Machining details, forging and casting

2024/06/04

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.

The temperature determines the good fluidity of the melt in the transfer process. The selection of the detailed machining temperature should be determined according to the distance of the transfer, the cooling situation during the transfer process, the alloy, the specification, the flow rate and other factors. The detailed machining temperature is 50 to 110 ℃ higher than the liquidus temperature of the alloy. The production temperature can determine that the melt will have good fluidity in the process of transfer injection. In the process of selecting the casting temperature, the equipment needs to be determined according to some factors such as the distance of transfer injection and the cooling of transfer injection process.

What are the factors that affect high product components?

Machining has been used in many applications, because the current mechanical manufacturing requirements for output has declined, the requirements for size and shape have gradually increased, and high-product parts have a new development trend. The use of lathes requires different turning methods, but grinding, cutting, milling and other processes can be carried out in one lathe, and the development trend of process integration is more obvious.

Precautions and industrial requirements for detailed machining

Fine machining is a kind of casting process with little or no cutting. It is a good process technology in the casting industry, and its application is common. The reasons for choosing meticulous machining are as follows

"Machining" surface treatment

The manufacturing precision of meticulous machining is high, and the surface of the product is smooth during the use of the product, which means that the meticulous machining produced can save a lot of machining work and can be directly used in life. There will be many gray-black round shallow pits on the surface of meticulous machining. The pits will be filled with slag substances before the equipment is cleaned. The degree of these substances will directly affect the quality of our castings.

Machining Important Index and Structure Design

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 the degree of its 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.
