Wire erosion machines are advanced manufacturing technologies that offer significant advantages in the production of parts with high precision and complex geometries. Operating on the principle of electrical spark erosion, these machines enable the shaping of hard materials without chip removal. This allows for reliable and repeatable results, particularly in sectors such as mold making, medical, and aerospace, which require micron-level tolerances.
The absence of cutting force during wire erosion eliminates the risk of deformation in the part. Surface quality is achieved with high precision thanks to controlled spark energy and a clean dielectric environment. High accuracy can be achieved even with heat-sensitive materials. At the same time, the reduction in scrap rates and shorter workpiece changeover times during the production process contribute to overall production efficiency. With these features, wire erosion machines stand out as an indispensable technology for applications in modern industry where quality and precision are paramount.
During the wire erosion process, continuous electrical sparks occur between the wire electrode in the dielectric fluid and the workpiece. The micron-sized metal particles and process residues generated during this process negatively affect the cleanliness of the dielectric fluid. The filtration system maintains the stability and precision of the process by removing these particles from the environment.
The cleanliness of the dielectric fluid directly affects spark stability, cutting speed, and surface quality. Mikropor’s MEDMF – Wire Erosion (EDM) Machine Filters contribute to keeping the dielectric fluid continuously clean by providing high filtration efficiency relative to particle size.

The role of filters is not limited to keeping the fluid clean. Dirty or clogged filters hinder the circulation of the dielectric fluid. This can lead to a decrease in cutting speed, deterioration of surface quality, and reduced process stability. Furthermore, failure to regularly check the filtration system can lead to accelerated wear of the electrode wire and reduced processing accuracy. Therefore, the use of filters with appropriate capacity and quality is critical for machine performance and production continuity.
MEDMF filters allow more particles to be captured thanks to their pleated design, which increases surface area. However, over time, particles accumulating on the filter material can cause clogging and increased pressure drop. This can shorten the filter’s service life and lead to unplanned downtime.
Mikropor has developed filter materials that offer low pressure drop, reach saturation in an optimal time, and provide a long service life by analyzing the fiber structure used in filters in detail. SEM images of the material used in MEDMF filters reveal this structural optimization.

MEDMF filters can be safely used in wire erosion processes involving different materials such as copper, aluminum, manufacturing steel, and carbide. In addition to their long service life, the user-friendly handle design makes filter replacement quick and practical, facilitating the maintenance process and supporting production efficiency.
In light of this assessment, it is clear that wire erosion filters play a critical role in the production process, although they are often invisible. Regular maintenance and timely replacement of the filter directly affect the stable operation of the machine and the precision of the parts produced. A clean dielectric fluid enables more stable spark formation and higher surface quality, making the filtration system not just auxiliary equipment but one of the key determinants of production quality. Therefore, selecting the right filtration solution at is not merely a consumable choice but a strategic decision that directly impacts process quality.
