Electropolishers: Parts Polishing

ESMA’s E399 model is the perfect piece of electropolishing equipment for high quality polishing of parts. Treatment of a part in the E399 will improve the part’s quality while helping to increase your facility’s production output by doing so quickly. When compared to mechanical polishing methods, an electropolisher is can be more efficient and practical and provide superior results.

The E399 comes complete with a digital timing and temperature to allow for the highest possible degree of reliability when polishing various parts. The maximum polishing output of the unit is 24 volts DC at 50 amps.

Electropolishing is a relatively basic process that employs electrical currents and some chemical reactions to thoroughly polish objects. Typically, the workpiece is immersed in a temperature-controlled bath of electrolyte and serves as the anode; it is connected to the positive terminal of a DC power supply, the negative terminal being attached to the in-tank cathode. A current passes from the anode, where metal on the surface is oxidized and dissolved in the electrolyte, to the cathode. At the cathode, a reduction reaction occurs, which normally produces hydrogen and oxygen. Scratches on the surface of the workpiece have peaks and valleys. The polishing or metal removal of the peak occurs more rapidly that in the valley and thereby smoothens the surface of the part.

Our E399 model comes loaded with lots of standard features that make electropolishing easier and more precise than ever before. These features include:

• A stainless steel cabinet
• Digital timer with push button start
• A voltage regulator with a digital DC meter
• Temperature controls and a cooling fan that can be turned off when not needed
• Inert cathodes
• A complete one year warranty on parts and labor
