Advantages of the PECM process
No wear of the electrode tool.
There is no wear of the electrode tool during the precision electrochemical machining (PECM) on the SFE machine.
High processing efficiency.
The efficiency of the electrochemical dimensional forming is 1200 mm3/min and is characterized by the speed of the anodic dissolution of the metal, expressed in linear (mm/min) or in volumetric (mm3/min) units.
High roughness of processed surfaces.
With ECM, the quality of processed surfaces is determined by roughness and can reach 0.02 μm.
Machining accuracy, repeatability of dimensions depend on the quality of the electrode tool and processing modes.
Processing speed is 10 ... 100 times higher than that on electroerosive machines.
The average processing speed of the SFE machine for metal of any strength is 0.15 mm/min.
Control and improving the quality of parts.
Changing parameters of the processing capacity (adjustment of the process current) increases the quality of the part surface.
Ecologically clean PECM process with the use of a 12% aqueous solution of sodium nitrate (NaNO3)
Electrically safe process of machining at low voltages (4-12 Volts).
Processing metals of any hardness.
PECM technology allows processing the metal, hardened to any hardness.
Low-temperature processing modes.
PECM is conducted at low temperatures, without thermal stress and microcracks.
Absence of burrs and a defective layer after electrochemical machining.
Repeatability of dimensions and parameters in the batch when machining with one electrode tool.
