Sinker EDM

Sinker EDM, employs machined electrodes of varying shapes, sizes and materials to remove material from the workpiece. Electrodes are usually made from graphite, but copper, tungsten or brass as well as combinations of these materials are also used, and the geometric features of the electrode can be customized to reach the required specifications.

Die sinker EDM (also known as RAM EDM and plunge EDM) was independently invented and almost at the same time as someone else. In 1941, two inventors were place with an assignment to find some way to try to boost tungsten breaker points' lifespan; these inventors were Russian inventors known as Boris and Natalya Lazarenko.

EDM 101: Electrical Discharge Machining Basics

Sinker EDM sees a similar pattern, with most jobs using two electrodes: one for roughing and one for finishing. "With sinkers, there's a standing joke that you don't want to use a sinker EDM unless you absolutely have to: if there's no other way to get the shape you need into the part," said Langenhorst.

Casting Dies EDM Electrodes Manufacturer from

As Graphite does not melt so the electrode wear is very minimal unlike copper. Density of Graphite is 4 – 5 times lesser than copper, which saves money in weight as well results in lighter electrodes. But EDM electrodes choosing are very important whilst doing

Back to Basics (4/6): Sinker EDM Machine Basics

2020/4/6Sinker EDM machines can be equipped with automatic tool changers to enable long, unattended run times. Multiple electrodes then can be used for roughing and finishing operations. These machines also can be loaded and unloaded with fixtured workpieces in robotic cells to increase productivity by maximizing unattended operation.

General EDM Discussion Basics on sinker EDM

2014/6/27The basic idea is that you make something, usually in graphite, that closely resembles the cavity you're trying to produce, and then the sinker EDM burns it into a steel block in one go. This is a lot quicker than trying to carve a complex cavity repeatedly, and justifies the extra expense and difficulty involved in working with graphite and the EDM process.

Electric Discharge Machining, EDM, Spark Machining, Die

Electrodes for electrical-discharge machining (EDM) are made of graphite, brass, copper and copper-tungsten alloy. Electrode diameters down to 0.1mm are possible. Since tool wear is an undesired phenomenon adversely affecting dimensional accuracy in EDM,
