The brand-new DK series large-scale（size from 1000 to 4000mm） CNC wire cutting EDM adopts AC servo control, which achieve unprecedented processing capabilities. You'll no longer be limited by the weight and size of workpieces. Powerful R&D team can also make special design for special customer's requirement.

Structural description

Ø The Y-axis is placed behind the X-axis in a T-shaped table layout, improving accessibility throughout the table surface. The separate bed frame is made of rigid hard connections to ensure that the YX axis right angle plate remains unchanged permanently. With a large travel（1200*1600mm to 2000*4000mm） and height (600/1000/1300 optional), it comes with a ladder step, and the bed frame sheet metal design has a step area for easy operation.

The Machine Body

Ø Which ensures that the machine can withstand a maximum weight of more than 5 tons, and the T-shaped bed frame table, column, and other critical castings are made using high-strength resin sand casting technology, two aging treatment to eliminate stress and effectively inhibit the deformation of the machine tool. with the entire design made into a large, thick-walled box-type casting. The bed frame interior is designed with several vertical dividing ribs that run from top to bottom, providing the bed frame enough rigidity and strength!It has super-large load capacity.

Guideway and Ball Screw

Ø Adopt Taiwan imported high-load extended tension linear guideway and P3 grade double nut ball screw , which can ensure the continuous processing of heavy parts and large molds weighing up to more than 5 tons. It can complete the base cutting of 3D metal printed parts in one setup.

Driving motor

Ø XY-axis uses high-power AC servo motors driven by coupling joints to achieve frictionless transmission with the screw, effectively improving transmission accuracy and eliminating reverse errors. At the same time, it adds a lower arm anti-collision function to prevent damage to the machine tool due to technical reasons such as accidental operation.

Structure of wire frame

Ø The symmetric structure for the upper and down frame to keep the tension of moly wire within the scope of normal tension. So no matter thin or thick work piece, the moly wire is not easy to break down.

The wire winding and traveling system

Ø Wire winding drum is made of special steel, which is more stable, anti-corrosion. converter control the running direction, Which can be used longer time, improve the precision, roughness and reduce the wire broken.

The Taper Cutting Mechanism

Ø It's driven by two step-motors to realize U and V movement, which can make the 4 axis (X,Y,U,V) simultaneously movement.

The working table

Ø The table is equipped with a movable modular clamping device that can be moved to multiple positions to achieve installation and clamping according to the actual situation of the workpiece.

Working area

Ø The frame water retaining structure with a three-sided opening design can against splashing and dripping of cutting fluid,allows for unobstructed operation and loading/unloading of workpieces.

Lubrication system

Ø Uses an automatic lubrication device and a multi-point quantitative distributor to ensure that every automatic lubrication can deliver sufficient lubricating oil to the lubrication point.

Working fluid tank

Ø The 200L large-capacity multi-stage filtration coolant tank can effectively reduce the temperature rise of the coolant; it provides a guarantee for preventing large parts from expanding due to prolonged EDM processing.

Control system  

Ø Which integrates the program and control and based on Windows. This new designed Autocut software is the unique software for WEDM running on the condition of windows. It is use graphic drive technology and auto-program, user doesn’t need to contact the code, only need to set the processing technics for the graphic. meanwhile,support 3B and G code generated by other WEDM software.upgrade the efficiency of working, reduce the mistakes.

Ø Using the PCI slot controller card and the High-tech Industrial computer, which greatly enhanced the stability of control and greatly reduced the computer the failure rate.

Ø To achieve a fast and convenient computer communication network, through network technology, graphics, data and program transmission, can be directly controlled by the technical design department since the first establishment of a program.

Ø Embedded Control system can be smoothly connected with many design software such as AUTOCAD & etc. Fulfill integration of CAD/CAM.

Ø Adopt 4 axes linkage control technic to process taper workpiece. Process the top and bottom shaped taper conveniently, make the complicated processing easy and exactly.Process track with 3D designed.

Ø XY axis the drive motor be set at AC servo motor. The search function of mechanical origin enable the transmission screw pitch compensation, in order to greatly improve the positioning accuracy.

Ø With a large storage capacity database, which accumulated from many experiences. User can choose the suitable parameter according to deferent working conditions. Users can adjust machining parameters to establish a database at any time according to their own experience.

Ø Pulse power of the control parameters directly from the software to control and improve the ability of pulsed power output of the interference, thereby increasing the roughness of workpiece, reducing the loss of molybdenum wire, you can choose a variety of pulse waveforms for a variety of processing conditions, improve the cutting ability of the workpiece.

Ø Simplifies the operation buttons on the control panel, a large number of button functions directly controlled by software to achieve.
