Seibu successfully developed the world's first CNC Wire Electrical Discharge Machine(W-EDM) in 1972.
Then, released new model MB series of high productivity, high precision wire EDM, and MMB and UltraMMB with further improved static accuracy.
In 2016, we released oil-type (oil-working fluid) wire EDM “MEX15” as our new challenge to ultra-precision cutting.
“MEX15” shows strength in the field of narrow pitch connector or lead frame in micro-fabrication using φ0.03 wire.
Straightness less than 0.1μm achieved
Contour shape accuracy ±0.5μm
Pitch accuracy ±0.5μm
Plate cut pitch accuracy ±0.5μm with WC plate (100mm×150mm×8mm)
Roundness 0.4μm
Roundness 0.4μm achieved in complete circle cutting of φ0.07 WC, T=8mm, dia.10mm
Excellent feeding success rate for φ0.03 wire
Cycle time “3 minutes or less” with φ0.03 wire Feeding at wire break point available
