Bosch Rexroth modified its CKK and CKR Compact Modules for damp environment applications in the food and packaging industries. Key modifications for operating in damp environments include chrome plating of internal components. To reduce the likelihood of corrosion, all external hardware is stainless steel. In addition, holes can be drilled into the anodized aluminum housing to allow fluids to drain safely. The CKK uses a ball screw for system rigidity for heavy payloads or complex end-of-axis tooling. The belt-driven CKR uses a steel-reinforced polyurethane belt with aluminum pulleys. Both models have dual-ball rail system guides. With a load capacity up to 56,530N, the CKR operates at speeds up to 5 m/s. Full-contact seals retain the food-grade grease lubricant for both the ball rail and ball screw. Target applications include cartoners, laners, product sorting or diverting, filling and dispensing machines. For more information, go to http://rbi.ims.ca/4931-510.

Unlike his friends in engineering programs, blogger Jon Titus had little need for calculus except in a few of his college physical-chemistry labs and classes.
In the wake of the Chevy Volt fire investigations, sales are down, and General Motors' (GM) CEO Dan Akerson is blaming the downturn on a spate of bad publicity.
Thanks to embedded electronics, medical devices are getting smaller and smarter than ever. Pacemakers and implantable defibrillators are now able to call physicians. MRIs, CT scanners, and ultrasound machines are gaining mobility. And the venerable Band-Aid may soon be able to detect illnesses ranging from fevers to heart arrhythmias. On February 21, join Design News senior editor Charles Murray for a wide-ranging discussion, "Embedded Angles for Medical Products," which will explore the latest developments in medical electronics. The discussion will examine advances in medical device technology and offer an inside look at the embedded electronics behind it.
