PEM PROCESS TAKES ELECTRO-CHEMICAL MACHINING TECHNOLOGY TO NEW LEVELS

PEM Technologies‘ (Ridgefield, NJ) Precision Electrolytic Machining (PEM) Process takes Electro-Chemical Machining (ECM) technology to a new level of precision and accuracy. With ECM, metal is machined through the use of electricity and chemistry to quickly and accurately erode and produce the desired end product. PEM technology has significantly extended and improved the application possibilities associated with conventional ECM, allowing highly accurate full form features to be manufactured in almost any metallic material, particularly those that are difficult to machine by conventional methods.

“The PEM process gives us the ability to create highly complex geometrical shapes with extremely high tolerance,” says Don Risko, vice president of PEM Technologies. “The specific advantages of PEM-machined workpieces offer an extensive range of applications including medical, automotive, tool and die, diesel, fluid power and control.”

The benefits of PEM Technology include:
– The ability to process virtually all metals and alloys in large or small quantities
– Speed is not dependent on hardness or toughness of the material; exotic or hard alloys can be machined just as quickly as soft material
– Parts are machined burr free and finished in a single operation
– Fast machining rates with high production repeatability
– Electrode replication accuracy is increased by employing a very small working gap; thus significantly smaller structures and shapes such as prongs, holes, cavities and inscriptions are easily produced
– With no mechanical or thermal load on the tool, there is no mechanical wear, offering extremely long tool life
– Simultaneous production of many parts in parallel is possible
– Sequential rough machining then very fine machining to quickly produce highly-complex structures is possible.
