True Nano® Precision Rotary Stages
ALIO Industries Posted 07/05/2019
Arvada, CO, USA - ALIO Industries is synonymous with best-in-class nanometer-level motion control solutions, and is well known as the only motion control technology supplier that offers true nanometer-level accuracy and repeatability.
Exemplifying the company’s grip on the ultra-precise motion control sector, ALIO Industries recently introduced its market-leading Hybrid Hexapod® technology, which out performs any other hexapod solution available to industry. The Hybrid Hexapod® is a game-changer in the field of motion control, and stimulates innovation as an enabler of next-generation manufacturing processes.
However, with upwards of 20 years working in the area of nanometer-level motion control, ALIO Industries has also developed TRUE NANO® precision rotary stages to meet and exceed today’s demand for high precision rotary motion. ALIO’s line of rotary stages continues to expand as the company works with each customer on a one-to-one basis to provide customized motion control solutions, not off-the-shelf mass motion control products.
Mechanical Rotary Stages
ALIO’s mechanical bearing rotary stages have been designed with crossed roller bearings for improved stiffness for offset loads and rotational precision. Integrated with servo torque frameless motors, these stages can handle applications where the mass and acceleration needs are extreme, while still maintaining nanometer-level precision performance.
ALIO’s focus on materials and machining is absolute in the manufacture of its rotary product line, just as it is with its linear products, ensuring the bearings and metal are located in ultra-machined parallel surfaces as shown by the machined lands on all stages.
Standard ALIO rotary stages have 0.2 arc-second repeatability using ALIO supplied motion controllers. Standard mechanical crossed roller bearings are rated at 13 to 20 microns of radial and axial run-out, with optional run-outs of certain models below 5 microns.
The mechanical bearing rotary stage family has multiple motor sizes to meet duty cycles as well as mass and acceleration needs from 80 mm to 300 mm in diameter. Vacuum rotary union options are available on the inner diameter for mounting a vacuum chuck.
Low Angle Mechanical Rotary Stages
ALIO has also designed mechanical bearing rotary stages with angular contact bearings representing the most compact design on the market. Integrated with servo ironless motors, these stages best fit metrology applications where small angular adjustment is needed with nanometer-level precision performance.
Air Bearing Rotational Stages
When ultra-tight run-out precision motion is needed, manufacturers can choose from ALIO’s continually growing line of air bearing rotary stages. Whether it is exceptional stiffness or cost-effective motion that is the priority, ALIO Industries can offer a variety of options to meet the needs of today’s nano-precision applications.
Dual Axis Rotary Systems
ALIO's two-axis systems are designed around the customers' mass with variable counterbalance, cable guidance, and cable and air feed-through capabilities. With hard-stops allowing for ± 110 and ± 170 degrees of rotation for nearly unlimited part access on the horizontal axis, ALIO’s dual axis rotary systems exhibit angular travel ± 180 for the rotation about the vertical axis.
Incorporating ALIO's industry-leading torque ratings, the company’s two-axis gimbal rotary systems are capable of high rotational speeds while maintaining the stand-out precision levels expected from ALIO Industries’ systems. Metrology, laser processing, additive manufacturing, and many other industry sectors have benefited from these ALIO products., and air purge is incorporated for contaminant protection and longer life. Internal cable and air line routing provide an extremely clean finished product.
AZ-EL Rotary Assembly
ALIO Industry’s AZ-EL rotary assembly systems also incorporate the company’s exceptional torque-ratings and are capable of high rotational speeds while maintaining the precision levels synonymous with any ALIO motion control systems. As with the two-axis gimbal system, the AZ-EL rotary assembly systems are used in metrology, laser processing, additive manufacturing, and numerous other industry applications.
Any company interested in ALIO’s nanometer-level motion control solutions are advised to contact the company, and discuss the ways in which bespoke solutions can be designed to precisely fit with specific application requirements.
