CNC EDM Sinker Machine C Structure A30, A45 Function Configuration of Controller


Function explanation


LCD, touch screen input CNC EDM die sinking


Simultaneous three-axis control(optional 4-axis simultaneous control)


Super finish PIKA machining circuits-mirror surface machining function; fine current control circuits with better performance of large-area super finish machining, at the same time, the excellent performance of corner clearing


Expert machining parameters database: with high explosive power circuit, especially good for processing hard ally material)

Automatic and manual machining according to a different combination of a different material of electrode and workpiece: copper/steel, graphite 1/steel, graphite 2/steel, silver-tungsten/steel, copper-tungsten/steel, silver-tungsten/hard alloy, copper/zinc alloy, graphite/zinc alloy, copper/copper alloy.


AUTO machining function:

Input material of electrode and workpiece, machining area, shrinkage of the electrode, required surface finish and etc Then control system automatically calculates machining parameters from rough machining to finish machining according to the expert database.


Automatic positioning function:

End face positioning, cylinder center positioning, corner positioning, inner hole positioning, random three points positioning, discharging position self-decided positioning and etc.


Online measuring function:

Utilize automatic positioning function to do the online measuring and amending to the machined workpiece.


Automatic arcing removing circuit:

Real-time monitoring on the discharging status, if any tiny short circuit or arcing happens, the system would remove arcing and give the alarm


Safety control function:

Overload protection, code grammar detecting, oil level control, oil temperature control, automatic fire extinguisher


Power-off recovery function:

The system can remember the present position of coordinate, when suddenly power-off happens, the present position can be kept.
