Wire EDM M50B
High-Speed, high-precision Wire EDM MB SERIES
made the world’s first CNC wire Electrical Discharge Machine (EDM) in 1972. With a fine and silky smooth motion, an electrode wire can cut metal as desired. Our new, innovative technique for high-quality, high-precision cutting is based on the pride in our craftsmanship that has made those characteristics bywords in our company and representative of our products. Seibu will continue to take that extra step in EDM manufacturing to provide our valued customers with innovations and quality arising from the combination of traditional technique and advanced technologies.

High-Precision Wire EDM MB-Series For Ideal Non-Stop-Operetion
An annealing current is repeatedly passed through the wire, and the wire is pulled while being heated to straighten it using our dry annealing method.
This assures the automatic feeding at wire break point nearly 100%. (Patented in Japan, Europe, and the USA)
Top-class AWF (Automatic Wire Feeding Device) supports non-stop operation and greatly improves operation rate.
Operability Improved from User Standpoint
Operability Improved from User Standpoint
It is possible to check the necessary information during cutting or maintenance workon any screen at any time. This saves time for moving to another screen.
Furthermore, it is easy to adjust difficult cutting condition with slider bar without making direct adjustment. This realizes user-friendly operation!.
Simple Attachment for start-hole drilling
Simple Attachment for start-hole drilling
Ana-ake Taro (attachment) is a start-hole drill that can be mounted on all models easily.This can variously help any users in start hole drilling.
CORE STITCH (Patent Pending)
The process of cutting off the cores becomes unnecessary by using this new technology “CORE STITCH” because the cores can be welded at any desired position.
The welded cores can be removed by tapping lightly. So, you can drastically reduce the time for the cutting-off process. (97% Reduction!)
This is the industry’s first technology, and it will revolutionize the efficiency of wire EDM.
EL Coating (Corrosion Resistance of Tungsten Carbide) (Patent Pending)
Coating is given to the cutting surface to prevent the life shortening of metal mold due to corrosion of cemented carbide.
The new technology can cut down the loss of cobalt by 70%, which extends the life of metal mold.
Automatic E-Mail Function
It is possible to monitor various conditions such as [progress], [alarm], [cutting finish], etc. of machine operation status using e-mail by mobile-phone.
