Do you know the advantages of a mirror spark machine?

Mirror spark machining is mainly applied to the processing of complex mold cavities, especially for complex curved surfaces that are difficult to polish. It can eliminate manual polishing processes, improve the performance of parts, and is of great practical significance in shortening the mold manufacturing cycle. Therefore, it plays a very important role in the mold manufacturing industry. Let's take a look at the advantages of the mirror spark machine.

The CNC electric spark machine has designed two side repair programs: a flat-bottom square side repair scheme for sharp-edged rectangles, and a flat-bottom round side repair scheme for circular or multi-curved elliptical shapes. During the side repair process, the electrode moves towards the workpiece at an angle, while the tool electrode simultaneously moves from the center outward and from top to bottom, controlled automatically by CNC, achieving three-axis linkage. This motion method is not prone to carbon accumulation, facilitates chip removal and exhaust, and does not cause arc pulling, resulting in high production efficiency.

The CNC electric spark machine adopts a method of high-pressure breakdown followed by a complete low-pressure pulse, with equal pulse widths. Practice has proven that this pulse method further reduces the wear of the tool electrode, ensures a uniform roughness of the processed surface, and results in minimal wear on the tool electrode end face.

Outstanding discharge machining control system: standard configuration of 3-axis 3-linkage (optional 4-axis 4-linkage or 5-axis 5-linkage can also be achieved).

Automatic processing function (AUTO function), automatic positioning function, automatic arc clearing circuit, liquid temperature and level control, automatic fire extinguishing device, power failure recovery function, etc.

High precision, achieving high precision in machine tool processing (repeat positioning accuracy ≤2μm), high efficiency (≥500mm/min), surface finish (Ra ≤0.1μm), low electrode wear rate (≤0.1%), arbitrary axial lifting and servo discharge processing, complex four-axis four-linkage processing, suitable for various materials in the expert process database, etc., making it a high-performance cost-effective product.

The CNC electric spark machine has added special control in the control circuit. When an arc pull or false short circuit occurs, it immediately cuts off the pulse power supply, stopping the energy supply to the cavity, preventing the electrode temperature from rising further, thus reducing the possibility of fire.

Having introduced these advantages, I wonder if everyone has gained a deeper understanding of the mirror spark machine.
