Mechanical Processing and Installation Sequence and Procedures

When arranging the sequence of precision machining operations, it is necessary to follow the basic principles of "surface first, then holes" and "roughing first, then finishing."

Mechanical Processing Technology – Heat Treatment Processes

With the advancement of aerospace, industrial, microelectronics, modern, and bioengineering technologies, the demand for highly precise mechanical components—whose feature sizes range from micrometers to millimeters—is becoming increasingly urgent. The specialization of their structural shapes, the diversification of component materials, and the continuous improvement in the precision of dimensions and surface quality have become distinctive features of high-precision mechanical components as well as miniature devices and equipment. Consequently, the requirements in terms of functional performance, material properties, structural design, and reliability are also steadily rising.

Mechanical processing details, forging and casting

During the process of precision machining, this material exhibits superior mechanical properties compared to cast iron; however, its casting performance is inferior to that of cast iron, and its melting point is higher than that of other materials. There are numerous issues that need to be carefully considered during machining, primarily because the fluidity of the molten steel is relatively poor. To prevent insufficient filling or cold shuts during precision machining, the wall thickness of the workpiece must not be less than 8 mm. The structure of its gating system is relatively simple, and when in use, the cross-sectional dimensions of the equipment should be larger than those used for cast iron. This allows for the adoption of either hot-box molding or dry-box molding during the machining process.

Surface and Solidification Knowledge in Mechanical Machining

The surfaces of finely machined parts often exhibit numerous light, circular depressions that are grayish-black in color. Before the equipment is cleaned, these depressions become filled with slag-like material, which can significantly affect the quality of our castings.

Mechanical machining process

During the precision machining process, the role of additives will no longer be limited to merely facilitating the rapid development of a wet strength in the investment mold shell; instead, they will also contribute to enhancing the quality of lost-wax casting. Silica sol-based mold shells exhibit excellent surface quality and high-temperature performance. Precision machining boasts good resistance to deformation at high temperatures, making it suitable for products that demand relatively high precision. Both in practice and theory, it is essential to deepen our understanding of precision casting processes, continuously refine our technical approaches, and enrich our practical experience.

Machining Processes and Techniques

Fine mechanical machining can be categorized into upper-and-lower cavity die methods and is typically accomplished through a combination of processes such as planing, milling, etching, turning, and electrical discharge machining. The dimensions and pit shapes of fine mechanical machining are consistent with those of the product’s edge profile. When selecting materials for this process, since wax molds are primarily used for industrial wax casting, it’s important to choose aluminum alloy materials that have a relatively low melting point and moderate hardness. These materials are cost-effective and lightweight, making them ideal for mold fabrication.

What factors influence high-performance components?

Cutting processes have already found wide applications in numerous fields. As current mechanical manufacturing places decreasing demands on production volume but increasingly higher demands on dimensions and shapes, there’s a new trend emerging in the development of high-performance components. While turning operations require different turning methods, processes such as grinding, gear cutting, and milling can now be carried out on a single lathe. The trend toward integrated machining processes is becoming increasingly evident.

Mechanical Machining Surface Treatment

The manufacturing precision of fine mechanical machining is high, and during use, the surface of the product remains smooth and polished. In other words, fine mechanical machining can significantly reduce the need for additional mechanical processing steps, allowing these parts to be directly put into practical applications. The surface of finely machined components often features numerous light, circular depressions that are grayish-black in color. Before the equipment is cleaned, these depressions become filled with slag-like material. Such material, to a certain extent, directly affects the quality of our castings.

Key Performance Indicators and Structural Design in Mechanical Processing

During the manufacturing process, fine mechanical machining features small transitional dimensions, which contribute to its excellent mechanical properties. In fine mechanical machining, fluidity can be achieved to a certain extent, with the goal of avoiding the formation of bright crystals; the typical temperature range is 715–740°C. The optimal processing temperature for fine mechanical machining ensures that the molten material exhibits excellent fluidity during the pouring process. When selecting the casting temperature, equipment designers must take into account factors such as the pouring distance and the cooling conditions encountered during the pouring process.
