Fine machining in the production process because of the transition of the band size is small, which will make its mechanical properties, fine machining can be achieved to the extent of its mobility and the formation of bright crystals shall not prevail, the general temperature of 715 ~ 740 ℃. Meticulous mechanical processing of the production temperature, to the extent that the melt in the process of reinjection will have good fluidity, equipment in the process of selecting the casting temperature needs to be based on the process of reinjection of the distance as well as reinjection of the process of cooling and other factors to be determined.
Meticulous mechanical processing of the use of temperature of the melt in the process of reinjection will have its very good mobility, choose the temperature of the meticulous mechanical processing should be based on the distance of reinjection, reinjection process of cooling, alloy, specifications, flow rate and other factors to determine. Meticulous mechanical processing of round ingot crack tendency is relatively low, so that there can be to a certain extent of its alloy has its good ability to make up for the shrinkage of the exhaust, in the use of the ability to create the order of its close to the conditions, in the use of the density can be improved, the casting temperature is generally higher.

With the development of aerospace, industry, microelectronics industry, modern and bioengineering technology, the demand for / detailed mechanical parts (feature size in the micron to millimeter level) is increasingly urgent.
Details of machining, forging and casting
In the process of using detailed mechanical processing, its mechanical properties are better than cast iron, but the cast iron properties of this material is poor, the melting point is higher than other materials.
Machined surfaces and solidification knowledge
fine machining processing is convenient, the use of saving its materials, in the process of operation can save its resources, many casting methods can only cast relatively simple castings, and another advantage of fine machining is that complex castings can be cast.
the role of additives in the process of fine machining will no longer be limited to helping the shell quickly build up the wet strength, but also improve the development of its investment casting quality, the surface quality of the silica sol shell is good and its high temperature.
Machining process and technology
fine machining can be divided into upper and lower die methods, which can be completed through comprehensive processes such as planing, milling, etching, turning, and EDM. The size and pit shape of the fine machining are consistent with the edge of the product, mainly because the wax die is mainly used for industrial wax forming, so its melting point is not high and the hardness is not high when selecting, and the aluminum alloy material with relatively cheap and light weight is used as a mold.
