These joints are highly resistant to corrosion, with 316L stainless steel yokes. PTFE coating on the yokes' contact surfaces improve friction properties and prevent galling in the joints. Pins and blocks, also made out of 316L stainless steel, are protected with grease-packed boots. Standard single joints can be modified with 304, 316, 17-4, 15-5 or other steel grades. Sizes range from ½ -inch (13 mm) to 6-inch (153 mm) diameters with a standard operating angle of 35 degrees. Belden Inc.http://rbi.ims.ca/4928-608
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
