Electric Discharge Machine > SuperMMA Series Seibu successfully developed the world's first CNC Wire Electrical Discharge Machine(W-EDM) in 1972. Then, we released new model M series of high-speed, high-precision wire EDM and MM series with improved static accuracy in 2003, then released ultra-precision wire EDM “MP250S” in 2005. In 2009, SuperMM series was born as more sophisticated ultra-precision model. Pitch accuracy of 2µm can be consistently achieved with SuperMM series that has traditional scraping technique “KISAGE”. We are sure our customers will be very satisfied with Super MM series by the marvelous cost-benefit performance. Pitch cutting accuracy beyond MM series has been realized. Workpiece material:SKD-11 Thickness:20mm Number of cuts:5 times Wire diameter:φ0.2mm Surface roughness:Ra0.21µm /Rz1.76µm 3D measuring instrument:ZEISS In the pitch cutting with the above stroke, we accomplished the accuracy of 1.3µm of error range for X axis and 1.0µm of error range for Y axis. Tremendous “Ultra high-precision cutting” has been realized. The most reliable AWF and the best pitch accuracy and shape accuracy will be a great help in the improvement of quality and productivity for customers. Can meet ultra-precision metal mold! Operator can do cutting such as progressive plate cutting with confidence by use of the world’s top-class AWF. Available for automatic wire feeding of φ0.05 wire! (The performance is more than 90%!) φ0.05 wire that is absolutely necessary for ultra-precision and microfabrication became available in SuperMM series. Human hair is 80µm~100µm, but it is possible to feed thinner wire of 50µm to the start hole of 80µm. One SuperMM machine can support users in various fields not only in ultra-precision cutting but small size precision parts cutting as well.
