Why do small structural parts need to be processed by car milling
The complex and small structure features require that the turning milling compound processing can be completed after one clamping. The reasons are as follows:
(l) In the process of processing small parts, it is necessary to pick up the lead and multiply when the process is changed between machine tools. Picking up and re clamping will cause the loss of coordinate information, and this part of clamping error will lead to the processing error of parts:
(2) The functional surfaces are small, and the local structural characteristics of some parts have low stiffness and strength. Multiple positioning and clamping are not only unreliable but also easy to cause deformation, which may lead to loss of machining accuracy in the light, or even damage or even scrap the parts in the serious.
To sum up, it is better to process small parts completely. The so-called complete processing is to complete all the processing procedures of complex parts on one machine tool. The complete processing is integrated through the technological process, and the processing process of a part can be completed in one clamping. As the clamping times are reduced, the accumulation of multiple positioning errors is avoided, the machining accuracy, high reliability of the machining process and zero defect production are improved. In addition, the complete turning milling composite processing saves multiple clamping and positioning time, shortens the auxiliary time between the processing chain and each process, reduces the number of machine tools, simplifies the material flow, greatly shortens the processing time, improves the production efficiency, improves the flexibility of the production equipment, reduces the total production area, and makes the investment more effective.
