The related role of machining

A good mold or finished product is inseparable from related processing steps. Regarding the craftsmanship, this has a close connection and function with the production equipment. In this regard, having a high-quality production configuration is also a key factor. Regarding the procurement-related production configuration, a large number of external factors need to be referred to before the appropriate configuration can be selected. For example, whether its quality meets international standards, whether its material meets relevant requirements, and whether its basic framework is developed in accordance with relevant production standards. In addition, the price of these tools is also a major factor affecting customer purchases. Processing technology refers to various processing technologies whose processing accuracy and surface finish are higher than those of the corresponding processing methods. The processing technology includes cutting processing (such as diamond boring, turning, wide-edge precision planing, etc.) and high-brightness and high-precision grinding. The machining accuracy is generally 10~0.1μm, the tolerance level is above IT5, and the surface roughness Ra is below 0.1μm.

Cutting is a process of cutting a very thin layer of metal on the surface of the workpiece with a high or very low cutting speed, a very small depth of cut and a feed rate with a high-precision, high-rigidity machine tool and finely sharpened tools. Obviously , This process can significantly improve the machining accuracy of parts. Due to the small residual area in the cutting process, and the maximum elimination of the adverse effects of cutting force, cutting heat and vibration, it can effectively remove the surface deterioration layer left by the previous process, and the surface after processing is basically free of residual tension. The stress and roughness are also greatly reduced, which greatly improves the quality of the processed surface. High-gloss and high-precision grinding includes grinding, super grinding and mirror grinding. High-brightness and high-precision grinding also requires the machine tool to have high precision and rigidity. The grinding process uses a finely trimmed grinding wheel to produce multiple micro-cutting edges of equal height on each abrasive grain for very small grinding. Depth, under appropriate grinding pressure, very fine chips are cut from the surface of the workpiece plus the friction when the micro cutting edge is in a micro state, squeezing, smoothing, and friction during multiple non-feed smooth grinding stages Polishing effect, so as to obtain a high processing accuracy and a high-gloss and clean surface with good physical and mechanical properties. In summary, the use of processing technology can comprehensively improve the processing accuracy and surface quality of the workpiece.
