| Space Station uses silicon carbide ceramic bearing Insaco, working with a major pump manufacturer, helped design a specialized pump to process wastewater into usable water on the International Space Station. To overcome both the requirement for reliability during manned space flights and the poor lubricity of water, Insaco recommended and machined a special grade of silicon carbide for their ceramic bearing with dimensional tolerances of +/-.0002". The pump has run in space successfully since 2016. For your unique machining requirements using sapphire, ceramic, quartz, and glass, trust the experts at Insaco.

| Direct-drive linear motors reduce operating costs and increase productivity Kollmorgen's new ICH family of Direct Drive Linear (DDL) servo motors improves overall equipment effectiveness by increasing productivity, reducing operating costs, and lowering maintenance costs through the reduction of mechanical components inherent in a direct-drive solution. When compared to conventional rotary systems, ICH linear servomotors increase throughput by up to 40% and enable the design of smaller, lighter machines with increased energy efficiency. The unique anti-cogging coil design provides smooth and quiet travel and delivers continuous forces ranging from 175N to 5341N and peak forces from 405N to 12,726N with voltage ratings up to 480 VAC.

| Cool Tools: New Bosch thermal camera for industry The Bosch GTC400C 12V Max Connected Thermal Camera is easy to use, determining temperatures in seconds and documenting the results with convenience. Featuring a large, illuminated color display, it delivers a 160 x 120 thermal graphic image accurate to +/- 3 C. It features simple operation: Just squeeze the trigger to shoot an image, and use the click wheel for the functions. The thermal graphic image features more than 19,000 measurement points for precision to show hot and cold spots, with the temperature at the center and an adjustable temp scale. The integrated visual camera records actual images, so the user can document the work area visually as well as thermally. This allows side-by-side comparison, picture-in-picture, and overlay of picture and thermal graphic. Nice long battery life.

Installing heat-set inserts into FDM parts Ricky Shannon, an application engineer on TriMech's 3D-printing team, has created an informative blog post on what to do if you need threads within your plastic 3D-printed part. Will the printed threads hold? They might, but Shannon says a more secured option could be to use heat-set threaded inserts in a secondary process. Learn all the ins and outs of the procedure. Tri-Mech is known for producing excellent tips videos and blogs -- from beginner to advanced. Check out more of their offerings under their Resources tab.
