EDM Filters
SST proudly distributes the most popular filter brands in the industry with a selection that ranges from economy filters to high-end.
Selecting the best EDM (Electrical Discharge Machining) machine filters begins with understanding the specific filtration requirements of your application. Key factors include the micron rating and filtration efficiency, which determine the size of particles the filter can capture and how effectively it maintains fluid purity. For most wire EDM machines, filters rated at 1–5 microns are preferred for achieving high-quality surface finishes and dimensional accuracy, while sinker EDM machines may require filters in the 5–10 micron range. The type of material being machined also matters: softer metals and roughing operations may generate larger debris, requiring different filter ratings or pre-filters to optimize performance and filter lifespan.
Compatibility with your machine’s dielectric fluid and operational setup is essential. Not all filters are suitable for every type of dielectric fluid, so ensure the filter media is chemically compatible to prevent degradation and maintain effective filtration. Additionally, consider the filter’s flow rate and pressure drop characteristics—selecting a filter that matches your machine’s circulation system will help avoid reduced efficiency or clogging. Some advanced filter types, such as self-cleaning or magnetic filters, are designed for specific needs like continuous operation or removal of ferrous particles, and may be beneficial depending on your workload and maintenance preferences.
Finally, balance cost with long-term performance. While lower-cost filters may seem appealing, high-quality filters often provide better durability, longer service life, and improved machine protection, ultimately reducing downtime and maintenance expenses. Evaluate the filter’s construction quality, ease of replacement, and manufacturer support. Consulting manufacturer specifications and, if needed, seeking expert advice can help you select a filter that maximizes both productivity and machine longevity for your specific EDM operations
