What do you know about the advantages of mirror sparking machines?

Mirror spark machine processing is mainly used in complex mould cavities, especially the complex surface of the polishing operation is not convenient for processing, can eliminate the manual polishing process, improve the performance of the parts, to shorten the mould manufacturing cycle, has a very important practical significance. Therefore it has a ten important role in the mould manufacturing industry. Let's learn more about the advantages of the mirror spark machine.

The CNC EDM machine is designed with two side trimming programs, a flat bottomed square side trimming program for angular rectangles and a flat bottomed round side trimming program for round or polycurved ovals. During the side trimming process, the electrode is fed into the workpiece at an angle, while the tool electrode moves from the centre to the outside, from top to bottom, with automatic CNC control, i.e. a three-axis linkage. This type of movement is less prone to carbon build-up, easy chip exhaust, no arc pulling and high production efficiency.

The EDM uses a high voltage penetration followed by a complete low voltage pulse with equal pulse width, which has proven to further reduce the loss of the tool electrode, the surface roughness is uniform and the loss of the tool electrode end face is minimal.

Outstanding EDM control system: 3 axes and 3 linkages as standard (4 axes and 4 linkages or 5 axes and 5 linkages are available as options)

Automatic machining function (AUTO function), automatic positioning function, automatic arc cleaning circuit, liquid temperature and level control and automatic fire extinguishing device, power-off reset function, etc.

High precision to achieve high accuracy (repeat positioning accuracy ≤ 2μm), high efficiency (≥ 500mm/min), surface finish (Ra ≤ 0.1μm), low electrode loss rate (≤ 0.1%) of machine tool processing, any axial lifting and servo discharge processing, complex four-axis quadruplex processing, expert process database processing suitable for various materials, etc. It is a high performance-price ratio product.

The CNC EDM adds special controls to the control circuit to immediately cut off the pulse power supply and stop supplying energy to the shaped cavity when an arc pull or false short circuit is generated, and the electrode temperature does not continue to rise, reducing the possibility of fire.

After introducing these advantages, I wonder if you have a better understanding of the mirror sparking machine
