Application

CNC Die Sinking/Sinker EDM Machine, also known as CNC die-sinking EDM electrical discharge machine and CNC Spark Erosion Machine provided, It is a kind EDM spark erosion 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. The product made by CNC EDM die sinker/sinking sparkling machine is like a projective copy of the profile of the electrode on the workpiece. CNC EDM die sinking machine is widely used in mold making workshop for the processing of complex mold cavity and curved surface of molds,precision machinery parts , especially complex curved surfaces which are inconvenient for polishing, which can save the manual polishing process, improve the service performance of parts, and has very important practical significance for shortening the mold manufacturing cycle.

Windows Platform CNC EDM system function explanation

Ø LCD, touch screen input. 

Ø Windows platform CNC control system, help for every page, quick and easy to learn and use.

Ø Multiple pages to be edit at the same time, automatic generate machining program with multiple cavities.

Ø Machining speed is about 30% faster than DOS platform discharging control system.

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

Ø Optimized high-frequency power control system，most efficient control circuits.

Ø 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. Min machining current 0.1A，Best surface finish Ra≤0.1µm.

Ø 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.

Ø AUTO machining function:Input material of electrode and workpiece, machining area, shrinkage of electrode, required surface finish and etc Then control system automatically calculate machining parameters from rough machining to finish machining according to expert database.

Ø 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.

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

Ø 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.

Ø Safety control function:Overload protection, code grammar detecting, oil level control, oil temperature control, automatic fire extinguisher.

Ø Power-off recovery function:The system can remember the present position of coordinate, when suddenly power-off happens, the present position can be kept.

Mechanical Features

Ø Adopting precision CAD design and high precision frame structure.

Ø Machine Body is resin sand, non reniun force advanced casting, Adopt HT300 ageing treatment casting, keep precision long time. Structure is reasonable, no deformation, rigid, durable, precision remains unchanged.

Ø The working table is made of high-class marble(00 grade), barely any deformation due to a change of temperature.

Ø The column adopts a one-piece structure,which makes the B-axis more rigid,and the heavy-duty electrode processing can be done easily.
