Fully Automatic CNC EDM Wire Cutting Machine DK7750HC
High precision cutting with superior surface roughness for
industrial manufacturing applications.
DK77HC Medium Speed Wire EDM
The DK77HC medium speed EDM wire cutting machine features servo
motors on X and Y axes, electrical hand wheel for smooth axis
movement adjustment, and a verified frequency converter to control
molybdenum wire reciprocation. This ensures exceptional cutting
surface quality around Ra1.0 micrometers and cutting accuracy of
0.01mm.
Key Performance Advantages
- Precision accuracy: ≤0.01mm
- Surface roughness: Ra0.8-1.0μm
- Double-tempered bed and workbench for enhanced structural stability

Control Cabinet
The middle wire control system represents our latest generation of
CNC technology, developed specifically for current market
requirements. This integrated system combines high-frequency power
supply with stepper or optional servo motor drive power supply.
Utilizing digital integrated circuits and high-power VMOS tubes, it
delivers stable performance, user-friendly operation, and high
processing efficiency.
Key control system features include centralized operation buttons
within computer software, intuitive parameter adjustment,
simplified wiring, improved output waveforms, reduced electrode
wire loss, and enhanced cutting efficiency. The system
automatically saves parameter modifications with memory retention
during power outages, significantly improving reliability. It also
includes concise IO monitoring for real-time machine tool condition
reading.

Frequently Asked Questions
What factors should I consider when selecting the right machine?
Match the worktable travel and cutting capacity to your workpiece
size and thickness. Verify whether the precision and surface finish
meet your standards.
The standard voltage in our country is three-phase 220V, but your
machine uses three-phase 380V. Is voltage adjustment possible?
Absolutely. We can customize the machine according to your specific
voltage requirements.
What details do you need from us to prepare a proposal?
We need 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.
