Machining process and technology

2024/06/04

Meticulous machining can be divided into upper and lower concave mode, which can be completed through its planing, milling, etching, turning, electric spark and other comprehensive processes. The size of the meticulous machining and the shape of the pit are consistent with the plate edge of the product. When in use, the wax mold is mainly used for industrial wax pressing, so its melting point is not high and its hardness is not high when selecting. When in use, the aluminum alloy material with relatively cheap price and lighter weight is used as the mold.

After the first two sandblasting and natural air drying, the third sandblasting, the fourth sandblasting, the fifth sandblasting and other processes are carried out in turn. Then according to the size of the volume and the surface requirements and weight of the corresponding adjustment of the number of sandblasting, the number of sandblasting in general is 3-7 times.

Meticulous machining will coat multiple wax molds on the fixed die with industrial glue and spray a layer of fine sand evenly. The sand particles are very small and fine, so that the surface of the blank can be as smooth as possible. After the fine mechanical processing is completed by sandblasting and natural air drying, industrial glue will continue to be applied to the surface of the wax model during use, and then a layer of sand will be sprayed, the particle size of which is larger and thicker than the previous layer of sand. After spraying, the wax model will be allowed to dry naturally at the set constant temperature.

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.
