Where Can I Find EDM Machines?

By Trinidad Herke


EDM stands for electrical discharge machines. These devices are your best tools when you're working with hard metals in your fabrication and manufacturing business. Primarily designed for large-scale processing, EDM machines provide accuracy and overall production efficiency.

For smaller manufacturers of everyday items made of metal, such as small parts manufacturers or for some jewelry fabrication, there are other machines that may be more appropriate and less costly to perform the task.

Accordingly, it is important to know your needs first before getting EDM machines. In addition, understanding what these machines do and how they fit in the company's production goals is equally important. Before acquiring these gadgets, you should first learn to differentiate the many types of EDM machines and its functions. This should give you an insight of what type of EDM machine you should get.

What are EDM Machines

EDM machines go by different names or references. They have been called spark machines or eroding machines, which is a reference to the process that the machine uses to cut metal. They can also be referred to as burners, die sinkers and wire eroding machines. There are two basic types of EDM machines.

Created in the 1940s, die sink EDM are also known as R-C Type machine. R-C type pertains to the electrical circuit that charges the cutting electrodes on the EDM.

The second type is the wire cut EDM. This type of EDM appeared two decades after the first type appeared. These devices are usually found in large-scale manufacturing processes, operating on predetermined patterns or under a definite set of parameters.

The introduction of computers to machines created a computer numerical controlled or CNC EDM that came into use in the mid-1970s.

History of EDM Machines

Did you know the first generation of EDM machines first came out during the Second World War? The next generation came into being during the 1960s; they were invented by a mechanical engineer named David Dulebohn. After its US patent registration, by Andrews Engineering Company, was finalized, other EDM machines were produced by various manufacturers in the US and abroad.

Best Places to Find EDM Machines
