We have experience in developing many processes of precision electrochemical machining for many years.
Our highly qualified specialists can be proud of having practical experience in the use of PECM technology and our electrochemical machines SFE for manufacturing many complex precision products.
Improvement of our equipment, adaptation of PECM technology for manufacturing of many high-precision products are only some of our development goals in the very near future.
Precision Electro-Chemical Machining (PECM) of Metals is a modern high-tech high-precision method of machining conducting materials and alloys, which is based on fast dissolution of the processed detail material with simultaneous exposure to pulse current with electrolyte running through the interelectrode spacing between the processed detail material (anode) and the tool electrode (cathode).
During the process of precision electrochemical machining direct or reverse copying of the tool electrode shape and dimensions over the whole surface of the processed workpiece is performed.
By implementing only one electrochemical machining operation in the technical process of manufacturing articles it is possible to reduce the performance time of manufacturing a finished product by several times, eliminating a great number of mechanical and manual finishing operations, release workers and power intensive equipment.
Electrochemical machines SFE® are designed for precision electrochemical dimensional machining of conductive steel alloys and alloys with unusual properties.
Traditional methods of metal processing in our progressive time have already become outdated and do not give the desired quality and precision.
SFE machines solve these critical points, allow to manufacture products that are difficult to produce with the help of traditional technologies.
SFE provides a full control of all processes occurring during machining and creates an ideally accurate, mirror-processed product. Electrochemical precision machines SFE cover a wide range of processed materials: heat-resistant, high-speed, stainless, tool, alloy, structural, corrosion-resistant, high-carbon, chromium steels, as well as copper, bronze, brass, nickel, non-ferrous alloys, precious metals, magnets and magnetic alloys, stellite.
Precise Electrochemical machining (ECM, PECM) is based on the ability of a metal to dissolve as a result of oxidic reactions occurring in the medium of the electrically conducting solution (electrolyte) under electric current influence.
The dissolution process is called electrolysis.
Specific features of the electrolysis process are the spatial oxidation (dissolution) of the anode and the reduction (deposition) of the metal on the surface of the cathode. During the electrolysis, the anode and the cathode dissolve into an anion (negatively charged ions) and a cation (positively charged ions).
When these particles interact with the electrolyte, a forced reaction occurs under the electric field forces – to move accordingly to the cathode and the anode.
The resulting reaction of conversion into positive iron ions forms iron oxide hydrate which precipitates as an insoluble chemical compound. Thus, the electrochemical anodic dissolution of iron occurs.
ECM uses electrolytes in which cations do not precipitate during electrolysis on the surface of the cathode.
This method provides huge advantages of ECM: the invariance of the shape of the electrode tool.
