The precision machining process mainly includes the following types:
1. CNC machining: CNC machine tools use computer programs to automatically control the machining process and can achieve the machining of complex shapes. The application of numerical control technology has improved production efficiency and machining accuracy, and is the mainstream method of modern precision machining.
2. Wire cutting: Wire cutting technology is mainly used for processing materials with high hardness, such as metals and alloys. Through the principle of electric discharge, wire cutting can achieve high-precision cutting and is widely used in mold manufacturing and the processing of complex parts.
3. Laser processing: Laser processing technology has the characteristics of high energy density and high precision, and is suitable for cutting, drilling, and surface treatment of thin plate materials. Laser processing has been widely used in industries such as electronics and automobiles.
4. Grinding processing: Grinding processing is a precision machining process that uses abrasives to process the surface of workpieces, suitable for parts with extremely high requirements for surface quality and dimensional accuracy. Grinding processing is commonly used for machining parts such as shafts, planes, and inner holes.
5. Milling: The advancement of milling technology is one of the key factors driving the rapid development of the plastic mold manufacturing industry. High speed milling uses small-diameter milling cutters, combined with high-speed and small cycle feed rates, significantly improving production efficiency and stabilizing machining accuracy within 5 μ m.
6 . Slow wire cutting processing: mainly used for the processing of two-dimensional and three-dimensional straight surface parts, especially in the manufacturing of stamping dies, which occupies an important position. Slow wire cutting is a high-precision machining method that can achieve a machining accuracy of less than 3 μ m.
7 . Electric discharge machining: Electric discharge machining (EDM) is an ideal choice for processing complex shapes, narrow gaps, deep cavities, and other parts of molds. When traditional cutting tools cannot come into contact with complex surfaces, electrical discharge machining can provide an effective solution.
These processes each have their unique advantages and application scenarios in precision parts machining, and selecting the appropriate process can improve production efficiency and machining accuracy.
