Ultra-Precise Positioning Achieved with Zero-Backlash Rack & Pinion Drives from ATLANTA Drive Systems
 ATLANTA Drive Systems, Inc. offers a range of zero-backlash rack & pinion drives that eliminate system backlash by means of a split-pinion and dual-pinion arrangement, providing ultra-precise positioning and repeatability. Positioning accuracy is maintained during acceleration and deceleration, as well as for direction of travel reversals. The backlash is eliminated by using two pinions - one to drive the axis and the other to engage the opposite tooth flank and take up the backlash. Mechanically preloaded split-pinion drives utilize an axial spring to load one pinion half against the other. Electrically preloaded dual-pinion drives utilize two motors, each driving one pinion, which are loaded against each other by means of a special motor controller. ...More >>White Paper: Nano-Scale Imaging Fabrication Advances Driven by Piezoelectric Active Vibration Control  Abstract Engineers from TMC and PI have developed active vibration isolation technology based on piezo ceramic solid state actuators that has become an established solution in nano-lithography applications. However, active vibration cancellation can also improve stability and resolution in super-resolution microscopy applications. Based on digital signal processing algorithms and responsive PI piezo technology with the latest ultra-reliability enhancements, patented STACIS active isolators have proven their dependability in mission-critical fab deployment for over a decade. STACIS is now available in small form-factors ideal for emerging applications ranging from advanced microscopies to nanomanufacturing. ...More >>Sherborne Sensors Announces the AccuStar Electronic Clinometer  Sherborne Sensors a global leader in the design, development and manufacture of inclinometers, accelerometers, force transducers, load cells, rotary encoders, instrumentation and accessories for industrial, military and aerospace customers, has announced the AccuStar® electronic clinometer, designed to provide precision angular measurements within applications where a high degree of accuracy is required.The unique design of the AccuStar® incorporates a capacitance-based sensor without moving parts. ...More >> LCA Series is the next Generation of Moving Coil Actuators by SMAC  SMAC Inc. has developed next generation moving coil actuator LCA series designed to replace pneumatic cylinders with an expected 10 times improvement in cycle life over pneumatics and a competitive list price starting at $500.The first model in this series, the LCA25, has a small overall footprint 25mm (H) x 50mm (W) and length depending on stroke. Starting with stroke length of 10mm, the range will extend up to 100mm with encoder resolutions from 20micron to 50nanometer. ...More >> The American Society for Precision Engineering (ASPE) will hold a tutorial on Industrial Motion Control  Cambridge, MA - The American Society for Precision Engineering (ASPE) will hold a tutorial on Industrial Motion Control to open their spring meeting on the Control of Precision Systems, April 11th, at the Massachusetts Institute of Technology in Cambridge, MA. In this tutorial the students will be able to understand and refresh the main aspects in the application of motion control for precision systems. From the broad field of control theory, those fields most often used in industry will be introduced, explained, and applied. This focus will help engineers from different backgrounds to be familiar with the terminology and meaning of the most common theories.

Special 2" All Stainless Linear Motion System from LM76 East Longmeadow, MA - We do not believe any company has ever manufactured a completely stainless 2" linear system before. LM76 did it from Scratch! Our customer is a world-renowned manufacturer of all stainless systems that process nuclear medicines. Since these systems are radioactive, all management of the system must be accomplished remotely. During the process, materials move from section to section through stainless steel doors which slide on LM76 all stainless linear bearings and shafting ...More >> M122 Miniature Linear Stage by PI provides 1 Inch Travel  The M-122 palm-top-sized precision translation stage from nanopositioning systems specialist PI (Physik Instrumente) L.P. combines compact dimensions, high dynamics & speed and very high accuracy at a competitive price.Due to its low-friction, the backlash-free ball screw yields significantly higher mechanical efficiency than leadscrews, and allows maintenance-free, high duty-cycle operation at high velocities -- up to 20 mm/sec. ...More >> Low-Cost Drive Electronics for Piezo Linear Drives from PI The compact NEXACT piezo stepping drives from Physik Instrumente (PI) push forward into a new performance class for linear drives: with high forces of 10 N, velocities of more than 10 mm/s, and at resolutions of a few nanometers they replace the typical stepper or DC servomotors in applications that depend on the combination of force and resolution on large travel ranges. The E-862 driver electronics is the ideal control for the NEXACT drives when operated in open-loop or when used with an external positioning and velocity control. By using an analog input signal, the driver can be connected with external motion controllers or it can be controlled directly by using a joystick. ...More >> iC NQC has 13 bit real time interpolation now with BiSS C for uninterrupted absolute encoder measurement  For the first time ever high-resolution sine-to-digital converter iC-NQC provides the microelectronics industry with a BiSS C slave protocol that enables bidirectional data exchange at the same time as the cyclic output of measurement data. Normalized addresses device information is available that indexes the relevant standard device profile or a description file. An optional electronic ID plate can also be used to describe the measurement application.
