CNC Die Sinking EDM Machine, also known as CNC EDM die sinking and CNC Spark Erosion Machine provided by one of the professional CNC machine milling 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.

Main Functions of KCUT-Kingred CNC Wire Cut EDM Control System

It supports graph-based automatic programming, the operator does not need to know programming codes, in practical operation, the operator needs to load DXF file created by other software then post the process in KCUT to create a cutting track according to instructions in the software.

Multiple machining modes, flexible for different purposes, for example, single segment cutting, continuous cutting, forward cutting and backward cutting.  

XYUVZ can realize 5-axis simultaneous control, drive type could be stepping drive or servo drive, all 5 axes can be monitored in real-time in the main interface of cutting.  

KCUT shows present machining position, coordinate, finished percent of the task and left time to go in real-time. The operator can judge actual cutting status according to information in GUI, which could be zoomed according to the operator.   

Standard taper control system to realize cutting of equal-degrees taper, variable-degrees taper and abnormity (up-down different profile taper). Multiple axes simultaneous control makes complicated taper cutting much easier and efficient.  

Standard with multiple cuts capacity to get a better surface finish and cut accuracy.

With a capacity of corner clearing to improve performance of corner-cutting.

Support compensation of screw pitch, capable of segmental compensation of pitch error of the machine.

With automatic alarm function, when machining is done or malfunction appears (such as short circuit), a dialogue of alarm pops out and KCUT records information of alarm automatically.

Remote control for the motion of the machine, wire feed, pump, HF power, etc., which makes operation more efficient.  

Remote has tool setting function (wire straightness setting) to simplify straightness of wire to the workpiece, easy to switch parameters for tool setting.

Power off recovery function, repositioning start point, pause point, endpoint, moving track selection function.

Cutting program setting includes jump holes setting, mirror, rotation, lead-in line setting and so on.

Short circuit detection & feed-back, short circuit alarm. When a short circuit happens, the wire would move back and feed-forward again to get a suitable gap between the wire and the workpiece.

The manual function includes move axis, centering, touch edge, etc.

Setting includes factory default setting, user setting. The factory default setting is not allowed to change unless permission and guidance from the manufacturer.

IO monitoring could keep monitoring data of input and output and to enable operator know control system better.

The Debugging system records information about alarms.

File management could do a set of graphs in the system, it also can read files from the hard driver or USB memory, the file should be DXF.

length measure function to check the distance between two points, to make sure the graph is correct.

Simulation function simulates the actual procedure of cutting, to check if programming is correct.
