Controlled machining and machining is now hardware processing often used in the processing technology, CNC machining process from the conventional processing technology, which belongs to the conventional processing technology and computer numerical control technology, computer-aided design and assisted manufacturing technology, because of the continuous development of technology, the modern manufacturing industry in the need for precision machining of parts and components more and more, the processing accuracy and processing of parts and components with surface Complexity requirements have become increasingly high, so CNC machining will often get a wide range of Zhuan Yu, but from the cost point of view, the cost of CNC machining than the traditional machining process costs are higher, the next follow HongWeiSheng Precision Technology to look at, cnc CNC machining with the traditional machining process what are the differences: Translated with DeepL.com (free version)
1、Difference in processing technology
In the conventional machining process, whether it is the positioning of the reference or clamping, machining tools and cutting methods and other aspects can be simplified, but the data machining process will be more complex, the need for these many factors to be fully considered, and because of the use of the same machining tasks, CNC machining process can be many product solutions, can be more than one machining complementary and machining Tool to make the main line for the process arrangements, the process has a diverse range of characteristics, which is the difference between the CNC machining process and the traditional machining process;
2、Difference between clamping and fixture above
In the CNC machining process, not only do we need fixtures and equipment to maintain a relatively fixed coordinate direction, and also to coordinate the dimensional relationship between the parts and equipment coordinate system, the clamping process needs to be positioned and clamping of these two steps for effective control, the traditional machining process conditions, because of their own equipment processing capacity is relatively limited, so it is necessary to be carried out in the machining process for many times. Clamping, and also need to use to the special fixture, which led to the fixture in the design and manufacturer’s cost is relatively high, invariably increase the production cost of the product, but the CNC machining process positioning to use the instrument to debug, in many cases do not need to carry out the design of a special fixture, so, comparatively speaking, the cost of its lower;
3、Difference in the use of tools
In the process of processing, tool selection needs to be based on the difference between the processing technology and processing methods to determine, especially in the process of CNC machining, the use of high-speed cutting is not only conducive to the efficiency of the processing and the quality of its processing is also more guaranteed to effectively reduce the chances of deformation caused by cutting, so that the cycle of processing is shorter, so in the high-speed cutting under the higher demand for cutting tools;
At present, in the international field of machining there is a dry cutting method, this cutting method in the absence of cutting fluid or only a small amount of cutting fluid for cutting, so the need for tools with excellent heat resistance, relative to the ordinary machining process, CNC machining process for the performance of the tool has higher requirements;
