Wire EDM vs. Gearradh léasair

In today’s advanced manufacturing landscape, two cutting-edge technologies have emerged as leaders in precision machining: Wire Electrical Discharge Machining (EDM sreang) and Laser Cutting.

Both processes offer unparalleled accuracy but operate on entirely different principles. Selecting the right method can significantly impact efficiency, costas, and the quality of the end product.

This article aims to provide an in-depth comparison of Wire EDM vs. Gearradh léasair, highlighting their strengths and helping you decide which technology best suits your needs.

1. What is Wire EDM Cutting?

Míniú

EDM sreang utilizes a thin wire—typically made of brass or copper—to cut through conductive materials by generating electrical discharges.

This non-contact cutting technique allows for the creation of complex shapes with tight tolerances without applying mechanical force.

Prionsabal oibre

Imagine a continuous spool of wire acting as the electrode. As it passes near the workpiece, controlled electrical pulses create sparks that erode the material.

The wire travels from a reel through the material and is collected on another spool. During this process, deionized water flushes away debris, ensuring a clean cut.

Materials Used
