CNC machining technology is derived from conventional processing technology and is an organic combination of conventional processing technology, computer numerical control 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, and the requirements for machining accuracy and surface complexity of the workpiece is also getting higher and higher. Therefore, CNC machining has received widespread attention, but in terms of cost savings, CNC machining is still more expensive than traditional machining. Below we will specifically introduce the advantages of CNC machine tools over conventional machining:
1. Processing technology
In the ordinary machining process, the positioning datum, clamping method, tool, cutting method and so on can be simplified during the process, but the data processing process is complicated, and these factors need to be fully considered. But the CNC machining process can have multiple solutions, which can arrange multiple machining parts and machining tools as the main line. The process has diversified characteristics. This is one of the advantages of CNC over conventional machining.
2. Clamping and fixture
In the CNC machining process, not only the coordinate directions of the fixture and the machine tool must be relatively fixed, but also the dimensional relationship between the part and the machine tool coordinate system must be coordinated. Moreover, the two steps of positioning and clamping need to be effectively controlled during the clamping process. And also, under the traditional machining process, due to the limited machining capacity of the machine tool itself, it is necessary to perform multiple clamping during the machining process. Moreover, it is necessary to use special fixtures, which leads to higher costs in the design and manufacture of fixtures, and virtually increases the production cost of products. The positioning of the CNC machining process can be debugged by the instrument. In most cases, no special fixture design is required, so the cost is relatively low. This is the second advantage of CNC over conventional machining.
In the process of processing, the choice of tool needs to be determined according to the processing technology and processing method. Especially in CNC machining, the use of high-speed cutting is not only conducive to the improvement of machining efficiency, but also the machining quality can be guaranteed, effectively reducing the probability of cutting deformation and shortening the machining cycle. This is the third advantage of CNC over conventional machining.
