ABOUT PECM
Pulsed electrochemical machining (PECM) is a non-contact, unconventional machining process based on the principles of electrolysis. The machining operation involves a tool (the cathode) in the inverse shape of the desired workpiece (the anode).
As the tool moves towards the workpiece surface, it machines the workpiece into the complementary shape of the tool. This occurs as a pulsed DC current is applied, allowing for high precision and superior surface quality. At the same time, an electrolyte is pumped between the cathode and anode at high speed, removing dissolved metal and heat.
The result is an operation capable of producing a burr-free 3D shape with no tool wear in alloys that are difficult or impossible to machine through traditional methods.

UNPARALLELED ACCURACY
Creating precision parts from advanced metal alloys is a growing challenge facing our customers.
Next generation PECM permits novel designs, produces higher quality parts, and can machine hard or temperature resistant alloys at higher speeds than competing technologies.
PECM is capable of machining any conductive metal or alloy and is particularly well suited for those materials that are difficult to machine through conventional methods. Commonly machined materials include nickel, iron, and titanium-based alloys in a variety of formats such as cast (including single crystal), forged, additively manufactured, and powdered metallurgy.
PECM is best suited for high-value metal components in highly stressed environments such as orthopedic implants, surgical tools, turbine engines, turbochargers, rocket motors, heat exchangers, sensors, and energy applications.
