Sinker EDM ZNC450

EDM machining is electrode and workpiece are submerged into electrolytic working fluid, and respectively connected to cathode and anode of HF power source. When electrode approach to workpiece to a tiny and certain distance, electrical discharging happens, at the same time, high temperature erase release super high heat to erode workpiece.

Kingred’s EDM Sinker Machining ZNC450 is featured in strong function, convenience and reliable operation; Machine is designed according to analyses of resistance to draw, resistance to press and reaction by computer. Casting is used FC-35 by national weathering and all kinds of treatment, it wears well and its precision is changeless. Machine structure is reasonable without distortion, of good rigidity to insure process precision. Rails are “V” shape, can move lightly under heavy load and good precision Z axis is used Japanese “SANYO” DC servo motor. High precision bears, the working table are used rails with “TAFULO” face. Danish “GRUNDFOS” oil pump or Italy “GALPEDA” oil pump. Three axes SINO grating ruler. Can arbitrarily choose the methods of removing scrap iron, sweeping oil or sucking oil, also choose process that the work piece is not submerged in oil. It suits to process cavity, holes and special shape parts in copper, steel.. Lubricating system is used callback way, lubrication of rail is completed once, and retains cleanness of appearance.PCB boards is moisture proof, anticorrosive, gold-filled.

More than 20,000 units of programming storage capacity. Normally, more than 20,000 different programmings of mold or customer numbering can be stored 2. With mirror surface processing circuit, a true mirror effect can be performed. Furthermore, it is even better to use orbital processing and powder mixing processing. 3.10 segments auto editing function. ① Manual edit: edit machining condition by experience. ②AUTO Z auto edit: Max. Depths, initial current and finished process, machining area selection are provided, and then machining condition edit can be finished automatically. ③ Intelligent condition edit: electrode shape, electrode and workpeice material, workpiece section area and finished precision selection, depth setting area are provided, and then machining condition can be complete at a time by the way of rough→moderate→fine. 4. X,Y,Z axis coordinate are switch with Metric and English system 5.If machining is unstable, discharging condition is auto adjusted by modifying discharging efficiency and working time. After that, the condition will restore automatically. And it is also adjustable at any time. 6.Auto arcing detecting function, if unsteady caused by arcing occurs, computer will adjust machining parameters and rise jump up height, then normal condition would return. 7.If could set that after 2~10 times discharging(jumping up control), the electrode will be raised(safe height Z) to the set arbitrary position and continue machining. This could achieve good slagging off performance for deep hole machining. 8.Function of avoiding second discharging and carbon desposition rapid raising or discharging boundary searching rapid rising. 9.Power control(equal energy) function for homogenizing machining effect. And this function could be switched off to accelerating graphite electrode machining. 10.Generator new design conforms to power supply box and 15 inch LCD display criterion of European CE safety regulation, which it is dustproof, waterproof, electric noise-proof and circuit board life could also be raised. 11.Industrial class PC-based controller is applied and traditional hard disk is substituted by new DOM type memory, which enables faster and more steadily speed of file reading and it is more suitable for industry application. 12.Up discharging(reverse machining) function makes special machining easier. 13.Two independent machining coordinates. The male die and female die could be parted or machined in different coordinates. 14. After power off, system restarts and automatically reloads previous machining condition and coordinate of last time, so discharging could be finished by pushing remote control box without panel operation 15.Two jump up speed type, which serve speed could be raised when no electrode deformation and big area machining efficiency could also be raised. 16.Separately storage of coordinate and machining data, and same machining condition could be rapid added in different part machining. 17.Two high voltage circuits could be set in partial voltage or partial current according to customer’s need 18.Arcing detection setting function could start carbon deposition hardware detecting circuit, and every charging pulse could be detected and current will be cut off when abnormal pulse occurs. So no short circuit is caused by shoot circuit 19.Discharging high voltage pulse control, which enables the settings of different high voltage pulse type and it could go with machining speed and electrode wear.
