Meticulous mechanical processing in the production process because of its transition with a small size, so that it will make its mechanical properties good, meticulous mechanical processing can reach its degree of fluidity and does not form bright crystal, the general temperature is 715~740 ℃. The production temperature of meticulous machining can have good fluidity in the process of transferring the melt to a certain extent. In the process of selecting the casting temperature, the equipment needs to be determined according to some factors such as the distance of transferring the melt and the cooling situation in the transferring process.

The melt at the use temperature of meticulous machining will have good fluidity in the process of transfer injection. The selection of meticulous machining temperature should be determined according to some factors such as the distance of transfer injection, the cooling condition of transfer injection process, alloy, specification, flow rate, etc. The crack tendency of the round ingot machined by fine machining is relatively low, so that the alloy has its good exhaust feeding ability to a certain extent, and the order in which it can be created is close to the conditions when it is used, and its density can be increased when it is used, and the casting temperature is generally relatively high.

Machining installation sequence and process

To arrange the detailed machining sequence, we need to follow the basic principles of "surface before hole" and "coarse before fine.

Mechanical processing technology Heat treatment process

With the development of aerospace, industry, microelectronics industry, modern and biological engineering technology, the demand for/detailed mechanical parts (feature size in micron to millimeter level) is increasingly urgent. The specificity of its structure and shape, the diversification of parts and materials, and the accuracy of size and surface quality have become the obvious characteristics of high-precision mechanical parts and their micro-devices and equipment, and the requirements in terms of use function, material characteristics, structure and shape, and sex are also getting higher and higher.

Machining details, forging and casting

In the process of meticulous machining, its mechanical properties are better than cast iron, but the cast iron properties of this material are poor, and the melting point is higher than other materials. There are many problems that need to be paid attention to in the process of processing, mainly because the flow performance of molten steel is relatively poor. In the process of processing, in order to prevent insufficient pouring or cold insulation from meticulous machining, the wall thickness of meticulous machining cannot be less than 8mm. The structural force of the gating system is relatively simple, in the process of using the equipment in the cross-sectional size of cast iron is large, so in the process of processing can also be used in the hot casting mold or dry casting mold.
