What is burr-free machining in fine hole discharge machining? Explanation of features and benefits!

Such hole drilling is impossible... If you think so, why not rely on a manufacturer specializing in fine hole discharge machining?

The Astec fine hole electrical discharge machining (EDM) machine is used in various industries with themes of "burr-free," "small diameter deep holes," "difficult-to-machine materials," and "automation." When you think about making a hole, you generally imagine drilling, right? The fine hole EDM machine can perform special machining and high-precision machining that is difficult with drills. What is burr-free machining? → By melting and evaporating metal using thermal energy, it enables machining that suppresses the occurrence of protrusions (burrs), which is a challenge in cutting processes, resulting in burr-free machining. Why can it handle difficult machining? → By utilizing the thermal energy of powerful electricity, it can machine materials that conduct electricity, including difficult-to-machine materials like hardened steel and carbide. What is the difference from drilling? → Since it is a non-contact process, it can smoothly machine curved surfaces and slopes without the worry of drill breakage, allowing for deep machining of materials up to about 1,500 mm thick. Is electrical discharge machining slow? → By spraying machining fluid from the inside of the pipe electrode, it achieves high-speed hole machining by efficiently discharging machining debris.
