Electrical discharge machine filter Transor Filter Systems

Benefits

One of the most important aspects of EDM performance is flushing. Transor stresses the importance of providing dielectric filtered to a continuous and absolute one micron for flushing. Fewer and smaller particles result in a predictable environment where the following EDM benefits can be achieved

Reduced Machining Time=Faster Cuts

Without clean dielectric, microscopic particles present in the oil can interfere with effective machining of the workpiece. If present in sufficient quantities, the frequency of discharge will be reduced and the electrode will back away from the cut. Transor's one micron filtration helps to eliminate this contamination contributing to efficient performance at optimum machining speed.

Improved Accuracy

Geometric shapes may be deformed and tolerances not achieved when dielectric is contaminated by conductive particles. Again, Transor's one micron filtration capabilities minimize these particles which interfere with the controlled discharge machining of the sidewalls of the cavity. Clean dielectric is essential to achieve the repeatability and close tolerance requirements of production and multi-cavity mold applications.

Reduced Pitting=Reduced Polishing

Particles bridging the gap between the electrode and workpiece convert the AC current used in EDM to DC current. This causes a concentrated discharge, resulting in arcing and pitting that damages the electrode or the workpiece. With dielectric filtered to one micron, more consistent current allows finer surface finishes that reduce polishing time.

Cost Justification

Users of the Transor System point to two areas of savings.

First, Transor's automatic cleaning of the filter elements eliminates the cost and down-time of changing standard cartridges.

Second, and MOST IMPORTANT, machining with oil filtered to one micron produces significant benefits over standard five micron paper cartridges. Reduced machining time, improved accuracy, and superior surface finishes have produced documented increases in overall EDM efficiency of anywhere from 5% to 35%. Transor specializes in EDM filtration. From individual units to centralized systems for multiple EDM's, one micron filtration provides dramatic improvements in EDM efficiency.
