Top 10 Uses of Electric Discharge Machines
Top 10 Uses of Electric Discharge Machines

If you are looking for a high-quality and comprehensive electric discharge machine manual, you've come to the right place! Electric spark machines are versatile tools, even though they're often overlooked. 
This is because they're not widely known and were replaced by more advanced tools that created electric charges more smoothly.
Electric discharge machines (aka plasma cutters) use high-speed electrodes to melt or cut through metal materials. A plasma cutter can burn through various metals with varying degrees of speed and thickness. 
Metal fabrication shops, machine shops and even homeowner workshops will find this is the tool for them. Here are the top 10 uses of EDM.

Top 10 Uses of Electric Discharge Machines

1.    Use in the Aerospace Industry

In the aerospace industry, electric discharge machines test parts for many different planes and spaceships. They're a great alternative to dropping real planes from high altitudes for testing purposes – which is far more dangerous! 
It's estimated that a plane must be dropped every time you want to test out one small piece of it. That would mean spending millions of dollars on drop tests when you could use an EDM instead. 
EDMs have also been used in several other industries – essentially any industry with some metal work or manufacturing process. That's just one way they're invaluable to companies around the world.

2.    Use in Power Tool Production

Electric discharge machining (EDM) is a process used to create parts from electrically conductive materials such as steel, copper, aluminium and titanium. It does this by removing material from the workpiece using an arc between a consumable electrode and an electrode on the machine tool. 
The shape of the resulting piece depends on the type of electrode being used, which can be flat-end, conical or ball-end.
EDM is commonly used to make precision components for power tools and other parts that require intricate shapes or tight tolerances, with applications including drill bits, scissors and valves. 
EDM also produces a finish that is hard to replicate with other manufacturing processes: Since the electrode leaves no particles behind, it has a smooth surface that resembles glass.

3.    Use in Jewelry Manufacturing

Electric discharge milling (EDM) machines help create jewellery parts because they can produce smooth surfaces free of burrs at exacting tolerances. They can mill shapes into gold or silver by removing tiny amounts of material at a time. 
This leaves the resulting component with a mirror-like finish and high material density, ideal for making rings or earrings with precious stones set into them.

4.    Use in Precious Metal Refining

Whether you're a jeweller, goldsmith, or just a hobbyist with a fascination for rocks or crystals, an electric discharge machine is a handy tool. 
It's an industrial device usually used in large-scale metal refining processes that produce gold bars and pure silver sheets. 
But it can also be used in small-scale ways by craftspeople who need to refine precious metals somehow.

5.    Use in Surface Tension Testing

An electric discharge machine helps bias surface tension measurements. It can be used to control the conditions of the surface the liquid is being tested on and the temperature and relative humidity of the air around it. 
Electric discharge machines are particularly effective when testing liquids that are either water-based or superheated above 100 degrees Celsius, which is why researchers and chemists commonly use them.

6.    Use in Pharmaceutical Manufacturing

An electric discharge machine is a device that uses high voltage to break down polymer molecules into more minor chemical compounds. In this process, polymers are heated and broken down into smaller molecules, and then the molecules are cooled and reformed into polymers. 
These chemical reactions occur at high speed and work to create polymers that can be used for anything from plastic bottles to prescription medication.

7.    Use in the Military Industry

Military technology is usually vastly different from civilian technology, and EDM technology is no exception. The US Army Corps of Engineers research division uses EDMs to etch circuit boards that go into military vehicles and weapons systems. 
This can be done at a much smaller scale than possible with any other method, which lends itself well to tight spaces and odd shapes common in military hardware design.

8.    Use as Part of the Automotive Production Process

EDMs have been used in automotive production since the late 1960s when General Motors introduced them as a replacement for electrochemical etching processes. 
Today, EDMs are used extensively in manufacturing automotive parts such as cylinder heads, intake manifolds and intake valves. 
The main advantage of EDM over other methods is that it can produce complex shapes with acceptable tolerances at high speeds and at low cost. 
This makes it particularly suitable for mass-production operations such as those in the auto industry where speed, accuracy and low cost are essential factors in determining success or failure in a competitive market.

9.    Use as a Tool for Cutting Metal

Electric discharge machines can cut through metal with ease and precision. These machines offer high speeds, which allows them to quickly cut through large amounts of material in just a few minutes. This makes them more efficient than other cutting tools like saws or drills.

10.    Use for Cutting and Welding Metals

Welders commonly use electric discharge machines to cut through metal materials. This can be done by using either an oxy-fuel torch or a plasma cutter to cut through different types of metals. 
These machines work by heating the metal and then applying pressure to the cut area. This causes the metal to become red hot and melt into two pieces.

Electric discharge machines are used in many applications, many of which focus on the manufacturing process. But these machines also have applications in research and even medicine. 
And while they are often made of expensive materials and created by a team of skilled engineers, the actual construction is not so complicated. 
These machines are typically creations that combine multiple concepts to create something new, with the individual components being primarily recycled from previous projects or tasks.

Our list hopefully provides insight into the various fields that use EDMs. We hope this list has been helpful, and we'd love to hear your thoughts on how EDMs can be applied to other areas in future blog posts.
