EA28V Advance Sinker EDM

Heavy duty, large part and mold machine – many productivity options, ideal for special applications.

The entry point in our EA-V series of medium-size sinker EDM machines, the EA28V Advance allows for the high-speed machining of tungsten carbide with copper tungsten electrodes. But this machine can deliver much more than precision performance.

The EA28V also comes equipped with internal components and processes designed to give you the highest return possible on your machine investment—through lower energy usage, increased productivity due to minimal downtime, less material consumption, and more.

RELIABILITY THAT MAKES THE CUT

  • Highly durable components keep maintenance costs in their place while meeting project requirements.

ADDED FUNCTIONALITY

  • The addition of tungsten carbine machining on top of standard sinker EDM capabilities makes the EA28V a smart, versatile investment.

ENGINEERED FOR EFFICIENCY

  • Managing your profit margins is now easier than ever, thanks to the suite of cost-saving innovations that come as stock on the EA28V.

CAPABILITIES:

  • FP120V energy-saving power supply reduces electrical consumption by 20% compared to previous models
  • This standard V-series power supply also helps reduce electrode wear by as much as 50% when machining tungsten carbide, leading to longer tool life and less time and money spent on maintenance
  • SS Jump 5 system grants users greater acceleration control to stabilize high-speed no-flush burning
  • Can produce a variety of finishes, including:
    • Fine matte finishes with the PS circuit
    • Super-low wear with the SC circuit
  • Fuzzy Pro Plus enables greater hands-off operation for better usability

COMPONENTS:

  • New high-speed “V” power supply (standard FP120V or optional FP80V)
  • Compact, highly rigid machine design
  • Fixed table traveling column construction
  • Thermal displacement compensation control
  • Direct drive AC smart servo system
  • 3D lateral servo system
  • All-axes linear glass scale feedback
  • 3-sided drop tank access
  • Easy-access dual-filter system
  • Dielectric fluid chiller standard
  • New high-inertia-style C axis
  • Multiport flushing manifold
  • 36-position multistep rise-and-fall worktank

ON-BOARD AUTOMATION:

  • Automatic lubrication system

USER INTERFACE:

  • M700 series CNC control with 15″ touchscreen
  • Standard USB and Ethernet data inputs

SYSTEM INFORMATION:

  • Windows XP-embedded operating system
