Stages

Optimal Engineering Systems (Van Nuys, CA) released low-profile XYθ (theta) stages that move in an XY-plane and rotate around the center of the XY-plane. Available in 12 models in two precision grades, the stages have linear travels from ±2 by ±2 mm, up to ±30 by ±30 mm. The stages can rotate around the center of the XY plane up to ±6°. Four models have solid tables sized from 100 x 100 mm to 200 x 200 mm, and eight stages from 250 x 250 mm to 1500 x 1500 mm are hollow core (open frame) stages. Available in normal and precision grades, they have preloaded cross roller bearings, and typical normal repeated positioning accuracy is from ±1.75 μm to ±2.5 μm; typical precision repeated positioning accuracy is from ±0.7 μm to ±1.0 μm. Parallelism of the stages is as low as 30 μm, and the larger stages can handle dynamic loads to 600 kg. The stages can be ordered with linear encoders for closed loop operation, customized to meet specific requirements, and complete ready-to-run alignment systems.

Nanopositioning Stages

Aerotech (Pittsburgh, PA) offers the QNP-XY series piezo nanopositioning stages with resolution to 0.15 nm, linearity to 0.007%, and repeatability to 2 nm. The stages provide a variety of travel lengths (100 μm to 600 μm), feedback options, and vacuum versions, as well as resonant frequency up to 885 Hz. The capacitive sensors measure the output of the positioning carriage directly. The stages are available with capacitance sensor feedback or without feedback (open-loop). Open-loop provides an option for applications where compact size, high dynamics, and subnanometer positioning resolution are required, but absolute positioning accuracy and repeatability are not required. Open-loop designs can also be used where the piezo position is controlled via an external feedback source (interferometer, vision system, photodetector, etc.).

Coupling

C-Flex Bearing Co. (Frankfort, NY) offers a Super Plastic torsional damping coupling that stabilizes high-precision systems by dampening transient torque variations. The patented design offers high-torque loads with zero backlash for positioning in industries such as medical, packaging, and semiconductor. The standard flexible coupling is made up of two high-strength aluminum ends with glass-impregnated polyamide flexures. They are available with both set screws and “No Mark” steel clamp bushings. English and metric versions are available. Bore sizes range from 0.125" to 1.25", and 4 mm to 32 mm. Lattice and servo styles are available in both the Super Plastic and all stainless steel versions.

Positioning Assemblies

UniSlide assemblies from Velmex (Bloomfield, NY) deliver movement in one, two, or three dimensions with linear motion. The systems also can be customized for specific requirements. They are compact, and the design allows for construction of multi-axis systems. They are available in an array of standard manual or motor-driven models and sizes, including linear assemblies, elevating tables, and XY tables. They can be customized with rapid/fine motion, thumbscrew locks, special finishes, way covers, revolution counters, position encoders, or other options. The assemblies are constructed of a hard aluminum alloy and PTFE bearings. Linear UniSlides have a maximum load capacity up to 400 pounds horizontally, and 100 pounds vertically. Straight-line accuracy with precision lead screws is 0.0015" per 10" or better of the screw motion. The elevating tables and XY tables can lift up to 100 pounds.
