Know Your High Flex Cable (.pdf)
When your application calls for cable meant to stand the tests of time and motion, you need to know what to purchase and what constitutes product quality. Cable designed to survive 10 million to 20 million flexing cycles is high-flex-life cable. It's different from high-flex cable, which

High-performance gear reducers keep pace with latest servomotors
Modern ac servomotors built with high-energy density, rare-earth magnets, and powered by sophisticated controls, produce significantly higher torque at higher speeds than conventional models. Because there are more gear teeth in mesh, planetary gear reducers, for a given ratio and volume, have

Towards the Single Pump Solution - Recent Development in High Speed Machines for Dry Vacuum Pumping (.pdf)
The goal of a single _dry_ pump capable of reaching high vacuum and itself exhausting to atmospheric pressure has long existed in the vacuum field. The development of a single-shaft, high-speed pump EPX _second generation_ mechanism has gone some considerable way to achieving this goal. The pump

Leadscrews roll over ball screws
are high helix, fast leads (greater than 100 mm/rev) with threads as small as 0.5 mm/rev. Plus, nonbackdriving, self-locking leads and multifunction nuts are easily customized, and can offer zero backlash with light preload and low drag. Leadscrews differ from ball screws in that they use sliding rather

What You Ought To Know About Ball Screws
to transport wafers for processing and inspection. The elevators also connect to robotic wafer arms or move wafers into furnaces. High-helix single nut arrangements achieve high travel rates with minimum rpms. High-helix double nuts provide additional capacity and load redundancy compared

Leadscrews roll
20 to 25 mm come in lengths over 4 m, virtually impossible for a ball screw. Thread grinding cannot produce these high-helix leads and the cost of a 4-m-long ground screw is prohibitive. Yet the best leadscrews are produced in many leads with standard accuracy of 0.6 m/mm and special accuracy

A New "Twist" On Nanostructures
to that used for nanobelts and nanosprings makes nanohelices. Zinc-oxide powder goes inside an alumina tube, which itself goes in a horizontal high-temperature tube furnace. The furnace heats the material under vacuum to about 1,000 C, at which point an argon carrier gas is introduced. Heating
