Wire EDM KD500GL

Early in 2013, Kingred launched new designed EDM Wire Cut KD500GL, thanks to new design of taper cutting system-unique design of U,V axes carriages with excellent rigidity make KD500GL different from others in the market. For old type machines, customer needs to remove molybdenum wire when he wants to adjust height of Z axis, but for KD500GL, customer doesn’t have to, just simply push buttons to move Z axis upward and downward, much convenient for operator and save a lot of time to thread the wire again. All X,Y,U,V axes Taiwan made linear guideway , and X,Y axes are equipped with servo motor. All these design lead to leading performance in getting good surface finish of cut parts.

EDM wire cut KD500GL has X,Y axes travel 400×500mm, it could cut all kind of conductive material such as steel, alloy, copper, titanium alloy and etc. Kingred’s GL series wire EDMs are equipped with hand control box to control movement of X,Y,U,V axes. Swift feed of X, Y axes with servo motors, stable cutting accuracy in all time. “T” shape machine bed with 6 support points to make sure rigidity of whole machine; Cross design X,Y axes carriages always move within range of “T” machine, and won’t exceed range of machine bed to its end, this design can get rid of gravity of X, Y carriages when they move to ends; “C” structure column design, machine head is installed in vertical direction, different from old “F” structure wire cut EDM, wire frame is in horizontal direction, there will be problem of swing of wire frame during wire feeding, on the contrary, for “C” structure, wire frame is in vertical direction, no problem of wire swing during wire feeding. All these different designs of KD500GL make it unique in the market of molybdenum wire cut EDM and performance is leading in the industry.

  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.

  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.

• 	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.
  "Kingred" machines featured with beautiful shape, novel structure, superior performance, and convenient operation. Meanwhile they are of good rigidity, small cutting force , big load bearing, steady movement, and safety operation. they are suit to cut the workpiece of high precision, fairly good rigidity, high toughness, especially the cold die, extrusion die, plastic mould, gear cutter hob, precision component (including big taper, same taper, unequal cone, laid abnormity and etc.)
  Medium speed wire cut EDM is a new generation of EDM machines which are widely used in the fields of moulds, automobile parts, aeronautics and astronautics, electronic instrument, military, light industry, and household appliances.
