EP10 Chassis Features & Benefits

Free-standing unit with a small footprint
Allows clients to start small and economically

Heavy duty construction
From the EP10’s stainless steel uni-body construction, to its Teflon-coated cooling coil, all exposed materials used on the EP10 are built out of acid-resistant materials made to withstand the temperatures and the corrosive solutions used in electropolishing

Front access drain valve
Simplifies tank draining and maintenance

User-friendly touch-screen display
Can be customized to your specific application to simplify machine operation

Robust PLC machine control
Control and monitor all critical machine functions, including current, voltage and tank temperature, history/trending of process variables and allows you to save, modify, and select electropolishing “recipes” for different parts

Additional on-board I/O
Allows additional capabilities with no need to upgrade the PLC

Dedicated electropolishing power supply
Ensures consistent full power for the polishing process

Current and voltage regulation system with independent low-current alarm
Ensures each process is consistent and alerts users when a variance is detected

Operation indicator lights
Easily monitor multiple EP10 Chassis

Baffling controlled bath agitation system
Designed for precise tank flow control for specific applications

Electropolishing is an increasingly common method for polishing and deburring ferrous and nonferrous metals. Electropolishing systems work by smoothing, polishing, and deburring metal surfaces in an electrolytic bath. This process selectively removes high points on the metal surface while producing a uniform, high luster.

Electropolishing works by immersing a metal part in liquid media and subjecting it to direct current. The metal part becomes anodic (+) while another metal, usually lead, copper, or stainless steel, is used as a cathode (-). The direct current flows from the anode to the cathode, removing metal ions at a controlled rate. The amount of metal removed is dependent on the specific bath, temperature, speed, and alloy being electropolished.

Unlike conventional mechanical finishing systems, this process does not smear, bend, stress, or fracture the crystalline metal surface to achieve smoothness or luster. Instead, electropolishing removes metal from the surface while producing a unidirectional pattern that is stress- and occlusion-free, microscopically smooth, and often highly reflective. In addition, improved corrosion resistance and passivity are achieved on many ferrous and some nonferrous alloys. This same process is used for micro- and macro-deburring, as this reverse plating process selectively removes metal ions from high points on the surface without etching it.
