Motorized rotary stages
AGR series motorized rotary stages by Aerotech provide a worm-gear-drive designed for positioning in industrial and labortory use with a stage base that can be used in multi-axis arrangements and other weight critical options.
AGR series motorized rotary stages by Aerotech delivers a worm-gear-drive that is designed for a wide range of applications including general purpose positioning in laboratory and industrial uses. The AGR series provides accuracy to 20 arc seconds, with 8 arc seconds bi-directional repeatability, 30 rpm maximum speed, and 360° continuous or optional limited travels. Tilt error motion is 10 arc seconds, axial error motion is 5 µm, radial error motion is 10 µm and maximum axial load is to 425 kg.
Apertures are available from 50 to 200 mm diameter. This feature allows the AGR series to address applications requiring a through-hole or accommodations to mount an optic, including articulation of beam polarizing lenses, through-holes for cabling and/or air lines, or vision/camera/inspection applications.
The AGR stage base is fabricated from an aluminum alloy that makes it useful in multi-axis arrangements and other weight critical options. Each stage is designed with two high-precision angular contact bearings with optimal spacing for error motions coupled with high load capacities.
Options include brush, brushless and stepper motor selections as well as a direct encoder mounted to the stage shaft for outstanding repeatability and to virtually eliminate hysteresis and backlash. The series includes vacuum-compatible versions for use in pressures as low as 10-6 torr.

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
