machining has been used in many ways, because the current mechanical manufacturing requirements for output have decreased, the requirements for size and shape have gradually increased, and there is a new development trend for high-quality parts. The use of lathes requires different turning methods, but processes such as grinding, gear cutting, and milling can be carried out in a single lathe, and the trend of integration of this process is obvious.
In the process of tempering high-quality product parts, the stress generated during quenching can be to a certain extent, the decomposition and transformation of martensite and residual austenite metastable structure after quenching, and the temperature of product tempering is usually below the eutectic transition temperature, which is about 650 °C, and the holding time is not less than 2h. The
production temperature of high product parts can be determined to the extent that the melt will have good fluidity in the process of transfer, and the equipment needs to be determined according to some factors such as the distance of its transfer and the cooling in the process of transfer.
When the geometric parameters of the tool are processed in the operation of the high-product parts, the geometry of the cutting part of the product tool should generally be considered from the selection of the rake angle and the rear angle, and the requirements of the surface roughness of the cutting part of the high-product parts can reduce the resistance of the chip when the chip is curled, and the degree of the tool can be improved.

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.
