At the NPE 2009 show in Chicago, half a dozen exhibitors showed new cooling equipment that emphasized improved performance at about the same or lower cost. Major themes at the show were new equipment to meet EPA restrictions on R22 refrigerant next year, adiabatic fluid coolers to provide ambient-air cooling, refinements in low-energy frictionless chillers, and several new or improved liquid tempe……

With NPE only recently ended, you might not expect much new equipment or processing technology to be revealed at Fakuma, the big injection molding show in Germany’s small town of Friedrichshafen. You’d err. Maybe the manufacturers needed those few post-NPE months to get these processing cells tuned, or maybe it’s simply a cost-saving move: Many of the leading machine OEMs are wit……

Reducing costs and achieving greater productivity within an existing mold manufacturing facility, while improving customer service, are all essential to softening the impact of these uncertain economic times. It’s a difficult challenge, but one that can be successfully met by initiating simple automation. Simple automation is the installation and integration of automated storage and retrieva……

An energy-efficient hydraulic fluid has been developed for use with CNC machines that features low-deposit forming tendencies, provides equipment protection and can extend oil maintenance intervals. Shell Tellus EE, developed by Shell Lubricants (Houston, TX)—a provider of lubricants technology solutions—can help companies save an average of 8 percent on energy consumption. Purchasing ……

Trochoidal toolpaths are available on most CAD/CAM systems, yet are rarely used or even known. By using trochoidal toolpaths and hybrid trochoidal toolpaths you can successfully machine exotic materials.The Common Ground Between Moldmaking and Aerospace article in the March 2009 issue (page 31) discussed some advanced programming techniques, such as trochoidal toolpaths. This article will cover th……

After presenting the first prototype of a new wire-cut EDM machine at Tokyo’s JIMTOF fair last year, Mitsubishi Electric plans to introduce its high-precision NA Essence wire EDM series to the European public at EMO Milano in October. The new high-end machine series combines revolutionary with evolutionary advances: it was redesigned from scratch, but takes advantage of the further developme……

The production of electrodes for die-sinking EDM represents one of the most difficult CNC programming challenges. The electrodes have complex geometries and must be machined with high precision. Also, they are produced in small lots, even one-offs, so programming time has to be as short as possible. The EDM Department, an American firm that provides EDM tooling and contract manufacturing, has been……
