Key indicators and structural design of machining
In the manufacturing process of precision machining, due to its small size, its mechanical properties are good. Precision machining can achieve its fluidity and prevent the formation of bright crystals to a certain extent, generally at a temperature of 715~740℃. The manufacturing temperature of precision machining can ensure that the melt has good fluidity during pouring. The selection of casting temperature needs to be determined based on factors such as the pouring distance and cooling conditions during the pouring process.

Machining processes and technology
Precise machining can be divided into upper and lower die methods, which can be completed through comprehensive processes such as planing, milling, etching, turning, and electric spark. The dimensions and pit shape of precise machining are consistent with the product's edge. When used, because wax molds are mainly used for industrial wax pressing, the melting point and hardness are not high when selecting materials. Aluminum alloy materials with low price and light weight are used for molds.

In the manufacturing process of precision machining, the role of additives is no longer limited to helping the shell quickly establish wet strength; it will also improve the quality of investment casting. The surface quality of the silica sol shell is good at high temperatures. Precision machining has good high-temperature deformation resistance and requires high-precision processes. In practice and theory, we should increase our understanding of precision casting processes, continuously supplement technical attempts, and enrich practical experience.

Surface and solidification knowledge of machining
The finely machined surface will have many dark gray circular shallow pits. Before cleaning, the pits are filled with molten slag, which directly affects the quality of our castings.
