New Precision Electrolytic Machining System Introduced

PEM Technologies is set to unveil its new Precision Electrolytic Machining (PEM) machine in North America this September at the PEM Technology Process Development Center in Natrona Heights, PA.

The PEM1000 is intended to provide advanced process capabilities including wider ranges of pulse, oscillation and programmable sequences. PEM capabilities now include rotary machining, automated feed-thru and programmable X - Y positioning. In addition to the standard units, custom multi-axis units are available.

"With Electro-Chemical Machining (ECM), metal is machined through the use of electricity and chemistry to quickly and accurately remove metal and produce the desired end product," said a company spokesperson. "PEM technology has extended and improved the application possibilities associated with conventional ECM, allowing highly accurate full form features to be manufactured in most 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," said Don Risko, Vice President of PEM Technologies. "The specific advantages of PEM-machined workpieces include an extensive range of applications including medical, automotive, tool and die, diesel, fluid power and consumer products."

According to the company, the benefits of PEM technology include:

• The ability to machine metals to tolerances of ±.0002" (5 µm) 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
• High 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
• No mechanical contact, therefore no stress produced in workpieces
• 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 produce complex structures is possible.
