Milling technology
The advancement of milling technology is one of the key factors in the rapid development of the manufacturing industry. From the initial ordinary milling machine to the three-axis machining center, and then to today's five-axis high-speed milling technology, milling makes it possible to process complex three-dimensional surface parts.
High-speed milling uses a small-diameter milling cutter, combined with high speed and small cycle feed rate, which significantly improves production efficiency and stabilizes the processing accuracy within 5μm. Due to the low milling force, the thermal deformation of the workpiece is reduced, and the surface finish can reach Ra<0.15 μm. High-speed milling can even process hardened mold steel parts with a hardness of up to 60HRC, which allows the mold to be directly cut after heat treatment, simplifying the manufacturing process.
The application of five-axis machining technology in milling makes the machining of complex curved surfaces and multi-angle parts more efficient and accurate. Through the linkage of five axes, the tool can contact the workpiece from more angles, reducing the need for multiple clamping and position adjustment, greatly improving machining efficiency and surface quality. This technology is particularly suitable for the manufacture of complex molds, and can complete the machining of complex geometric shapes in one go, significantly optimizing the production process and reducing the workload of subsequent processing.
The world's leading milling equipment manufacturers include Swiss GF Machining Solutions (Mikron), Japanese Makino, Japanese Yasuda Asta, Japanese Yamazaki Mazak, German Rhodes, American Haas, etc. These equipments play an important role in precision mold processing, ensuring high-quality and efficient production.
