Main Performance Features

Adopts advanced “touch screen (or mouse)” technology, abandoning the traditional cumbersome keyboard operation. Various operations from positioning to processing can be conveniently performed through simple screen operations.

Precision Circuit Board Design

The discharge control board adopts a highly integrated design, integrating the original four boards into one. It has CAN communication function, processes data signals through on-board high-speed single-chip microcomputer and CPLD chip, and adopts mainstream full optocoupler isolation design to greatly improve the anti-interference ability and stability of the system.

It has a user-friendly interface and adopts a conversational mode. Even if the user does not understand NC programs, they can correctly operate the CNC series power supply.

AUTO Processing Function

With AUTO processing (automatic processing), the user only needs to input processing requirements according to the prompts on each module screen. The system will automatically generate NC instructions from rough machining to finish machining, perform automatic processing, and complete with optimal processing time and processing effect.

Expert Processing Technology Database

The system is equipped with a rich process software database and various combination modes of electrodes and workpieces, which can perform automatic and manual processing of various materials. Especially for the processing of some special materials, it provides users with a wide range of choices: such as processing cemented carbide materials, superalloy materials and titanium alloy materials. The power supply is highly targeted, with small processed surface metamorphic layer and little impact on surface hardness (HRC).

Automatic Positioning Function

It has end face positioning, angle positioning, column center positioning, hole center positioning, arbitrary three-point circle center positioning and discharge position alignment positioning functions. At the same time, the automatic positioning function can be used for online measurement and online correction of processed workpieces.

Automatic Arc Clearing Circuit

It real-time monitors the machining gap during EDM. When slight short circuit and arc pulling occur, it alarms and performs arc clearing treatment in a timely manner.

Liquid level control, automatic fire extinguishing device, etc., ensure the safety of machine operation. When the liquid level is lower than the height required for processing, processing will not be performed.

Power Failure Recovery and Contact Sensing Functions

The machine can memorize the coordinate value of the current coordinate system. In case of sudden power failure and other emergencies, it can still find the set coordinate point after restarting. In addition, it has contact sensing, diagnosis and error message prompt functions. When an operation error or fault occurs, there will be an alarm and error message prompt to guide the operator to refer to the manual.

Various Processing Modes

Rich CNC Rocking Functions

When the spindle is in servo motion, the other two axes can be combined into different trajectory rocking motion modes according to the electrode shape to realize medium and fine trimming of the cavity sidewall. The rocking function is matched with the high-speed tool lifting (AJC) function. Its motion promotes chip removal, and stable processing can be achieved without flushing. The powerful Loran function, through the setting of LN and LP parameters, realizes the separate processing of rocking actions in different quadrants and provides different rocking modes.
