1.C structure

High rigidity “C” structure design, adopts high intensity HT250 casting iron as all parts of machine, to make sure long term accuracy and performance. All casting used by Kingred are made by resin sand casting technology to guaranty quality of casting(same casting technology as brass wire cut EDM machine. Two times tempering treatment, to realize permanent mechanical precision.
Advance “C” structure, much stronger than “F” double frames structure. For “F” double frame structure, there is vibration of frames while wire feeding at very high speed, there is no such kind problem for “C” structure
For cutting accuracy, thanks to strong rigidity, “C” structure wire cut EDM acts much better than “F” double frames structure wire cut EDM. Kingred’s “C” structure wire cut EDM machine can do face cutting, i.e. Z axis approach workpiece closely and do cutting.

2.“T” shape machine bed and “+” shape table travel design

“T” shape machine bed, same design as brass wire cut EDM machine, with this unique design, machine bed can bear much more weight than regular rectangular shape design. With “+” shape table movement design, the whole travel of X and Y axis it limited within the area of “T” bed, i.e. the Max travel of X and Y axis move within the range of machine bed, while for “F” double frames structure, the Max travel of X and Y axis is out of range of machine bed, this situation will affect mechanical accuracy of machine.
“T” shape machine bed and “+” shape table travel system make enhance performance of “C” structure wire cut EDM machine, make it acts better than “F” structure wire cut EDM machine again.

3.P3 grade linear guideway and ball screw

Kingred chooses Taiwan built high precision P3 grade linear guideway and ball screw, in order to get good surface finish and cutting accuracy, the stability of X and Y axis motion is very important, different from old steel roller guideway, linear guideway and ball screw ensure motion of X and Y axis much more smoothly and stably. High rigidity designed machine parts, adding with high quality motion components, cutting performance of Kingred’s machine tops in the market.Linear guidway has longer life o than normal V guideway.

4.Double-ways wire tension control system

As the molybdenum wire of wire cut EDM machine is reusable, so wire will get loose at long time use due to drawing force. Kingred’s double-way wire tension control system will be keeping tightening wire all the time. Tension control system is consisted by heavy drop, linear guideway and guide.

5.Taper cutting system

Taper cutting system is fixed under Z axis travel, thanks for high rigidity of column of Z axis, taper cutting system perform perfectly, U and V axes are driven by stepper motor, and work with X and Y axes to release 4 axes move simultaneously.

6.Working table and clamping system

Larger and stronger working table without T groove, Kingred purchased highly accurate surface grinding machine to machine working table and clamping of our wire cut EDM machine. Kingred use high accuracy clamping system which is special for brass wire cut EDM machine, it is easy to fix various shapes workpiece.

7.Wire drum seat

Kingred adopts high precision linear guideway as movement components of wire drum seat, smooth travel of wire drum make sure wire travel more smoothly. Whole travel of wire drum is within range of seat, higher rigidity.
High quality light steel as material of wire drum, smooth movement, resisting corrosion, imported inverter to speed of wire drum tuning and direction changing to get better cutting accuracy and surface finish of workpiece, and reduce wire broken at the same time.
Slide cover of wire drum, easy to handle, much more humanized.

8.Z axis

Standard Z axis motor drive up and down, there is no extra charge.
Thanks to high rigidity Z axis travel(square steel guideway design), Kingred’s wire cut EDM has very good accuracy of Z axis travel. Different from “F” double frames wire cut EDM machine, when move Z axis, for “F” structure, the whole upper frame move up down, the movement of big upper frame is parallel to working table and pretty long, the movement of upper frame will affect accuracy. But for “C” structure, there is no such kind problem, as Z axis of “C” structure wire cut EDM is vertical to working table, with our high rigidity Z axis design, the accuracy of Z axis travel of Kingred’s machine is very good.

9.Automatic lubricating system

Standard automatic lubricating system for all moving components of Kingred’s wire cut EDM machine, it makes maintenance much more easy and convenient, the automatic lubricator will do lubricating each 6 hours, customer just need to fill more lubricating oil before it runs out.

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.

14. Support linear scale and closed- type with servo motors to increasing positioning accuracy of machine.

	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.
