ZNC Die Sinking EDM Machine

CNC Die Sinking EDM Machine, also known as CNC EDM die sinking and CNC Spark Erosion Machine provided by one of the professional CNC EDM machine suppliers, DMNC, is a kind EDM machine that utilizes high-frequency power between positive and negative anodes (electrode and workpiece), 3-axis or more axes controlled, to break through the gap between electrode and workpiece, to create high temperature to melt and remove metal to get needed profile cavity. It's like a projective copy of the profile of the electrode on the workpiece.

ZNC electrical discharge machining machine is the traditional type with X and Y axis manual control, usually operator needs to manually move the working table to the location of where to do spark eroding on the workpiece. Z axis is automatically controlled by servo motor, die sinking operation of ZNC EDM machine is simple compared to CNC EDM die sinking. Due to the limitation of no control of X and Y axis, ZNC EDM machine can't do simultaneous orbital machining, even use an orbital cutting head, the result of accuracy and surface is not as good as what can achieve on CNC EDM machines. But thinking about the cost of ZNC EDM, it's ideal for the start or jobs without a strict requirement of accuracy and surface finish.

ZNC Die Sinking EDM Machine Highlights

Original Taiwan C-Tek controller, LCD monitor, Industrial Computer Controller.

High accuracy X, Y, Z three axes C3 grade Taiwan made ball screw.

Z axis imported Japanese Sanyo servo motor control.

Three axes DROs of 0.005mm resolution.

Resin sand casting as machine body and inner stress removed to make sure long-time rigidity and stability.

Z axis is equipped with a high precision roller guideway with a Japanese SANYO DC servo motor, to make the movement of Z axis more sensitive and smoother.

The machine has a wide machine base to make sure the machine is strong enough for heavy loading, X. and Y axis have V shape and flat guideway with FEFLON wear-resisting sticker, movement of heavy load is smooth and light, with no crawling phenomenon.

Working lamp, fire extinguisher and lubrication unit, and patented electrode holder are all Taiwan made.

ZNC Die Sinking EDM Machine Function Characteristic Introduction of Control System

More than 20,000 units of programming storage capacity. Normally, more than 20,000 different programmings of mold or customer numbering can be stored

With a mirror surface processing circuit, a true mirror effect can be performed. Furthermore, it is even better to use orbital processing and powder mixing processing.

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 workpiece 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 a rough→moderate→fine.

X, Y, Z-axis coordinate are switch with Metric and English system

If machining is unstable, the 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.

Auto arcing detecting function, if unsteady caused by arcing occurs, the computer will adjust machining parameters and rise to jump up height, then the normal condition would return.

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.

The function of avoiding second discharging and carbon deposition rapid raising or discharging boundary searching rapid rising.

Power control (equal energy) function for homogenizing machining effect. And this function could be switched off to accelerating graphite electrode machining.

Generator new design conforms to a power supply box and 15-inch LCD display criterion of European CE safety regulation, which is dustproof, waterproof, electric noise-proof and circuit board life could also be raised.

Industrial class PC-based controller is applied, and the traditional hard disk is substituted by new DOM type memory, which enables faster and more steadily speeds of file reading and it is more suitable for industry application.

Up discharging (reverse machining) function makes special machining easier.

Two independent machining coordinates. The male die and female die could be parted or machined in different coordinates.

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

Two jumps up to speed type, which serve speed could be raised when no electrode deformation and big area machining efficiency could also be raised.

Separately storage of coordinate and machining data and same machining condition could be rapidly added in different part machining.

Two high voltage circuits could be set in partial voltage or partial current according to the customer's need

Arcing detection setting function could start the carbon deposition hardware detecting circuit, and every charging pulse could be detected and the current will be cut off when an abnormal pulse occurs. So no short circuit is caused by a short circuit

Discharging high voltage pulse control, which enables the settings of different high voltage pulse types and it could go with machining speed and electrode wear.

We also provide EDM die sinker machine, DIE sink EDM machine, ZNZ machine and so on.And now the ZNC EDM machine price is very reasonable.
