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.
