DK7780A 3-Axis CNC Machine Auto Wire Feed High Column Electric Lift EDM with PLC Motor Pump-Wire Electric Wire Cutter
Product Features
High-speed cutting performance - Maximum cutting speeds up to 170-350 mm²/min depending on surface finish requirements, with regular stable speeds around 170 mm²/min at 6-8A current. Accelerates production cycles for die and mold shops.
Exceptional precision and finish - Machining accuracy of ±0.015-0.02mm per GB7926-2005 standards, with surface finish as low as Ra≤1.5μm on multi-cut operations and Ra≤2.5μm on single cut. Parts often come off the machine ready for use without secondary polishing.
Rigid and stable construction - Built with resin sand cast iron bed that undergoes double aging heat treatment, ensuring minimal deformation and long-term stability under heavy loads. Maintains accuracy through years of service.
Intelligent CNC control - Features PC/104 industrial-grade motherboard with graphic tracking, symmetric processing, arbitrary rotation, power-out memory, automatic short-circuit recovery, broken wire protection, and auto-shutoff after finishing. Supports CAD file import and one-click operation.
Low operating cost - Molybdenum wire wear is only 0.01mm after processing 500,000 mm² of material. Resistorless design reduces power consumption up to 1.5-2 kW, saving 70% on electricity compared to conventional machines.
Versatile taper cutting - Standard ±6°/80mm taper, with optional expansion to ±15°, ±30°, or ±45° for complex tapered geometries in a single setup.
Large capacity for heavy workpieces - Worktable size up to 880*1440mm with XY travel up to 800*1200mm, accommodating workpiece height up to 600-800mm and load up to 1500kg. Handles oversized dies and molds with ease.
Wide material compatibility - Cuts any conductive metal including hardened steel, carbide, stainless steel, titanium, and superalloys with zero mechanical stress.

Frequently Asked Questions
What factors should I consider when selecting the right machine?
When choosing a machine, first match the worktable travel and cutting capacity to the size and thickness of your workpiece to identify a suitable model. Additionally, verify whether the precision and surface finish meet your standards.
The standard voltage in our country is three-phase 220V (or single-phase 220V, etc.), but your machine uses three-phase 380V. Is voltage adjustment possible?
Absolutely. Just let us know your specific voltage requirements, and we can customize the machine accordingly.
What details do you need from us to prepare a proposal?
We'll need the worktable dimensions, required travel range, and any special requirements you may have.
Are you a manufacturer or a trading company?
We specialize in manufacturing CNC machine tools and have over 20 years of experience in this industry.
