programs can be loaded easily, their setup time is very short.
4. High CNC machining efficiency
CNC machining can perform multi-coordinate linkage and can process complex zero points. When the shape and size of the part 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 can even process some unobservable processing parts.
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 due to the use of the optimal cutting amount.
Disadvantages of CNC processing
1. The technical requirements for operators and machine maintenance personnel are high
2. The CNC processing route is not easy to control and is not as intuitive as ordinary machine tools.
3. The purchase cost of machine tools is expensive.
The above advantages and disadvantages of CNC processing are shared here. CNC processing can greatly reduce the number of tooling. Even if the parts with complex shapes are processed, complex tooling is not required. If you want to change the size or shape of the parts, you only need to change the processing program of the parts.
