Tap Teflon for the Tougher Jobs
If your mechanical motion system is headed for abuse like heavy washdowns, total submersion, high chemical or contamination loads, or even steam pressure, self-lubricating Teflon bearings could help. These self-aligning, FDA and USDA compliant bearings handle up to 10x the load, dampen vibration, and tolerate shock better.

Thinner Bearings for Finer Precision
Suppliers broaden lines to meet a rising demand for precision. Thin-section bearings offer smooth, controlled movement for tight tolerance tasks like robotic joints, medical imaging, and satellite guidance. Lower profiles and super-finished raceways produce enhanced stiffness, and minimal torque, internal friction, and vibration.

Motion Control Steps Up Stone Cutting
Stonecutting's biggest challenge isn't cutting hard materials like marble or granite. The hardest job is maintaining high productivity and cutting precisely enough to conserve the valuable raw materials. One tool builder improved its combo rotary saw and abrasive waterjet cutter by integrating a remote I/O drive and control system.

Cool Tool Checks Temp at Safe Distance
Vendor Web sites post new products; one that boasts a 'Cool Stuff' section is rare. If last month's stocking stuffers were disappointing, check these goodies: surface prep pens, non-contact voltage detectors, self-fusing tape, and an infrared thermometer. The latter takes temp readings at a distance without direct surface contact.

Tips for Trimming, Threading Thermoplastics
Whatever your thermoplastic — PP, PVC, PB, PBD — it might be right for finished parts that can't be molded. But care is needed in high-speed, high-feed machining if right-sized parts with integrity are to result. This article provides tips and best practices for machining, milling, threading, and polishing low strength, brittle materials.

A New Spin on Microchips
Microchip technology being explored at UCLA could overcome barriers as transistors become smaller; especially problems from variations in material structure. Based on the spin of electrons, rather than movement of charged electrons, UCLA built a logic gate a few micrometers long to process the data carried by spin waves.

Photoetching Fabricates Fine Filters
Intricate filters like strain gauges, encoders, fuel filters, and electron grids, using photo-chemical machined screens yield more precise, burr-free parts. They also produce closer-tolerance hole sizes than stamping. Stainless steel screens can be straight or tapered hole for applications like liquid filtration and back-flow cleaning.

Piston Pump Saves the Sweets
Pumping hot, thick, and slightly abrasive liquids is extremely shear sensitive. Too much agitation from gear pumps can cause oil and butter separation. They often require specialty hardware — positive displacement circumferential piston pumps, with external timing gears to eliminate contact between rotating and stationary equipment.

Giving Back: Engineering Pearls of Wisdom
Through years in engineering, most of us absorb — often without realizing it — a professional wisdom that takes us beyond mere schooling basics. It is the wisdom that we employ in projects, in staff management, in career decisions, and more. Yet the lessons learned are seldom shared, at least widely enough. One mechanical engineer didn't want to retire after 44 years without sharing some pearls of wisdom. Among the advice he offers: listen to your supervisor, re-check your math, make the tough decisions, and don't quit your job before you have a new one.

Car to Lock in on Mach Plus
After death and taxes, there aren't many more 'givens' in life. Well, maybe one more. The next certainty: incessant pursuit of land speed records. This fall a UK team upped the ante unveiling plans to design the fastest car ever — one that can zoom 1,000 mph, or mach 1.4. Designers will push limits of computational fluid dynamics to study a phenomenon they call spray drag and reduce resistance at the sound barrier.
