Describe briefly the machining methods of complex parts

The parts with more complicated structure are usually cast by casting or investment casting. Next macro new materials for you to introduce the complex parts of the processing methods.

I. In the processing of parts by is important, its analysis affects the parts clamping. The MIM expert team of daihong new materials found that the clamping error will make the processing process of parts unable to continue to complete, so that the parts can not be completed, so do not underestimate the clamping this link.

1. Basic types of parts:

Dahong new material production of sophisticated parts of the composition of a variety of complex, such as the positive and negative parts with parts, parts table side to process some parts. Therefore, we should analyze the processing route of the parts according to their characteristics.

2. Processing surface of parts:

The selection of machining surface of parts is very important. MIM technicians find that the selection error of machining surface often makes the parts cannot be clamped in the next step, so that the processing of parts cannot continue.

Ii. Briefly introduce the relevant processes of machining parts:

1.The selection of parts processing. The blank data includes the technical and economic characteristics of various blank manufacturing methods; Types and specifications of various profiles, blank drawing, etc. Without blank drawing, we need to know the shape, size and mechanical properties of blank. Different material selection will affect the use of parts, different material selection will make the service life of parts and its production costs become greatly different, so the selection of parts is particularly important.

2. Draw up the process route.

3. Determine the machining allowance of each process and calculate the process size and tolerance.
4. Determine the equipment, fire tools, fixtures, measuring tools and auxiliary tools used in each process.
5. Determine the working time quota.
6.Processing parts.
7. Check the size of parts.
