What should I pay attention to for high strength edge cutting die?
Edm grinding (also known as edm generative machining) is a significant development of edm technology, which is a new technology to replace the traditional process of mold cavity with formed electrode.Just like CNC milling, spark grinding USES high-speed rotating rod-shaped electrodes for two-dimensional or three-dimensional contour machining of the workpiece. High-strength edge-cutting dies need to pay attention to what does not require the manufacture of complex and expensive shaped electrodes.The EDSCAN8E spark launched by mitsubishi corporation of Japan creates a machining machine tool, which is equipped with automatic electrode loss compensation system, CAD/CAM integrated system, online automatic measurement system and dynamic simulation system, which reflects the current level of edm into machining machine tools.The development level of CNC wire cutting technology has been quite high, the function is quite perfect, the degree of automation has reached the level of unmanned monitoring.The maximum cutting speed has reached 300mm2/min, the machining accuracy is up to ± 1.5m, and the surface roughness is up to Ra0.1.0.2 microns.The development of wire cutting technology with a diameter of 0.03-0.1mm can realize the completion of a single cutting in the concave and convex mode, and can carry out the cutting processing of 0.04mm narrow groove and the round corner within the radius of 0.02mm.Tapered cutting technology has been developed for precision machining of slopes above 30°.Due to the characteristics of high precision, good surface quality and low surface roughness, the grinding and polishing technology of grinding and grinding has been widely used in precision mold processing.Advanced equipment and technologies such as NC shape grinder, NC optical curve grinder, NC continuous track coordinate grinder and automatic grinding machine are widely used in the manufacture of precision mould.The complexity of product structure measured by numerical control will inevitably lead to the complexity of mold parts shape.Traditional geometric inspection methods can no longer adapt to mold production.The manufacture of the current mould has widely used the three-coordinate numerical control measuring instrument to measure the geometry of the mould parts.In addition to measuring data of complex surface with high precision, the three-coordinate numerical control measuring instrument also carries out automatic inspection on the site through its good temperature compensation device, reliable anti-vibration protection ability, strict dust removal measures and simple operation steps.The application of advanced mould manufacturing technology makes the mould quality of traditional mould making technology depend on human factors and change the situation that is difficult to control. The quality of mould depends on physical and chemical factors. The overall level is easy to control and the reproducibility of mould is strong.
