Introduction to SHF-25E EDM Filter

The SHF-25E  EDM filter adopts advanced filtering technology and materials, offering high filtration performance and reliable operational capabilities. It typically consists of filter cartridges, filter nozzles, seals, and housing. The filter cartridges effectively remove impurities, metal chips, and particles from the machining fluid, ensuring cleanliness and stability of the fluid. The filter nozzles are used to guide and distribute the flow of the machining fluid, ensuring uniform filtration results. It is also widely used in various wire cutting machines and machining scenarios.

Working principle of SHF-25E filter

Machining fluid enters the filter: The machining fluid enters the SHF-25E filter through pipelines from the circulation system of the wire cutting machine.

Centrifugal Separation: When the machining fluid enters the filter, it enters the centrifugal chamber. Inside the centrifugal chamber, the machining fluid generates centrifugal force through rotation.

Impurity Separation: Due to the action of centrifugal force, heavier impurities and solid particles are pushed towards the walls of the centrifugal chamber and deposited inside the filter.

Clean liquid collection: After centrifugal separation, the clean liquid fraction will form an empty vortex in the center of the centrifugal chamber and be collected at the center outlet of the filter.

Impurity Discharge: The impurities and solid particles deposited inside the filter are regularly discharged. This is usually done by opening the drain valve or by disassembling the filter.

Application of SHF-25E Filter in the Field of Wire Cutting

Metal Processing: The SHF-25E filter can be used in wire cutting processes for various metal materials, including steel, aluminum, copper, and more. It effectively filters out impurities and metal chips from the cutting fluid, maintaining its cleanliness and stability, thereby improving cutting precision and surface quality.

Mold Manufacturing: Precision and quality of the mold are crucial for the quality of the final product in the wire cutting process. The SHF-25E filter can be applied in wire cutting processes during mold manufacturing to ensure the cleanliness of the cutting fluid, preventing impurities from affecting the mold surface, and improving mold processing precision and lifespan.

Parts processing: The SHF-25E filter is suitable for parts processing in various industries, such as automotive, aerospace, electronics, etc. It can filter impurities and particles in the processing fluid, maintain the accuracy and clarity of the cutting line, and improve the processing accuracy and quality of parts.

Precision Machining: The SHF-25E filter plays a crucial role in processes that require high precision machining, such as micro-component machining and precision instrument manufacturing. It can filter out minute impurities in the cutting fluid, preventing any negative impact on the machining area, and ensuring precision and stability in the machining process.

Maintenance and Repair Tips for the SHF-25E Filter

Regularly cleaning the filter helps maintain its proper operation and filtering efficiency. Disassemble the filter and clean the filter element and filter nozzle using an appropriate cleaning agent or solvent. Ensure thorough rinsing of the filter and allow it to completely dry before reinstallation.

Filter element replacement: According to the usage and manufacturer’s recommendations, replace the filter element regularly. Choose the correct type of filter element compatible with the SHF-25E filter, and follow the steps in the instruction manual to replace it. Make sure to use the proper tools and proper installation methods.

Seal inspection and replacement: Regularly inspect the seals of the filter, such as O-rings or gaskets. If any signs of aging, damage, or looseness are detected, they should be promptly replaced. Choose the correct specification of seals that are compatible with the filter, and follow the proper installation method.

Inspect and clean pipes regularly: Make sure the pipes around the filter are clean and free from blockages. Regularly check that plumbing connections are tight and that there are no leaks. Removes impurities or particles that may clog or prevent the filter from functioning properly.

Troubleshooting and repairs: If you encounter any malfunctions or abnormal situations with the filter, first refer to the manufacturer’s provided maintenance manual or technical support documentation for troubleshooting guidance. Follow the instructions to troubleshoot the issue. If the problem cannot be resolved, it is recommended to contact the manufacturer’s technical support team or professional repair personnel for assistance.
