CNC machining process from the conventional processing technology, is the conventional processing technology, computer numerical control technology, computer-aided design and manufacturing technology, an organic combination. Due to the continuous development of technology, there are more and more parts that need to be precision machined in the modern manufacturing industry. The machining accuracy and the surface complexity of the workpiece are also getting higher and higher. Therefore, CNC machining has received widespread attention, but cost savings, CNC machining or higher than the traditional processing costs. Here we will specifically introduce the difference between CNC machining and traditional machining process.
1. processing technology
In the general machining process, whether it is positioning, clamping, cutting tools, tools and other aspects can be simplified, but the data processing technology is more complicated, these factors need to be fully considered, and even if the same processing Task, CNC machining process can have a number of programs, you can on a number of processing parts and processing tools as the main line of the process of arrangement, the process has a variety of features, which is the difference between the CNC machining process and the traditional machining process.
2. fixture and fixture
In the CNC machining process, not only need to fix the fixture and the coordinate direction of the machine to ensure a relatively fixed, but also to coordinate the size of the parts and machine coordinate system. And the clamping process requires positioning and clamping the two steps for effective control. And the traditional machining process, due to the limited processing capacity of the machine itself, so the need for multiple clamping during the processing. And the need to use special jigs, which led to the jig in the design and manufacture of higher costs, virtually increase the product cost of production. The CNC machining process positioning can use the instrument to debug, in most cases do not need to carry out a dedicated fixture design, so relatively speaking, the cost is relatively low.
In the process of processing, the choice of tools need to be based on the processing technology and processing methods to determine the different. Especially in CNC machining, the use of high-speed cutting is not only conducive to the improvement of processing efficiency, and processing quality can be guaranteed, effectively reduce the risk of cutting deformation, so that the processing cycle is shortened, so to tell cutting the demand for cutting tools to further increase .
There is also a dry cutting method, this cutting method without cutting fluid or only a small amount of cutting fluid cutting conditions, it requires the tool has good heat resistance. Relative to the ordinary machining process is concerned, CNC machining process on the performance of the tool has higher requirements.
