Business Description

Since the introduction of spark erosion technology, our commitment to advancing manufacturing processes has led to significant enhancements, especially in mold and tool making. Our innovative functional coatings for EDM wire have delivered impressive results, boosting material removal rates and achieving a remarkable 40% reduction in machine running times during daily operations. This efficiency gain translates directly into a substantial cut of up to 40% in production costs, making the adoption of coated wire in spark erosion a game-changer for cost-effective and streamlined manufacturing.

Electrical Discharge Machining (EDM) has a rich history that began with Joseph Priestly's observations in 1770, which sparked the exploration of electro-discharge erosion. In the 1940s, Soviet researchers, the Lazarenkos, made significant strides in the development of wire EDM and small-hole EDM. Today, EDM is recognized as a precise and efficient technique for removing material from conductive workpieces, commonly referred to as wire EDM, wire erosion, or electrical discharge machining.

The EDM process relies on controlled electrical discharges, or sparks, between two electrodes: the tool electrode and the workpiece electrode. These sparks occur millions of times per second, generating intense heat that melts or vaporizes the conductive material. By maintaining a consistent spark gap between the electrodes, EDM ensures stability and precision. Unlike traditional machining methods, EDM uses electrical discharges rather than mechanical force to erode the material's surface. Both the tool and workpiece are submerged in dielectric fluid, typically deionised water, which cools the process and removes eroded particles.

Wire EDM, also known as wire-cut EDM or wire erosion, employs a thin metallic wire to cut or shape conductive materials. The wire follows a precisely programmed path without making direct contact with the workpiece, which prevents distortion. Charged to a specific voltage and surrounded by deionised water, the wire generates sparks that erode the workpiece's surface. This method allows for the creation of intricate shapes with varying tapers and profiles, making it ideal for delicate or complex components.

Wire EDM machines operate with four independent axes, enabling the production of intricate shapes, tapered cuts, and precise molds. This technology is invaluable for machining thick parts that require high accuracy and excellent finishes, as well as for creating complex shapes, narrow slots, and detailed designs. It is also highly effective for large components that demand tight tolerances and for processing delicate, hard, exotic, or fragile materials.

Small-hole EDM utilizes hollow electrodes that spin like a drill bit to create tiny holes in workpieces. These holes are produced through controlled electrical sparks that erode the material's surface, guided by CNC codes. The addition of automatic electrode changers enhances efficiency, making the process both reliable and precise.

In conclusion, EDM and its variants, particularly Wire EDM and Small Hole EDM, are transforming precision machining.
