Advantages Of Electrical Discharge Machine
 
01/

Electric Discharge Machining

Electrical discharge machines utilize electrical discharge machining, removing material through discharges between the electrode and workpiece. This non-contact machining method is suitable for conductive materials.

02/

High Precision

Electrical discharge machines can achieve very high levels of precision, making them ideal for workpieces with strict tolerances and surface quality requirements.

03/

Complex Shape Machining

Due to the lack of tool shape restrictions, electrical discharge machines can produce complex internal and external shapes such as holes, slots, and contours.

04/

Wide Applicability

Electrical discharge machines can process nearly all conductive materials, including hard alloys, steel, aluminum, etc., making them widely used in mold manufacturing, aerospace, automotive manufacturing, and other fields.

05/

High Surface Quality

Workpieces machined by electrical discharge machines typically have very good surface quality, often achieving very smooth finishes, reducing the need for additional surface treatments.

06/

Automation Features

Electrical discharge machines often come with automation features such as automatic electrode changing, automatic measurement, and automatic adjustment of discharge parameters, improving production efficiency and consistency.

07/

Low Heat Impact

Electrical discharge machine processes generate minimal heat because the discharge time is very short, helping to prevent thermal deformation and stress in the workpiece.

08/

High Machining Efficiency

Despite being a highly precise machining method, electrical discharge machines can achieve rapid material removal, particularly suitable for processing hard and difficult-to-machine materials.

09/

Multi-function Operations

Electrical discharge machines can perform various operations such as fine hole machining, internal and external cavity machining, threading, etc., suitable for different types of workpiece machining needs.

10/

Environmental Friendliness

Due to the minimal need for cutting fluids and reduced production of chips, electrical discharge machine is considered a relatively environmentally friendly machining method.

 

The Basic Principle Of Electrical Discharge Machine

 

The use of electrical discharge machine to remove material from the workpiece is achieved by a series of repeated rapid current discharges between the electrodes. These electrodes are separated using dielectric fluid. The voltage is sent through the dielectric fluid.


One of these electrodes is used to change the shape to suit the exact purpose. The electrode is a workpiece electrode or “anode”. The most commonly used electrode materials are copper, tungsten alloy, cast iron, steel, silver tungsten alloy, and graphite. The other electrode is the tool electrode or “cathode”. The basic principle behind this electrical discharge machine is to corrode materials with controlled electric sparks. The two electrodes must not touch.


A potential difference is applied between the workpiece and the electrode in the form of pulses. As the electrodes approach the workpiece, the electric field existing in the small gap between them increases. This continues until it reaches the breakdown level.

 

Uses of Electric Discharge Machines
 

Use in the Aerospace Industry
In the aerospace industry, electric discharge machines test parts for many different planes and spaceships.


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.


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.


Use in Precious Metal Refining
It's an industrial device usually used in large-scale metal refining processes that produce gold bars and pure silver sheets.

 

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.

Die Sinker Machine

 

Die Sinking EDM Machine

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.

 

Use in the Military Industry
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.

 

Use as Part of the Automotive Production Process
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.

 

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.

FAQ

 

Q: What is electric discharge machine used for?

A: Electrical discharge machining is a machining method primarily used for hard metals or those that would be very difficult to machine with traditional techniques. Electric discharge machines typically works with materials that are electrically conductive, although methods have also been proposed for using edm to machine insulating ceramics.

Q: What is the principle of electric discharge machines?

A: In electric discharge machines, a thin wire acts as the electrode and is continuously fed through the workpiece. The wire is electrically charged and, as it traverses the workpiece, generates a series of spark discharges. This process excels in precision and is particularly suited for creating intricate shapes and small parts.

Q: What is electric discharge machine?

A: Electric discharge machines is a non-traditional machining process based on removing material from a part by means of a series of repeated electrical discharges between tools, called electrodes, and the part being machined in the presence of a dielectric fluid.
