External linear actuator is a rotating leadscrew design that incorporates ball bearings and a stainless-steel leadscrew in the motor's rotor. Shaft-to-leadscrew couplers are not needed for the actuator, making it targeted for use in limited-space applications. Available frame sizes include 20-, 26-, 36-, and 46-mm diameters. Step increments include 0.001, 0.002, 0.004, and 0.008 inch per step. The actuator is for medical devices, instrumentation, small machinery, office equipment, and any applications where precise, controllable linear motion is required.
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.
