Precision EDM Machining Service
Wire EDM Machining Service
Wire Electrical Discharge Machining (Wire EDM) is a precision machining process that uses electrical discharges (sparks) to cut and shape conductive materials. This process is highly valued in industries requiring high precision and intricate detailing, such as aerospace, automotive, medical devices, and tool and die manufacturing.
Advantages of EDM Service
There are several benefits plasma cutting as a method of metal fabrication has over others. These benefits include cost effectiveness, a wider range of metal cuts, high precision, and repeatability..
Precision
Capable of achieving tolerances within micrometers, making it ideal for intricate designs.
Complex Shapes
Can produce complex geometries that are difficult or impossible with conventional machining.
No Mechanical Stress
As a non-contact process, there is no physical force applied to the workpiece, minimizing the risk of distortion.
Hard Materials
Effective for machining hard materials such as tungsten carbide, titanium, and hardened steel.
Fine Surface Finish
Provides a smooth surface finish, often eliminating the need for further finishing processes.
Versatility
Versatility:
EDM can be used to machine a wide range of materials, including conductive metals, alloys, and even some non-conductive materials when coated with a conductive layer.
EDM Wire Process
EDM (Electrical Discharge Machining) is a specialized manufacturing process that uses electrical discharges to remove material from a workpiece, creating the desired shape or feature. The EDM process involves the following key steps:
Electrode Preparation
The cutting tool, known as the electrode, is fabricated to the desired shape and size, typically made of graphite or copper.
Workpiece Preparation
The workpiece, typically a conductive material, is secured in the EDM machine.
Immersion in Dielectric Fluid
The workpiece and the electrode are submerged in a dielectric fluid, such as deionized water or hydrocarbon oil.
Electrical Discharge
A controlled electrical discharge is generated between the electrode and the workpiece, creating a series of rapid and localized sparks.
Material Removal
The electrical discharges melt and vaporize small amounts of the workpiece material, creating the desired shape or feature.
Flushing and Filtration
The dielectric fluid flushes away the eroded particles, and a filtration system removes the debris from the fluid.
Automated Servo Control
The EDM machine’s servo system automatically maintains a precise gap between the electrode and the workpiece, ensuring a consistent and controlled material removal process.
How Wire EDM Works
The type of gas used during the process depends on the cutting method, cutting material, and thickness. Asides from ensuring the formation of a plasma jet, the gas used should also help expel molten material and oxide from the cut. The most common gases used for plasma cutting include;
Setup:
- A thin, electrically conductive wire (usually brass or molybdenum) is fed through the workpiece.
- The wire and the workpiece are submerged in a dielectric fluid (commonly deionized water), which cools and removes debris.
Cutting Process:
- High-frequency electrical pulses are discharged between the wire and the workpiece.
- These discharges create sparks that erode the material along the desired cutting path.
- The wire is moved along the programmed path, allowing for precise cuts.
Dielectric Fluid:
- The dielectric fluid helps to cool the wire and the workpiece.
- It also flushes away the eroded particles from the cutting area.
