1. The difference in processing technology
In the conventional mechanical processing technology, many aspects such as the positioning reference, the clamping method, the processing tool and the cutting method can be simplified, but the data processing technology will be more complicated, and it is necessary to fully understand these many factors. In addition, due to the use of the same processing task, the CNC machining process can have many product solutions, and can make a main line for multiple processing complements and processing tools to arrange the process. The process has diversified characteristics. It is the difference between CNC machining technology and traditional machining technology;
2. The difference between clamping and fixture
In the CNC machining process, it is not only necessary to keep the coordinate direction of the fixture and the equipment relatively fixed, but also to coordinate the size relationship between the parts and the equipment coordinate system. Steps are effectively controlled. Under the traditional machining process conditions, because the processing capacity of the equipment itself is relatively limited, it is necessary to carry out multiple clamping during the processing process, and also need to use special fixtures, which leads to fixtures in The cost of design and manufacturer is relatively high, which invisibly increases the production cost of the product. However, the positioning of the CNC machining process can be debugged using instruments. In many cases, it is not necessary to design special fixtures. Therefore, relatively speaking, its cost the lower;
3. The difference in the use of tools
In the process of processing, the choice of cutting tools needs to be determined according to the difference between the processing technology and the processing method. Especially in the process of CNC processing, the use of high-speed cutting is not only beneficial to the efficiency of processing, but also the quality of processing is more guaranteed. Effectively reduce the probability of deformation caused by cutting and shorten the processing cycle, so the demand for cutting tools is higher under high-speed cutting;
At present, there is still a dry cutting method in the field of mechanical processing in the world. This cutting method cuts without adding cutting fluid or only requires a small amount of cutting fluid. Therefore, the tool needs to have excellent heat resistance. Compared with ordinary mechanical processing technology, CNC processing technology has higher requirements for the performance of cutting tools.
