 | Download Photo Etching Precision Parts Guide
This Tech-Etch guide describes how photo etching produces prototype quantities and large production runs of precision parts for many mechanical and electrical applications, without the high cost and long lead times of hard tooling. Custom metal parts from .0005" thick and up are produced with intricate patterns, precise tolerances and burr-free edges, in addition to exact repeatability. By combining photo etching for blanking with inexpensive or universal tooling for forming, Tech-Etch produces complex designs and shapes.

 | Cross roller ring can swing the loads
Because it has orthogonally arranged cylindrical rollers, the cross roller ring from THK is a roller bearing with high rotation accuracy capable of bearing loads in every direction. Cylindrical rollers are arranged with each roller perpendicular to the adjacent roller, in a 90-deg V groove, separated from each other by a spacer retainer. This design allows just one bearing to receive loads in all directions including radial, axial, and moment loads. This component is optimal for applications such as joints and swiveling units of industrial robots, swiveling tables of machining centers, rotary units of manipulators, precision rotary tables, medical equipment, measuring instruments, and IC manufacturing machines. Available in several rotation configurations including inner/outer ring, inner ring only, and outer ring only. And now a new micro cross roller ring is perfect to handle smaller applications.

 | 12 principles of modern military leadership: Part 2
Leadership is paramount to the success of any army -- and any organization in general. Leaders not only make life and death decisions sometimes, but directly control the climate and quality of life of their subordinates. But what is the real definition of leadership? Capt. Ron Roberts of the U.S. Army's Asymmetric Warfare Group discusses 12 fundamental leadership principles, as well as several educational and inspirational historical examples. How much do they apply to what you do?

 | Laminating precision parts with polyimide film for insulation and spacing
When a dielectric is required to maintain accurate finger spacing or for insulation, Tech-Etch can laminate materials such as polyimide. Polyimide can be die-cut and directly bonded in place or full sheet laminated and then photo etched for extremely accurate positioning. Parts can be formed after lamination. Tech-Etch also photo etches polyimide film into flat parts including non-conductive washers, screens, gaskets, insulation layers, and liners. For flexible circuits, the coverlay is the insulating layer of polyimide placed over the exposed conductors. Polyimide is ideal for corrosive environments and also exhibits excellent physical, chemical, and electrical properties over a wide temperature range. Tech-Etch offers complete prototype-to-production facilities for etching extremely intricate parts.

 | Replace traditional fasteners: 50+ retaining ring applications
The benefits of a Rotor Clip Retaining Ring are simple: The ring is made from less material than traditional fasteners, eliminating machined shoulders, threads, cover plates, and heat-formed studs -- so you save. Using a retaining ring to fasten your assembly instead of a traditional fastener not only reduces your costs, but also saves the environment. Fewer parts and less material means cost savings for you and less waste for the planet. This quality part offers lot traceability. Want to know what you can do with a Rotor Clip Retaining Ring?

 | Collect and understand vibration condition data
Vibration monitoring is one of the most effective ways to detect potential equipment failures before they cause downtime. However, vibration analysis is complex, and it can be cost prohibitive to place sensors on noncritical assets. The new, wireless Fluke 3561 FC Vibration Sensor allows maintenance teams to improve uptime by adding remote, continuous vibration monitoring to virtually any rotating equipment. With a frequency range of 10 to 1,000 hertz, the 3561 FC detects and notifies users of conditional changes caused by critical faults like imbalance, misalignment, looseness, and bearing wear, providing warning of impending equipment failure.
