With the development of the economy, many factories have used CNC machining for their operations. CNC machining is a new processing technology. Its main task is to program the processing program, transform the original manual work into computer programming, and directly and automatically process any products and parts according to the programs prepared by the technicians in advance. So, what are the advantages and disadvantages of CNC machining?
First, the advantages of CNC machining:
1. CNC automatic processing
CNC machining generally refers to precision machining controlled by a computer. 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 machine tool has a high degree of automation, which greatly reduces the labor intensity of workers.
Today, most CNC machining machines can operate unattended throughout the machining cycle, allowing operators to free up time for other tasks. This also has several benefits, including reduced operator fatigue, fewer errors caused by human error, and consistent and predictable machining times for each workpiece.
2. High accuracy of CNC machining
The second advantage of CNC technology is the consistency and accuracy of the workpiece. Today, typical accuracies for CNC machines are two to four thousandths of an inch or 0.05 to 0.10 millimeters. This means that once a program is proven, it is easy to produce two, ten or a thousand identical parts with the same precision and consistency. It can meet mass production, and the product quality is easy to control.
3. The flexibility of CNC machining
Because these machines are run by computer programs, running a different workpiece is as simple as loading a different program. This also brings the benefit of quick changeovers. Because these machines are so easy to set up and run, and programs can be loaded with ease, they take very little setup time.
4. The efficiency of CNC machining is high, and CNC machining can realize multi-coordinate linkage and complex zero point processing. When it is necessary to change the shape and size of the part, only the CNC program needs to be changed, which saves production preparation time.
5. It can process complex profiles that are difficult to process by traditional methods, and even process some unobservable processed parts.
6. In the case of many varieties and small batch production and processing, the production efficiency is higher, and the time for production preparation, machine tool adjustment and process inspection is effectively reduced, and the cutting time is reduced due to the use of the best cutting amount.
Second, the disadvantages of CNC machining
1. High technical requirements for operators and machine maintenance personnel
2. The CNC machining route is inconvenient to control, not as intuitive as ordinary machine tools.
3. The purchase of machine tool equipment is expensive.
The advantages and disadvantages of the above CNC machining are shared here. CNC machining can greatly reduce the number of molds. When machining complex parts, complex tools are not even required. If you want to change the size or shape of the part, you only need to change the machining program of the part.
