1. Processing technology
In the ordinary machining process, both the positioning datum, clamping method, tool, cutting method and other aspects can be simplified, but the data processing process is relatively complex, which needs to be fully considered. In addition, even if the same processing tasks are the same, there can be multiple schemes for aluminum alloy CNC processing, and multiple processing parts and tools can be arranged as the main line in the process. This process has diversified characteristics, which is the most obvious difference between the NC processing technology and the traditional processing technology.
2. Clamping and clamping
In the process of aluminum alloy CNC machining, it is not only necessary to ensure that the coordinate direction of the fixture and the machine tool is relatively fixed, but also to coordinate the dimensional relationship between the parts and the machine tool coordinate system. In addition, it is necessary to effectively control the two steps of positioning and clamping in the clamping process.
In addition, under the traditional processing technology, due to the limited processing capacity of the machine itself, multiple clamping is required during the processing. In addition, special fixtures are required, which leads to higher design and manufacturing costs of fixtures, and actually increases the production costs of products. However, the positioning of the NC machining process can be adjusted by the instrument. In most cases, there is no need to design special fixtures, so the cost is relatively low.
3. Tools
In the process of aluminum alloy CNC machining, the tool selection needs to be determined according to different machining processes and methods. Especially in NC machining, the use of high-speed cutting is not only conducive to improving the processing efficiency, but also can ensure the processing quality, effectively reduce the probability of cutting deformation, and shorten the processing cycle. Therefore, the demand for high-speed cutting tools is further increased.
At present, there is also a dry cutting method, that is, cutting without adding cutting fluid or only using a small amount of cutting fluid, so the tool must have good heat resistance. Compared with ordinary machining process, NC machining process has higher requirements on tool performance. At present, NC machining process has become the main process in the modern machining industry, which has also led to great changes in the tool industry. It is no longer simply used to produce and supply cutting tools, but has begun to transform new cutting processes and related supporting technologies to product development. Tool manufacturers have also become important partners in the current machining industry to improve production efficiency and quality and reduce production costs.
4. Processing method
In the traditional machining process, some machining processes cannot be precisely controlled, so it is not easy to use. However, when machining with CNC machine tools, these carefully used addition methods become feasible. In addition, in the process of aluminum alloy CNC machining, arc interpolation, post processing and NC trimming methods replace the traditional hole positioning methods such as filling, empty tool and trimming.
