Mitsubishi Electric FA30 Advance

ADAP (Adaptive) technology continuously monitors the inter-electrode gap voltage during each cutting pass and adjusts generator pulse energy, servo feed rate, and flushing parameters in real time. When the machine encounters thicker workpiece sections, interruptions in cut (from holes or slots), or areas of chip accumulation, ADAP responds without operator input to maintain stable cutting speed and consistent surface finish. This reduces total cut time on complex die profiles by preventing the speed reductions that fixed-parameter generators apply defensively.

Both machines offer 600 x 400 mm X/Y travel and handle similar large die and mold work. The primary technical difference is axis drive: the AG600L uses Sodick's all-axis linear motor drive, while the FA30 Advance uses a precision ballscrew system. Linear motors provide theoretically zero backlash and no mechanical wear, while Mitsubishi's ballscrew design uses high-precision ground ballscrews with anti-backlash preloading. In practical production conditions, both achieve high accuracy. The Mitsubishi has strong brand recognition in the EDM market and a long service history.

The FA30 Advance's water-jet and electrical discharge threading system reliably threads wire through start holes with a minimum diameter of approximately 0.4 mm. For holes smaller than 0.4 mm, threading reliability decreases. The electrical discharge assist feature fires small EDM pulses to help guide the wire into very small holes — a capability that standard water-jet-only threaders lack.

Yes. The FA30 Advance is designed for unattended production. Automatic wire re-threading at break points, the ADAP adaptive generator for stable cutting through variable conditions, and the V500 controller's production monitoring system collectively enable overnight unattended operation on multi-part and multi-cavity programs. Wire spool capacity supports many hours of continuous operation before manual wire loading is required.

For maximum rough-cutting speed on 50 mm steel, 0.25–0.3 mm coated wire provides the best material removal rate, with coated wire delivering 15–25% higher speed than bare brass on equivalent settings. For skim passes targeting Ra 0.1–0.3 µm, 0.2 mm wire is standard. For fine finishing below Ra 0.15 µm or narrow slot features, 0.15 mm wire is preferred. The V500 condition database guides optimal wire selection per application.
