Processing method for complex parts


The structure of the more complex parts are generally precision casting or investment casting process. Here zcmim powder metallurgy to introduce the processing methods of complex parts there.

Part structure analysis
The analysis of the components in the processing of parts by important, it analysis the influence to the parts clamping. Don't underestimate this link clamping. Often put clip mistakes can make the machining process can not continue down, so that the parts can not be completed.

1, the basic types of parts
(1) parts of the composition of a variety, such as the pros and cons of mating parts, parts of the surface of the main surface of the parts to be processed parts. First, we should according to the characteristics of the parts to analyze the processing route of the parts.

2, parts of the processing surface
(2) the selection of parts of the processing surface is very important, often the wrong choice of the processing surface so that parts can not be installed in the next step, so that parts processing can not continue.

Two, a brief introduction of the processing parts of the relevant processes
1, part of the processing of material selection
Blank data including all blank manufacturing methods of technical and economic characteristics of various profiles of varieties and specifications, rough map; under no blank map, practical understanding of the blank shape, size and mechanical properties of the. Different material will affect the components and different material will make the service life of the parts and the production cost is greatly different, so parts of the material is especially important.
2, to develop the process route.
3, determine the machining allowance of each process, calculate the working dimensions and tolerances.
4, determine the various processes used in the equipment and tools, fixtures, measuring tools and auxiliary tools.
5, determine the time quota.
6, processing parts.

7, check the size of the parts.a
