Exactly What Wire EDM Machines Can Perform To Your Company's Requirements?

By Aurelio Mellard


Wire EDM Machines can play an important role for your manufacturing and metalworking needs. If you need tools to operate on metal pieces, skip the conventional methods. For your drilling, milling, or grinding needs, electrical discharge machines may be everything that you need.

Wire EDM machines are a form of this type of cutting instrument that had its beginning in the 1960s, first patented in 1969 by an American mechanical engineer named David Dulebohn working for Andrews Engineering Company in Hopkins, Minnesota. Dulebohn and his engineering team would later advance the work of the wire EDM machine through the addition of a computer panel in 1974, thus creating the computer numerical controlled or CNC EDM machine that began widespread use in 1976.

Choosing the suitable wire EDM machine for your business begins with the appreciation of what these machines do. This awareness will allow you to determine which type of wire EDM machine would be feasible to meet your business needs.

What EDM Machines Do

Did you know electricity can be used to produce an erosive effect on metal? In the 1770, an English physicist named Joseph Priestly discovered this. And based on his discovery, electrical discharge machines, which include wire EDM machines, came into being.

Two centuries later, a Russian couple learned about Priestly's work and created the die sink electrical discharge machine. This device was more accurate and precise than the usual tools used for grinding, milling, or drilling. In fact, its precision even surpassed the accuracy of Dulebohn's wire EDM machine.

How EDM Machines Work

EDM machines focus electricity on the metal surface to cut it according to its predetermined pattern. To the operator's convenience, the machine can be programmed to trace the pattern with minimal human intervention, producing the desired output with utmost precision and efficiency.

Metalworking with Wire EDM Machines

Using the two common types of wire EDM machines, the traditional wire cut EDM machines and CNC EDM machines, you can easily perform metal cutting actions to meet your production and other manufacturing requirements. What separates both machines is its accuracy, precision, and automation features.

For more on matters relating to the scale and precision of wire EDM machines, it is best to consult a reputable manufacturer or dealer.

The different types of wire EDM machines available include those with a table base design or traveling column. Based on the type of work you need performed you should ask which type is best for the type of work you need performed.

For instance, a fixed-based traveling column type would best fit the machining needs of medical or aerospace industries. A closer look at the specifications of the different types of wire EDM machines can help you make a well-informed decision.
