In the manufacture of precision molds, a variety of advanced processing technologies play a key role.
1. CNC milling
CNC milling technology, especially five-axis high-speed milling, makes it possible to process complex three-dimensional surface parts. The combination of small-diameter milling cutters, high speed and small cycle feed rate significantly improves production efficiency. The machining accuracy can be stabilized within 5μm and the surface finish can reach Ra<0.15μm. In addition, the application of five-axis machining technology further improves the machining efficiency and accuracy of complex surfaces and multi-angle parts.
2. Slow wire cutting
Wire cutting is mainly used for the processing of two-dimensional and three-dimensional straight surface parts, such as punches and dies of stamping dies. Its processing precision is high. High-end equipment can achieve a processing precision of less than 3μm, and the surface roughness can reach Ra0.05μm. It is an indispensable technology in mold manufacturing.
3. Electrical discharge machining
Electrospark machining is suitable for processing complex shapes, narrow gaps, deep cavities and other parts of the mold. Advanced EDM equipment can achieve mirror EDM with extremely high machining accuracy and surface quality, and is particularly suitable for the machining of micro parts.
4. Grinding Machine Processing
Grinding machines are key equipment for finishing the surface of parts, especially for hardened workpieces. The development of modern surface grinders, universal internal and external cylindrical grinders and coordinate grinders has greatly improved machining accuracy and surface quality.
5. CNC lathe processing
CNC lathes are mainly used to process various rotating parts, and their processing accuracy and manufacturing technology are becoming more and more perfect. Advanced CNC lathes have been expanded into turning and milling combined machine tools, which can complete all processing of complex, multi-process parts in one go.
6. High-precision measurement technology
High-precision measuring equipment plays an important role in every stage of precision mold manufacturing. The extensive application of equipment such as three-coordinate measuring machines and image measuring instruments ensures the quality and precision of the molds.
7. Rapid clamping and positioning system and automation
The application of quick clamping and positioning system and automation has significantly improved the production efficiency of precision mold manufacturing. Through precise datum interchange and the establishment of automated production lines, mold manufacturing cycles can be shortened and production costs can be reduced.
These advanced processing technologies have jointly promoted the development of the precision mold manufacturing industry and provided strong support for the development of modern industry.
