Diamond-spark erosion grinding on metallic bond is a highly productive process used in working difficult materials. It is of considerable interest to investigate the efficiency of diamond wheels in the grinding of hard alloys while supplying impulse energy to the cutting zone. The efficiency of 150 x 10 x 3 ACK cup wheels made with ACB diamonds on MB1 bond as evaluated

The SETCO!" Spark Erosion Grinding (SEG) System is a portable electronic discharge machining system that precisely removes metal stock using AC current. The SEG process utilizes EDM technology to arc-grind a profile on metal parts. For over 20 years the SEG system has been used to machine honeycomb seals and rings for jet engines.

This is used as a process step before wire eroding, another type of spark erosion achieved through the use of an electric discharge machine. Wire eroding acts as a cutting process, during which a wire is fed through the workpiece and then, using an electrical current, the workpiece is brought to a melting point.

Horst Lach`s discovery of spark erosion for the economical processing of polycrystalline diamonds (PCD) in 1978 represents a milestone in the history of polycrystalline cutting tools. The electrical discharge grinding process provided for the first time the possibility of a quick, economical and high-quality grinding process of cutting edge

In spark erosion machining, a desired shape is obtained using electrical discharges, such as the case when cutting a honeycomb as part of the inside duct airflow system. The F-119 engine cooling duct is a honeycomb design that allows for only so much air to flow through the engine. Material is removed from the work piece by using rapid current

Sep 22,  · With spark erosion, EDM spark temperatures many times higher than copper’s melting point, certain applications using copper electrodes suffer from unacceptable electrode wear. With the advent of graphite as an electrode material, superior metal removal rates have been attained with far less electrode wear.

Spark Erosion Grinding (Honeycomb Grinding) Spark erosion grinding systems remove metal stock using AC current. The process relies on EDM technology, which allows manufacturers to arc-grind profiles onto metal parts. Aerospace and other professionals often opt to repair and reshape parts using spark erosion grinding rather than replacing expensive, specialized components.

Sep 15, · However, there are some PCD tools that require a ground surface finish, as there is a small degree of thermal damage using EDM. Even when running the EDM unit at a low speed—the faster the more thermal damage and the rougher the tool finish—with the right spark generator settings, surface finishes of ±1.5 microns, for instance, cannot be achieved.

Spark Erosion Explained. When dealing with difficult materials or complex shapes and sizes, spark erosion is one of the most successful forms of machining. There are no cutting forces so the integrity of the material is always maintained.
