Most Common Risks and Hazards of Spark Erosion Machining

03 December 2021

Spark erosion is directed through metal disintegration machines (MDM). These machines use terminals to send low voltage/high flow electrical charges that dissolves the assigned piece of metal simultaneously cool water thermal stuns the liquid steel and beats it into miniature size pieces and flushes it away.

Since there is no immediate contact between the cathodes and the machine casting, spark erosion permits you to work with even the most intricate segments and frail materials without risking mutilation. It is precision that makes spark erosion the best method to reuse parts that would otherwise be considered unusable.

Advantages Of Using Spark Erosion Machines

There are a few advantages in spark erosion machines, some of which include: direct activity, unsurpassable cost, moderately lightweight and easy to manoeuvre, speedy arrangement and breakdown, effectively manageable for one individual, and practically zero maintenance; essentially keep it loaded up with new coolant.

Spark erosion is the quickest and most practical answer for recovering machinery from broken equipment. Consistently, specialists have been perfecting this process and supplying premium metal disintegrators at moderate costs globally.

Cutting Tool Limitations

Thin-edged saw blades and fine-grain grinding discs are regarded as fundamentally essential machine shop tools. However, they have limitations. A blade will always have trouble laying down a complex geometrical profile. And, should that geometry be required on a hardened metal workpiece, a whole new set of problems seem to appear to vex a project manager. Heat stress, as caused by the blade’s rubbing, alters the microcrystalline structure of the metal. The temperature rises so high, so rapidly, that it deforms the alloy. Again, while not impossible, it’s not easy to apply intricate shapes with conventional cutting tools. No worries, there’s a technology that doesn’t require any contact. Since they are used to create those intricate shapes, the aforementioned frictional hardships become a non-issue.

High-Energy Spark Erosion Technology

Upon discharging the energy, thousands of these eroded voids form highly focused incision marks. The non-contact electrical charge is highly controllable and capable of applying the finest cuts. They can then travel in any direction, as guided by a system of state-of-the-art motion controlling electronics. All the while, as the intricate shapes are applied, there’s no frictional heat generated, so there are no changes to the metal, no material deformations, and no poorly applied cuts to undermine the process.

Spark erosion work is used to manufacture high-tolerance aeronautics and marine components. Hardened tool metals or softer alloys, it’s all the same, the electrode charge erodes and vaporizes dense or soft metals with equal alacrity. In-process, the workpiece to receive a series of detailed dimensional shapes is sunken into a liquid dielectric, which acts as a circuit insulator and debris flusher. Not that there’s much debris, with the erosion electrode vaporizing 10,000 of those tiny subtractive craters per second. With oil and gas applications, the die-making sector and countless other high-tech applications specify high tolerance. They also focus on dimensionally accurate parts above all else. Spark erosion work has never been in more demand than it is right now.
