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, UltraMMB was born as more sophisticated ultra-precision model.
Pitch accuracy of 2μm can be consistently achieved with UltraMMB that has traditional scraping technique “KISAGE”.
We are sure our customers will be very satisfied with UltraMMB by the marvelous cost-benefit performance.
Cutting accuracy beyond MM series
Pitch cutting accuracy beyond MM series has been realized.
In the pitch cutting with the above stroke, we accomplished the accuracy of 1.4μm of error range for X axis and 1.2μm 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.
φ0.05 wire that is absolutely necessary for ultra-precision and microfabrication became available in UltraMMB.
Human hair is 80μm~100μm, but it is possible to feed thinner wire of 50μm to the start hole of 80μm.
One UltraMM machine can support users in various fields not only in ultra-precision cutting but small size precision parts cutting as well.
