OUR TECHNOLOGY

Voxel has developed a Pulsed Electrochemical Machining (PECM) process that enables unique geometries, faster machining times, and better tolerances than competing manufacturing technologies.

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.

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 is moved towards the workpiece surface, a pulsed DC current is applied and an electrolyte is pumped between the cathode and anode at high speed. The pulsating DC power supply allows for high precision and superior surface quality while the electrolyte removes dissolved metal and heat. As the tool moves towards the workpiece, the workpiece is machined into the complementary shape of the tool. 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.

Cathode and anode are set-up and electrolyte is pumped between the two parts.

Step 1

As the two pieces move together a pulsed DC current is applied to the anode and cathode.

Step 2

The flowing electrolyte removes heat and waste products from the gap.

Step 3

The workpiece is machined into the complimentary shape of the cathode tool.

Step 4

Part is complete with no need for any secondary processing, burr removal, or polishing.

Step 5
