New high-precision, three-axis gimbal mounts with four motor options
OES (Optimal Engineering Systems, Inc.) has released four all new three-axis Azimuth, Angular Elevation, and Roll Gimbal Mounts. These new high-precision and high stability AU270-AER Gimbal Mounts locate the surface of the roll stage 115 mm below the center line of rotation allowing for the positioning of cameras, optics, lasers and instrumentation for scanning, tracking, […]
Multi-axis transfer robot features backlash-free belt drive
Bell-Everman has introduced a new multi-axis transfer robot based on its proven ServoBelt backlash-free belt drive technology. Called ServoBelt Arc Drive, it features custom designed rotary and tilt axes that precisely position semiconductor glass panels. Measuring 450-mm across, the robot’s large rotary axis is built around a ServoBelt drive mechanism and a proprietary Bell-Everman bearing […]
Elevator stages feature 0.03 micron resolution
Optimal Engineering Systems, Inc. (OES) has released two new motorized elevator stages, the DAG20-120-01 and the DAG20-120-04. These high-resolution, compact, low-profile elevator stages feature high stability 120 x 120 mm tables and 20 mm of vertical travel. High precision ball bearing profile rails assure high parallelism and smooth motion throughout the raising and lowering of […]
PI offers new stepper motor translation stages for precision automation
The new L-836 Stepper Motor Linear Slides from PI (Physik Instrumente) are a newly designed motorized linear translation stage family that combines high performance, small dimensions, and low cost of ownership. These compact micro-positioning translation stages are driven by a robust, direct-drive rotary stepper motor, available as in-line design and folded drive train design for […]
High-precision three-axis positioning stages feature four motor options
Four new three-axis stages from OES (Optimal Engineering Systems, Inc.) feature four different motor options to best fit application needs. The YPR-45-15-60 Series of three-axes stages were developed through the integration of a 60 mm diameter rotary stage (upper axis) capable of 360 degrees of continuous operation, and two goniometers (middle and lower axes) each […]
Aerotech launches second generation of nanopositioning stages
Aerotech Inc. has released the second generation of its popular ANT nanopositioning stages. Building on its best-in-class predecessor, this line is engineered to bring superior performance to applications that demand truly outstanding dynamics and nanometer-level precision. “We’ve made the ANT nanopositioning stages even better, giving our customers options with impressive dynamic capabilities, industry-leading positioning performance, […]
Comparing micropositioning and nanopositioning stages
Linear stage designs can range from long-stroke, high-load gantries to micropositioning and nanopositioning stages with light payloads. Although all linear stages are designed and constructed to provide high positioning accuracy and repeatability and to minimize angular and planar errors, stages for micropositioning and nanopositioning applications require additional considerations in component selection and design to achieve these […]
What are piezo flexure stages and how do they work?
Piezo actuators provide highly responsive, rapid movements, but their displacement is limited to just 0.1 to 0.2 percent of the actuator length. To overcome this limited stroke capability, a piezo actuator can be combined with elements, such as flexures, that provide mechanical amplification. The amplification provided by a flexure mechanism can extend the stroke of […]
What is a split bridge system and how does it differ from a gantry?
Multi-axis linear systems come in a variety of designs, with Cartesian, gantry, and XY tables being some of the most common types. While these designs simplify construction and can provide space savings, they also introduce “stacking” errors — the compounding of errors from each axis, which manifests at the work piece or tool point. Mounting axes […]
