Isoparaffin for EDM Fluid

To meet industrial needs, novel materials with special mechanical properties such as high hardness, high brittleness and high toughness materials have been developed. Cutting these materials with existing traditional machine tools is no longer able to meet the current requirements for processed products. Therefore, the Electrical Discharge Machining (EDM) method with non-contact characteristics are more suitable for processing materials with high hardness, high brittleness and high toughness, especially for the nuclear energy industry or the aviation industry.

Isoparaffins are commonly employed as dielectric fluids in the electrical discharge machining (EDM) process. EDM fluids, also known as dielectric fluids, serve multiple purposes in the EDM process, including facilitating the electrical discharge, cooling the workpiece and electrode, and flushing away debris.

Here are some avantages of Isoparaffin used as EDM Fluid:

1. Electrical Insulation: Isoparaffin fluids have high electrical resistivity, meaning they act as good insulators. This property allows them to withstand the high voltage electrical discharges occurring during the EDM process without breaking down.

2. Thermal Stability: Isoparaffin have excellent thermal stability, which means they can withstand the high temperatures generated during the EDM process. They help dissipate the heat generated by the electrical discharges and prevent overheating of the workpiece and the electrode.

3. Low Viscosity: Isoparaffin fluids have low viscosity, which enables efficient flushing and removal of the eroded material and debris from the machining area. This helps maintain a clean and consistent machining environment, enhancing the accuracy and surface finish of the machined parts.

4. Compatibility: Isoparaffin are compatible with a wide range of materials commonly used in EDM, including metals such as steel, aluminum, and copper. They do not react with or corrode the workpiece or the electrode, ensuring a longer tool life and reducing the risk of workpiece contamination.

5. Environmental Friendliness: Isoparaffinic fluids are considered environmentally friendly compared to some other dielectric fluids used in EDM, such as chlorinated hydrocarbons. They have low toxicity, low volatility, and are non-flammable, making them safer to handle and dispose of.

Isoparaffin fluids offer excellent dielectric properties, thermal stability, and compatibility, making them suitable for EDM applications. They help improve machining efficiency, accuracy, and surface finish while ensuring a safe and environmentally friendly working environment.
