These guide systems are made for high speed and low cost. The Speed Demon OSG type and Speed Demon SG type systems run up to 10m per second (32.8 ft/sec), accelerate at up to 50 m/sec squared, and take loads up to 5,600N, or 1,259 lb. The OSG systems have five rail and block sizes, while the SG systems have seven rail sizes and 19 block designs. The rails in both systems have pre-drilled mounting holes, dual RC60 steel shafting and come in lengths up to 4m (13 ft), but can be ordered cut to size. The OSG blocks have four dual-contact roller bearings with two bearing on eccentric mounts, while the SG blocks have one, two or three bearings. OSG running straightness is +/- 0.02 mm (+/- .0008 inches), and the SG's is +/-0.015 mm (+/-.0006 inches). Both systems use felt wipers, high-angular dual-contact bearings, and corrosion-resistant materials. LM76http://rbi.ims.ca/4928-627
Parallax Inc. is known for developing the Basic Stamp microcontroller development board and educational accessory kits. In addition to developing a user-friendly educational platform to learn about 8-bit microcontrollers and software programming, it created a multicore 32-bit chip called the Propeller.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
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.
