Mould manufacturing technology modernization is the basis for the development of the mould industry. With the development of science and technology, advanced technologies such as computer technology, information technology and automation technology are constantly penetrating, crossing and integrating with traditional manufacturing technology, implementing transformation to form advanced manufacturing technology. The new stamping in-mould tapping technology has guided many stamping manufacturers to reduce costs, causing a rush to buy.
The development of advanced manufacturing technology for moulds is mainly reflected in: high-speed milling processing
Ordinary milling uses a low feed rate and large cutting parameters, while high-speed milling uses a high feed rate and small cutting parameters. high-speed milling has the following characteristics compared to ordinary milling: a. High efficiency
a. High-speed milling spindle speed is generally 15000r/min ~ 40000r/min, up to 100000r/min. in cutting steel, its cutting speed is about 400m/min, 5 to 10 times higher than the traditional milling process; in the processing of mold cavities and traditional processing methods (traditional milling, EDM processing, etc.) compared to its efficiency increased by 4 ～To 5 times.
b. High precision High-speed milling accuracy is generally 10μm, some precision is also high.
c. High surface quality Due to the small temperature rise of the workpiece during high-speed milling (about 3°C), there is no surface degradation layer and micro-cracks, and the thermal deformation is also small. The best surface roughness Ra is less than 1 μm, which reduces the subsequent grinding and polishing workload.
d. Can machine high hardness materials Can mill steel from 50 to 54 HRC and mill up to 60 HRC.
In view of the above advantages of high-speed machining, so high-speed machining in mould manufacturing is being widely used, and gradually replace part of the grinding process and electric machining
