-Wire Cut For Metal/Electric Discharge Machining

EDM Metal Cut Machine Brief Description

EDM Wire Cutting is a type of mechanical equipment that utilizes the principle of electric spark discharge for metal cut.

It generates electric sparks in a working fluid and uses the high temperature and energy characteristics of the sparks to melt and corrode metal, achieving cutting, processing, and shaping of metal materials. This cutting method is commonly employed for processing hard alloys, mold steel, and other challenging materials, offering high precision and efficiency.

Unique advantages of the DK 7745 EDM Metal Cut Machine

  1. “pyramid” cross slide structure bed, box structure design, the machine tool has sufficient static and dynamic stiffness, reliable operation, simple operation, convenient maintenance, and conforms to the principle of ergonomics;
  2. All castings are cast by resin sand process, with long-time natural aging, secondary tempering and complete elimination of internal stress, which improves the rigidity and precision retention of castings; The rigidity of the edm wire cutting machine tool is increased and the deformation is reduced.
  3. The guide rail is made of bearing structural steel, and the quenching hardness is between hrc56 and 60, ensuring the wear resistance of the guide rail.
  4. The lead screw adopts ball lead screw with high rolling accuracy and strong wear resistance.
  5. The worktable and wire carriage are rolled with precision rollers respectively, with smallfriction, stable movement and strong wear resistance.
  6. All machine tool components and parts are finished by high-end processing equipment such as large grinder and precision machining center to ensure the geometric accuracy and matching accuracy of parts
  7. The workbench is equipped with T-shaped groove to facilitate the installation and adjustment of workpieces. It is equipped with waterproof cover to effectively prevent the splash of saponification liquid, which is environmentally friendly, beautiful and durable; The fuselage adopts environmental protection closed structure;
  8. The screw barrel is welded from thin-walled seamless steel pipe, with dynamic balance detection and small static and dynamic runout; Chrome plated surface, durable and wear-resistant, not easy to produce scratches;
  9. Variable frequency speed regulation of wire conveying motor, stable operation, low noise, installation of molybdenum wire at low speed, safe and reliable, and wide speed regulation range
  10. No transformer, no power resistance, no cooling fan, fully enclosed structure, greatly reducing noise, equipment noise ≤ 70dB, and no heat is emitted; Therefore, it can keep clean and not easy to damage than other electrical appliances.
  11. The high-frequency circuit adopts high-performance digital pulse power supply and patented high-frequency constant current source technology, which has the function of limiting peak current and short-circuit current, reducing the probability of wire breakage. In the cutting process, it has the function of Closed-loop Detection and control, that is, detecting the discharge state and dynamically adjusting the discharge gap to make the cutting stable, especially in the cutting of large thickness materials, this stability and reliability is more obvious;
  12. Non resistance constant current drive, low power consumption, energy saving and reliable;
  13. Intuitive, convenient and modifiable parameter library (9 groups in total). Users can flexibly save cutting parameters, straightening and edge collision electrical parameters of different materials, different heights, different speeds and different surface roughness. This design reduces the process requirements of machine tool operators and simplifies and facilitates machine tool operation
