Watch High-Speed Ultrasonic XY Motor [i]Align[/i]! This mini XY linear stage with piezo-ceramic motors combines sub-micron precision with excellent dynamics -- ideal for optics, medical design and photonics applications. In addition to the high speed up to 200 mm/sec, the low inertia (direct drive, no rotating parts) allows for a rapid start-stop behavior with settling times in the milliseconds. How can you use this XY stage?

High-tech Refractory Metal Fasteners for Extreme Conditions Refractory metal fasteners (nuts, bolts and washers) are ideal for situations that involve high temperature, high voltage, magnetism, and harsh corrosive environments. All four metals offered -- tungsten, tantalum, niobium and molybdenum -- are chemically inert, have a melting point above 2400° C, high hardness at room temperature, relatively high density, and stability against creep deformation at very high temperatures. Sizes range from M3 to M6. Have other questions? Email info@goodfellowusa.com.

| New joining gun system bonds metal and plastic in seconds | |
Scientists at the Fraunhofer Institute in Germany have developed a joining system that bonds metal and thermoplastic materials quickly. What's even better is that the modular gun can be integrated easily into the production process, for example by mounting on a robot arm in place of a spot-welding gun.

Robotics inspired by nature Since walking is a natural process, it's obvious that the designs and control systems of many walking machines are based on natural examples. In the case of LAURON (Legged AUtonomous RObot Neural-controlled), inspiration came from the Indian stick insect. The robot was designed for use in settings that are too hazardous for people, or are difficult to access with wheeled or chain-powered systems.

New ultra-lightweight ceramic aerogel handles extremes A UCLA-led research team has created a new type of aerogel that can better endure extremely hot conditions and big swings in temperature. The new material, based on dynamic nanoscale technology, contracts when compressed or heated, which is the opposite of most materials.

Army upgrading Black Hawk, Apache helicopters with next-generation GE engines Two U.S. Army workhorse helicopters, the Black Hawk and the Apache, are getting futuristic new engines that promise to keep the legendary choppers in service for decades to come. On Feb. 1, the Department of Defense awarded GE a $517-million contract to develop new engines for thousands of the airships in service over the next six years. By Brendan Coffey, GE Reports

Appearance models impress clients, designers alike Appearance models, the realistic prototypes produced with a combination of 3D printing, traditional manufacturing processes, and expert hand finishing, have a unique ability to dazzle. "Clients are amazed by the quality of the model, because they don't understand how it was made so quickly and realistically," says designer Robert Bronwasser. "It's some kind of magic for them." The "magic" of the model making comes from 3D Systems On Demand.

How a camera auto-focus lens uses a special spring Ultrasonic motors are small motors, some measured in millimeters, that are being used in a variety of applications including the auto-focus feature on a camera lens, side mirrors, surgical equipment, and robots. Learn how a single-turn closed wave spring is used to maintain the necessary pressure against the motor stator in a camera, and why it is a better choice in this application over coil or washer-type springs. Read the Rotor Clip application note.

Benefits of using military-grade adhesives in your applications Some epoxy compounds successfully meet thermal stability testing standard ASTM D3850-12 per MIL-STD-883J Section 3.5.2 and 3.8.5 for military applications, however these systems can also be used across many other industries where thermal stability is an important requirement. Some common non-military applications that benefit from compounds that pass MIL-STD-883J include downhole oil equipment, lasers, satellite systems, electronics, power tools, and various automotive applications.

Desktop Metal launches 316L stainless steel for 3D printing Desktop Metal, a 3D-printer maker, has just announced the launch of 316L stainless steel for the company's Studio System, the world's first and only office-friendly metal 3D-printing system. This machine is great for prototyping and low-volume production. A fully austenitic steel known for its corrosion resistance and excellent mechanical properties at extreme temperatures, 316L is well suited for applications in the most demanding industrial environments, including salt water in marine applications, caustic cleaners found in food processing environments, and chemicals in pharmaceutical manufacturing.

Top Tech Tip: Choosing between brush and brushless DC motors -- What are the tradeoffs? Designing a system that involves motion and performs as intended requires choosing the right motor. The most fundamental decision involves commutation type. In some cases, mechanically commutated brush motors provide the best solution for the budget. In other cases, only brushless DC (BLDC) motors will do. Allied Motion provides a comprehensive review of the technology, along with tips and tricks for choosing the right solution for a given application. Learn how to make the best motor choice (no registration required).

Un-weldable aluminum alloy now weldable thanks to nanotech AA 7075, an aluminum alloy developed in the 1940s, has long held promise for use in automobile manufacturing, except for one key obstacle. Although it's nearly as strong as steel and just one-third the weight, it is almost impossible to weld together using common techniques. But that's all changed.

| Nested Wave Springs from Smalley replace Belleville springs | |
| The need to stack individual springs for higher loads is no longer necessary. Nested springs result in a spring rate that increases proportionately to the number of turns. They can exert tremendous forces, yet maintain the precision of a circular-grain wave spring. In many applications, Nested Wave Springs replace Belleville Springs, particularly in cases where a high but accurate force is needed. Watch the Smalley video for more information.
