CNC EDM M Series

High Precision Heavy Duty EDM


Each aspect of machine must be engineered to be extremely durable and exactingly precise.

[Tool - Finite Element Structure Analysis]

It is formed by Meehanite cast iron, and therefore is durable & stable. Using CAD/CAE finite element to analyze & design could achieves high rigidity cellular bed to be undistorted. Moreover, integrated column, shortest structure design, & fully-obstructed square main shaft moving block could endure large lateral thrust, and hold heavy electrodes extremely steady. With practically perfect hairline, straightness & perpendicularity, even if it is in the end of travel, and only has a very little drooping oscillation. Equipped with automatic lubrication device & oil cooling machine could control the temperature, and stabilize mold's machining precision.

[New Power Supply & Control System]

The newly designed power supply control system provides realtime and stable energy control, which is not affected by the environmental fluctuation. Unique discharge detection in combination with high resolution movement control dramatically increases fine finishing speed. Avoids surface hole erosion and creates extra fine surface.

[ Power - Less Than 0.05% Super-Low Wear Circuit ]

The advanced digitized power technology control the production of every electrical current and adopt equal energy's discharge circuit design to make after-finework polishing very easy. Now, electrode wear ratio referring to SL circuit below 0.05% from thick to thin only need a electrode to complete high precision work. Cleaner machining in corners, rising points, channels, ribs, and sharp angles contribute to a very low electrode wear. Specially providing 2mm ~ 5mm small piece and small clearance discharge conditions will be most suitable for Electron Information Precision Mold Industry to work with particular low wear. A modern Fuzzy intelligent control system provides the auto adjustments of machining parameters and improve the machining efficiency and safety. More easy to use, a beginner can operate like an expert.

[HQSP The High Quality Super Polishing Equipment](optional)(Taiwan invention patent: I229622)

HQSP is able to substantially increase luster Surface Area Limitation to approximately 400cm². The time for completion of luster surface area is approximately 1/2-1/5 longer, to reduce the machining surface cracking and saves time and efforts in manual polishing operations after machining.

[Windows interface](optional)
  1. More user friendly graphical interface improves the user familiarity with the system also reduces the time of learning.
  2. Diversification measurement function (3 points for Center, unsymmetrical groove unsymmetrical column, parallel calibration)
  3. Multi-workpiece automatic measurement with the same size, the coordinates can be recorded for the convenience of program editing.
  4. Programmable measurement, the measurement function can be edited into program, for the needs of automation operation.
  5. Program check, alert the user program errors and the cause.
  6. Remote monitoring by mobile phones, pads, or laptops anytime anywhere.
  7. Remote program editing on laptops anywhere.
  8. Remote warning reminder can be sent to designated email address.
  9. Compatible with EROWA calibration equipments.
  10. Compatible with any coordinate measuring machine(CMM) electrode compensation files.
