  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.

• Reusable molybdenum wire cut EDM machine is original from China, it is also named as high speed wire cut EDM machine. The basic principle of wire cut EDM is that a thin metal wire, usually molybdenum wire for reusable electrode wire type wire cut EDM, is fed through the workpiece, flushing with cooling fluid, to get needed shape of workpiece. Wire cut EDM is typically used to cut metal workpieces with thickness range from 2mm to 500, more than 500mm for machine models. It can make punches, tools, dies, molds and other precision parts from hard materials that are difficult to machine with other metal processing equipments.
  Adopt multi-time cutting technology at the base of high speed wire cut EDM machine, medium speed wire cut EDM machines are widely accepted by the market in past years, comparing with regular high speed wire cut EDM machine, thanks to multi-time cutting technology, surface finish of medium one is much better, could be around 1μm. There is no need grinding process for parts cut by wire cut EDM machine anymore.
  Kingred’s advanced “C” structure wire cut EDM, high precious linear guideway and ball screw, with multi-time cutting technology, cutting accuracy and surface finish of Kingred’s machine is approaching to Brass wire cut EDM’s much more closer. To some degree, for most of cutting works, Kingred’s wire cut EDM machine is able to replace brass wire cut EDM machine.
  Molybdenum wire cut EDM machines are widely used in mold king, electrics, precious machinery, auto components, army industry and etc.,
