What are the factors affecting high-value parts?
Cutting processes have been widely applied due to the decreasing demand for productivity and the increasing demand for dimensional accuracy and shape in modern mechanical manufacturing, leading to new development trends in high-precision parts. Different turning methods are required when using lathes; however, the integration of processes such as grinding, gear cutting, and milling on a single lathe is a clear trend.

Precautions and industry requirements for precision machining
Fine machining is a casting process with little or no cutting, a superior technology in the foundry industry with widespread application. Reasons for choosing fine machining are as follows

Surface treatment of "machining"
The manufacturing precision of fine machining is high, and the surface of the product is smooth during use, which means that the fine machining produced can save a lot of machining work and can be directly used in life. The surface of fine machining will have many gray-black circular shallow pits. Before the equipment is cleaned, the pits are filled with molten slag. These substances will directly affect the quality of our castings to a certain extent.

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.
