Universal (Copying) Die-Sinking EDMs
The first electric discharge machines (EDMs), which later in some countries later mistakenly electroerosion or erosion, were sinking type EDMs and worked only with servo movements along the Z axis.
In fact, these were copying EDMs that machined with spark discharges along Z-axis to obtain on the part an inverse mirror-like shape of the electrode. Manual XY movements are used in such machines only to position the part relative to the electrode.
Modern EDM copiers are equipped with a very advanced CNC system that allows you to program many processing parameters or choose machining conditions from those already available in CNC.
ED-ZNC Series
ED-ZNC series – is one of the most advanced machines of its class on the market.
ED-ZNC allow you to solve many machining problems in tool, repair, auxiliary and other industries on a budget.
When it comes to single tasks or small batches, ED-ZNC is the most economical and efficient solution for you!
Die-Sinking Copying Type ZNC EDMs
ED30Z: Z travel (program) = 200 mm, XY travel (manual) = 300×200 mm.
Workpiece up to 550 kg.
ED40Z: Z travel (program) = 180 мм, XY travel (manual) = 400×300 mm.
Workpiece up to 700 kg.
ED50Z: Z travel (program) = 200 мм. XY travel (manual) = 500×400 mm.
Workpiece up to 1350 kg.
ED70Z: Z travel (program) = 250 мм, XY travel (manual) = 700×550 mm.
Workpiece up to 2000 kg.
The program control in ZNC die-sinking EDMs is only on the Z axis. The positioning on the “X” and “Y” axes is carried out by means of entirely manual drives, which are not connected to the CNC of the machine.
The drives for the X and Y axes are equipped with comfortable handles and verniers, and for the convenience of the operator, the numerical values of the coordinates along these axes are shown on the machine display.
Historical note:
One of the first known applications of the EDM, which was created by the Lazarenko spouses, was the burning out of broken taps from the bodies of Katyusha missiles in the early 1940s.
I heard this from Lazarenko’s students.
However, in modern productions such tasks are quite common.

Technologies
Superior Spark Discharge Functions
EXCETEK EDM is built with MOSFET sparking circuits that provides less electrode wear and fast spark-erosion machining speed as well as achieving smooth surface roughness with finishing conditions.
Stable Generator Performance
Simple Maintenance
EXCETEK generator uses front and back assembly module design where the function of circuit indicates clear at each circuit which have fuse protection. This helps more easier for maintenance to check and (if necessity comes) exchange a PCB. This facilitates the maintenance and provides user friendly service for the customers and service maintenance personnel.
EXCETEK and EXCETEK distributors provide after sales and service maintenance which include Operation, Training, Maintenance and Application. According to vanguard’s professional management technology, we provide service quality and customer satisfaction for after sales service support.
