About the Burlytic® Process



Electrochemical methods for removing burrs and polishing surfaces of metal components are in widespread use today. The most popular of the methods are electrochemical deburring (ECD, a.k.a. electrolytic deburring) and electro-polishing.


The Burlytic® Process is an advanced method of electrolytic deburring and polishing which is particularly suitable for high-quality components. Its major attribute is that it requires simple or no tooling to treat most machined parts.


The fundamental principle underlying the Burlytic® Process is not new. Also known as “reverse electroplating” this process has been used for a long time. Deburring and polishing occur when the workpiece is submerged in a conductive bath of Burlyte® Electrolyte and DC electric current is passed between the workpiece and a set of in-tank cathode screens. A cathode is simply a metal electrode of opposite polarity to the part. The part is always positive (+) and cathodes are always negative (-).


As electrical current passes through the part and electrolyte, and electro-chemical process takes place at the part surface. The electrical current concentrates at points (the burrs) and along the part edges (ref. Figure A). This effect causes metal to be selectively dissolved at the burred edges thus effectively removing the burrs and leaving the surfaces of the part mostly unaffected. The edges become slightly radiused.


While the amount of material removed from the workpiece is primarily a function of current and time, more deburring action occurs if the cathodes are placed closer to the edges but one of the many advantages of the Burlytic® system is that the cathodes can be placed at a distance. In many instances, the process deburrs without any locally placed cathodes; just submerge the part and run it. The process becomes essentially “self-tooling”.


The Burlytic® process is applicable to most metals, including steel, cast irons, stainless steels, aluminum alloys, copper alloys, magnesium alloys and refractory metals. It is highly discriminatory in that burrs are removed and sharp edges radiused while surfaces remain essentially unaffected. Many metals, particularly stainless steel, will automatically take on a high polish.


Most deburring applications are accomplished in 30 to 90 seconds. There are parts which may require several minutes and others that require only a few seconds. Since many parts can be fixtured together and processed at the same time, the per-piece cycle time is greatly reduced.


In our unique process there are some all-important differences that separate us from other electrolytic deburring equipment manufacturers. First, the voltage we utilize is not applied continuously, but rather in carefully timed pulses. Second, our electrolyte has a higher electrical resistance than electrolytes used in other commercial processes. In combination, these features produce a “peak effect” which causes selective dissolution of burrs and sharp edges. The degree of edge rounding and surface roughness reduction can be controlled by varying the process parameters. The deburring process is regulated enough that control can be fine tuned to a particular processing requirement.


Butlytic ECD Electrode
Burlytic® electrode must only be in the general area of the burr. The burr is dissolved from the tip of the burr to the root in a controlled manner. Deburring field is self-focusing.
