- Large-capacity wire-cut EDM with 1200 × 800 mm X/Y travel, 260 × 260 mm U/V travel and 500 mm Z travel, with optional 600 mm and 800 mm Z-axis configurations.
- Designed for very large workpieces, with a maximum workpiece weight of 4000 kg.
- Rigid machine construction incorporates an FEA-optimized casting, extra-wide machine base and rigid U/V truss structure for improved stiffness and machining stability.
- Four-sided stainless-steel worktable with hardness of approximately HRC 50.
- A water-cooled lower arm reduces thermal expansion caused by heat accumulation and helps maintain machining accuracy.
- Precision motion system uses extended linear-guide spacing, C1-class cryogenically treated ball screws, double-end support and high-resolution AC servo motors, supporting micro-step positioning down to 1 μm.
- Laser calibration and pitch-error compensation improve positioning accuracy, while closed-loop X/Y linear scales are available as an option.
- All five controlled axes use AC servo motors.
- High-frequency calculation and pulse-control technology, real-time spark feedback, embedded control hardware and RS-485 communication support stable EDM performance.
- Electrolysis-Free (EF) generator technology and RTS (Real Time Sparking) are designed to improve cutting stability and efficiency.
- Optional Automatic Wire Threading (AWT) supports unattended machining, automatic rethreading at the wire-break point and submerged threading without draining the work tank.
- Water-jet assisted threading supports workpieces up to 500 mm thick. During multi-hole machining, failed threading positions can be skipped automatically, recorded and revisited later.
- Graphical W6 control interface uses an industrial PC and 15-inch LCD touchscreen, with LAN, USB and RS-232 connectivity and a minimum programmable command unit of 0.0001 mm.
- Optional Super Finish Circuit can achieve surface roughness below Ra 0.2 μm under the manufacturer’s specified cutting conditions.
- Standard equipment includes 10 L ion-exchange resin, two paper filters, two diamond guides, two sets of upper/lower flushing nozzles, two energizing plates, one spool of brass wire, one clamping-tool set and one vertical alignment jig.
- Optional equipment includes X/Y-axis linear scales, W-axis, clamping beam, Jumbo Feeder L-50A, Automatic Wire Threading (AWT), double door, 15 kVA AVR, 15 kVA transformer, SMS function, signal tower, remote monitoring system and Super Finish Circuit.
The V1280 is available in Z500, Z600 and Z800 configurations. Maximum workpiece size is 1650 × 1200 × 495 mm, with optional heights of 595 mm or 795 mm depending on the Z-axis configuration. Maximum workpiece weight is 4000 kg, and supported wire diameter is 0.20–0.33 mm. X/Y-axis travel is 1200 × 800 mm, U/V-axis travel is 260 × 260 mm, and Z-axis travel is 500 mm, with optional 600 mm or 800 mm travel.
The machine controls five axes using AC servo motors and provides a maximum taper angle of ±30° per 100 mm when equipped with the wide diamond guide and nozzle.
The V1280 Z500 measures 4400 × 3725 × 2585 mm, while the Z600 version measures 4510 × 3765 × 2890 mm. Excetek does not publish the Z800 overall machine dimensions in the visible specification table, so I would not invent them. Machine weights for the Z500 / Z600 / Z800 versions are 10,600 / 10,850 / 11,600 kg, respectively. Water-tank capacities are 3000 / 3300 / 4000 L.
