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.
After the first two sandblasting and natural air drying, the third sandblasting, the fourth sandblasting, the fifth sandblasting and so on are carried out in turn. Then adjust the number of sandblasting according to the size of its volume, surface requirements and self-weight, etc., generally the number of sandblasting times is 3-7 times.
meticulous machining will coat multiple wax patterns on the fixed die with industrial glue and evenly spray a layer of fine sand, which is very small and fine, so that the surface of the blank can be as smooth as possible. After the fine machining is completed and naturally air-dried, the industrial glue will continue to be applied to the surface of the wax model in the process of use, and then a layer of sand will be sprayed, the particle size is larger and coarser than the previous layer of sand, and the wax model will be naturally air-dried at a set constant temperature after spraying.

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.
