Oil-type Wire Electric Discharge Machine

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.

SEIBU MADE THE WORLD'S FIRST CNC WIRE ELECTRICAL DISCHARGE MACHINE

FEATURES

Straightness less than 0.1μm achieved

High rigidity virtual cross table with “seal-less structure” has been employed, which realizes the straightness less than 0.1μm for both X,Y axes.

Contour shape accuracy ±0.5μm

Contour shape accuracy ±0.5μm in lead frame cutting.

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
