Wire EDM KD400ZL

Wire EDM KD400ZL

KD400ZL is latest product that designed and produced by KINGRED, it’s most advanced machine ever made in the filed of molybdenum wire EDM in China

KD400ZL is featured in below: 1. Integrated sheet metal(invention patent), nice appearance and space saving, easy to operate. Optimized electrical wiring system to reduce malfunction ratio; 2 patented wire feed structure, wire drum is fixed with separated wire drum motor, and this design solved the problem of vibration due to motion of wire drum, to make cutting more smoothly, then get better surface finish and accuracy;3.vertical structure of taper, we adopt vertical structure of angle cutting system(invention patent) with high precise linear guideway and ball screw; 4. We adopt linear motor for ZL series, Linear shaft motor uses magnetic principle, the stator drive rotor to move, but there is no physical contact between. The benefit of linear shaft motor: It eliminates ball screw drives, no ball screw of the machine with linear shaft motor, as you know, there will be wear of ball screw after years of use. Besides, there is also problem of gap when screw change direction, so accuracy of ball screw machine will get worse after years of use. Better positioning accuracy and long term accuracy keeping.

  • ZL structure

    Structure features

    (1).High intensity HT250 resin sand casting;
    (2).Twice tempering treatment, to remove inner stress and keep long term accuracy;
    (3).High rigidity "C" structure, it doesn't have upper frame, so there is no problem of deformation of upper frame, stronger than conventional "F" structure;
    (4)."T" shape machine bed, "+" shape carriages design, X and Y axis moves always in range of machine bed, no effect of gravity.


    Big angle cutting system

    (1) Kingred adopts vertical structure for angle cutting system(invention patent), U&V axis is driven by high precision ball screw and linear guideway to realize big angle cutting ±15°;
    (2) Hand control box to control U and V axis to perform up and down motion;
    (3) Z axis can approach workpiece closely to do face machining to get better cutting performance;
    (4) Z axis is driven by low speed high torque motor, there is no need to remove wire when adjust Z axis, it's convenient for cutting of different heights.

    Linear Motor

    Linear Motor

    Latest linear motor combines with linear scale to realize fully closed-loop control,advanced performance,precise control,bar type linear motor with control resolution 1um.
    Non-touched type transmission,high cutting speed with good stability.
    High sensitive servo control to make sure gap control of electrical discharging much more stable,and increase cutting speed 8-15%.Super low resistance brings high efficiency and repeat accuracy,no gap compensation of screw,low wear,and longer use-life.

  • Structure of AutoCUT

    As show in above figure, AutuCUT is a whole integrated solution for wire cut EDM machining. AutoCUT system is consisted by AutoCUT software, PCI based drive card, and high stabile main board of stepper motor drive, and 0.5 microseconds medium speed wire cut EDM high frequency main vibration board. AutoCUT software includes AutoCAD embedded module and cutting control software.

    Main function of AutoCUT:

    1. Support graph drive automatic programming, there is no need for customers to touch codes, only need to set cutting technology to the graph for cutting; at the same time, it support 3B or G code list created by other wire cut EDM software, and simply read and process to do cutting.

    2. Software is embedded in AutoCAD, CAXA and some other software, customers just need to know AutoCAD or other design software, easy to use and no need for special training of drawing.

    3. Several machining pattern combined together in cutting(continuous, single segment, forward, backward, trace back and so on.).

    4. XYUV four axes direction change is adjustable, drive motor could be set as 5 phase 10 beats or 3 phase 5 beats and so on.

    5. Real time monitoring upon X, Y, U.V and cutting situation.

    6. Machining preview, real time display of cutting process; 3D display and tracking of taper machining, zoom in and zoom out to view graph, front view, right view, top view and etc..

    7. Capability of multi-time cutting with customer maintained data base of cutting parameters, make multi-time cutting much more easy and reliable.

    8. Taping cutting adopts 4 axes simultaneous technology, can process up and down different shape cutting convenient.

    9. Control board to drive 4 axes movement, work stably and reliably.

    10. Support several cards work together in parallel , several wire cut EDM machine could be controlled by only one computer and do cutting at the same time.

    11. With automatic alarm function, it will alarm when cutting is done or malfunction happens, time of alarming is settable.

    12. Support angle clear time-delay, time delay when cutting angle of track, to make avoid impact of deviation caused by molybdenum wire.

    13. Support compensation of teeth gap of screw to increase mechanical accuracy.

  • wire cut edm sample 1 WEDM take wire (Molybdenum wire or Tungsten and Molybdenum alloy wire ) as electrode, working liquid as media, Electrical discharging happened between the electrode and the work piece by using of the high frequency impulse power and the high peak current to bring high heat and high energy to erode the work piece. The preconceived track of the wire is controlled by the moving of X-Y axis and U-Y axis which are driven by the machine. Then the work piece is processed.
