What are the differences between CNC machining and conventional machining?

Time : 2021-09-15 Hits : 30

NC machining and machining are the processing processes often used in hardware processing. NC processing technology comes from conventional processing technology. It belongs to the perfect combination of conventional processing technology and computer NC technology, computer-aided design and auxiliary manufacturing technology. Due to the continuous development of technology, there are more and more parts that need precision machining in modern manufacturing industry, The requirements for machining accuracy and the surface complexity of machined parts are becoming higher and higher. Therefore, NC machining is often widely used. However, from the perspective of cost, the cost of NC machining is higher than that of traditional machining process. Next, follow hongweisheng precision technology to see the differences between CNC machining and traditional machining process:

1.Differences in processing technology

  In the conventional machining process, it can be simplified in many aspects, such as positioning benchmark, clamping method, machining tool and cutting method, but the data processing process will be more complex, so these many factors need to be fully considered, and because the same machining task is used, There are many product solutions for NC machining process, which can make the main line arrangement for multiple machining filling and machining tools. The process has the characteristics of diversification, which is the difference between NC machining process and traditional machining process;     

2. Difference between clamping and fixture

  In the NC machining process, not only the coordinate direction of the fixture and the equipment should be relatively fixed, but also the dimensional relationship between the parts and the equipment coordinate system should be coordinated. In the clamping process, the two steps of positioning and clamping need to be effectively controlled. Under the conditions of traditional machining process, because the processing capacity of the equipment itself is relatively limited, Therefore, it is necessary to carry out multiple clamping in the machining process, and also need to use special fixtures, which leads to the high cost of fixture design and manufacturer, which virtually increases the production cost of products. However, the positioning of NC machining process can be debugged with instruments, and in many cases, there is no need to carry out special fixture design, so, Relatively speaking, its cost is lower;

3. The tool uses the above differences

   In the process of machining, the selection of cutting tools needs to be determined according to the difference between machining process and machining method. Especially in the process of NC machining, the use of high-speed cutting is not only conducive to the machining efficiency, but also the machining quality is more guaranteed, which can effectively reduce the probability of deformation caused by cutting and shorten the machining cycle. Therefore, In high-speed cutting, the demand for cutting tools is higher;

   At present, there is still a dry cutting method in the field of machining in the world. This cutting method cuts without cutting fluid or only needs a small amount of cutting fluid. Therefore, the tool needs to have excellent heat resistance. Compared with ordinary machining technology, NC machining technology has higher requirements for the performance of the tool;

   The above is the difference between CNC machining and conventional machining. I hope this article can help you.
