Developing Story: Kobe Steel admits falsifying product data, 500 companies affected
Japanese metals company Kobe Steel Ltd. has admitted to "improper conduct" where "data in inspection certificates had been improperly rewritten." Some materials the company produced over the past 10 years may not have been up to snuff in terms of strength and/or durability. Some inspection reports were falsified. The problem affects a ballooning number of international companies.

Ceramic pump moves 1,400-deg C molten metal!
A ceramic-based mechanical pump able to operate at record temperatures of more than 1,400-deg C (1,673 Kelvin) can transfer high-temperature liquids such as molten tin, enabling a new generation of energy conversion and storage systems. Use of ceramic components, normally considered too brittle for mechanical systems, was made possible by precision machining -- and seals made from another high-temperature material: graphite.

Motor Tech:
UAV camera stabilization with brushless motors

Today, recon is dominated by unmanned aerial vehicles (UAVs) and drones due largely to concerns for pilots’ safety and costs. However, photos and videos obtained from UAVs are only useful if they are crisp and clear, which requires both precise focusing and extreme stabilization of the camera system. Compact and powerful FAULHABER brushless DC motors from MICROMO were selected to get the job done.

Image - Alternative to traditional drive systems
Alternative to traditional drive systems
Nexen Group has introduced a stainless steel version of its patented precision roller pinion system (RPS). The Nexen RPS engages two teeth simultaneously to achieve superior accuracy with zero backlash at any length. The system is also extremely quiet and 99% efficient. Stainless steel makes the system corrosion resistant, with a long life of up to 36 million meters. Nexen’s RPS provides a low-maintenance, durable alternative to rack and pinion, ball screw, and belt drive technology. The RPS is used for a wide range of applications including laser cutting, plasma cutting, and gantry applications.

Great Resources: Urethane casting tips and tricks
Xometry's team of engineering experts has created a no-cost design guide to help you optimize your urethane casting designs. Urethane casting creates rigid or flexible end-use parts that are highly durable. This process is optimal for low- to mid-volume production runs, and little to no finishing is required because desired textures and finishes are applied to the master pattern. This design guide focuses on how to save time and money on your next casting project.

Astronauts prove humans are more fun to spin than fidget spinners in space
What's so fun about spinning a fidget spinner in space? Well, not much, as NASA astronaut Randy Bresnik proves in a new Youtube video shot on the ISS. "Allowing the fidget spinner to float reduces the bearing friction by permitting the rate of the central ring and outer spinner to equalize, and the whole thing spins as a unit," says Bresnik. But watching the crew spin is way more entertaining!
