We provide machine sales, models are: DK-320T、DK-400T、DK-500T、DK-630T, welcome to contact us.
In dk-t series, the traditional concept is overturned by wire feeding, and the design concept of slow wire walking is used for reference. The fuselage structure is redesigned: the traditional "bar" type is changed to "product" type, so that a relatively long shaft is completely attached to the machine bed, which solves the problems of unstable center of gravity, poor positioning accuracy, especially the consistency of extreme machining parts! Dk-t series of wire feeding is not only the improvement of design concept, but also the materials used are carefully selected: the bed material is gray cast iron HT250, twice tempered!
Complete set of imported HIWIN ball screw and linear guideway!
The X / Y axis adopts Panasonic AC servo motor of Japan and the screw rod is directly connected through a special coupling, without transmission clearance, meeting the requirements of high-precision machining
Our products adopt U / V axis carriage to directly install high precision linear guide and ball screw (instead of traditional roller inlaid steel guide rail plus ordinary thread screw or pseudo linear guide and screw combination)! UV motor also uses subdivision motor, completely changing other manufacturers using the same control system. When using stepping motor, the program must change the idle speed and axis moving speed to ensure that the motor does not lose step!
The commonly used fixing method of screw rod in the market is one point fixed, one point sliding type! After long-term operation, the screw will swing, wear quickly, and the screw cylinder will run unstable! Our company adopts two-point fixed and one-point sliding installation, which increases the difficulty of installation, but ensures the stability of screw rod and drum for a long time.
In dk-t series, the wire feeder head automatically rises and descends with one key, so that the master will not have to worry about changing materials of different thickness
Loosen 2-4 screws, and need to use the rocker handle to manually turn the screw rod to achieve the head up and down)!
Ordinary wire cutting machine tools, master in order to ensure the cutting effect, have to frequent manual tightening wire! If the master's operating experience is not enough, frequent wire tightening will cause the electrode wire to be tight and loose at the same time (unilateral elastic wire), which makes the cutting effect difficult to improve! Constant tension structure replaces the need of frequent manual wire tightening by the master, greatly reducing the requirements for the operator and ensuring the cutting effect! All guide wheels are made of gem guide wheel, so as to prolong the service life!
The linear slide type wire conveying reversing induction block makes it easier and more convenient for the master to adjust the reversing position! Reduce the waste of electrode wire in the reversing part due to the difficulty in adjusting the reversing block!
Dk-t series of silk walking imitates the working table of slow walking, so that the master can place materials as he likes! And material selection
Quenching ductile iron, no deformation, no cracking!
Automatic oiling system: time-sharing and segmented oiling to protect the moving parts of the machine tool, so as to prolong the service life of the machine tool!
Two pumps in the middle of the water tank, one pump is responsible for processing water, the other is responsible for dirty liquid filtration.

The high frequency power supply increases the step wave, the pulse waveform shape is more accurate, and the processing efficiency is higher.
Numerical control system
Autocut wire cutting programming and control system (hereinafter referred to as autocut system) is a WEDM programming and control system based on Windows XP platform. The autocut system consists of system software (CAD software and control software) running under windows, 4-axis motion control card based on PCI bus, high reliability and energy-saving stepping motor driving main board (without fan), 0.5 microsecond high-frequency main vibration plate and sample taking. Users use CAD software to draw processing graphics according to the processing drawings, process CAD drawings by WEDM, generate 2D or 3D data of WEDM, and process parts; in the process of processing, the system can intelligently control the processing speed and processing parameters, and complete the processing control of different processing requirements. This graphic processing method is an organic combination of CAD and cam systems in the field of WEDM.
The system has the functions of adaptive control of cutting speed, real-time display of cutting process and machining preview. At the same time, it provides perfect protection for all kinds of faults (power failure, crash, etc.) to prevent workpiece scrapping.
Autocut wire cutting control software, friendly interface, very simple to use, ordinary workers can learn to use within 10 minutes to 2 hours. Users do not need to contact with complex processing code, only need to draw processing graphics in CAD software, generate the corresponding machining path, and then they can start machining parts. The main interface is shown in the following figure:
