GW735P CNC EDM Machine

Description
GW735P CNC EDM machine is suitable for machining small-middle size of dies and other parts. Its host is separated with the electrical cabinet. Machining tool consists of mechanical bed, pulse power, control system, etc.
EDM machine is a machining device that to eroding the material in a certain liquid medium based on the electric erosion phenomena of the pulse discharge working on the conductor. To make the work piece meet the technical requirements of its shape, size and the surface finish quality after machining.

Application
Electric discharge machinery is widely used in the fields of mould production for electronic component, automation, information and communication technology, household appliances. And it also plays an important role in facilitating the parts’ production in aerospace industry, automobile industry, dental industry, and watch and jewelry industry and many other fields.

Part of CNC EDM Machine
The electrical discharging power is divided into host computer and power pulse control system.
1. Host computer is the core of the whole system, which is responsible for running the exporter system and monitoring the whole system. This part is based on the new type of embedded industrial process control computer (IPC), which is stable and reliable. It can be upgraded following the advancing of the electronic industry.
2. Power pulse control system is in charge of generating and adapting the pulse energy, which takes Adaptive Control Algorithm to ensure the purity of electrical pulse. This part is composed with micro-controller, programmable logic devices, power devices and other devices.


Structure of the whole system includes:
1. IPC (human-computer interaction, expert process database)
2. Servo motor and driver(drive the spindle do servo motion, control the discharge gap)
3. MCU unit (generate, detect and monitor the wave of electrical pulse)
4. power amplifier (output the electric energy for processing).

Advantages of CNC EDM Machine
1. The system has rich expert technology database and processing strategies.
2. Real time display of processing parameters and status.
3. The expert processing system can generate entire processing parameters from rough to finishing machining according the user’s preference to machining accuracy or speed.
4. Discharge sensitivity setting: The adaptive control algorithm can implement adaptive adjustment to the discharge state, to reduce the abnormal discharge and improve the quality of processing.
5. The system can handle multistage complex processing. The finishing condition of processing can be set as timing machining or machining as a given depth.

Technical Characteristic
1. Simple and friendly system interface helps to operate more accessibility.
2. Oriented programming based on the expert system is easy to handle, Keeping the user free of professional knowledge.
3. Real-time status display, intelligently monitoring the discharging progress according user’s setting.
4. Using isopulse power supply technology, the electric discharge machinery can control every discharge pulse power precisely, with advanced spark monitoring system.
5. Control and detection every discharge spark, especially suitable for machining fine and complex structure parts.
6. Energy-saving and environment-friendly are achieved by replacing current-limiting resistance with power inductor, meet the trend of green technology.
7. Standard module design is convenient for expanding energy.
8. Unique pulse character has outstanding performance on processing cemented carbide.
