(September 2019, Arvada, CO, USA) For nearly 20 years, ALIO Industries has provided the most accurate and repeatable motion control solutions available in the market today. The company’s focus is entirely on nanometer-level precision motion and the development of products, manufacturing techniques, and IP for 6-D Nano Precision®. The company does not build legacy products, and also understands the 6-dimensional errors associated with simple linear motion. All ALIO’s products are designed with negation of these errors being of paramount importance.
So saying, the company has introduced the concept of Point Precision® which has now been adopted by NIST as the future standard methodology of measuring and quantifying motion systems. Point Precision® includes all 6 degrees of freedom of errors of each axis in motion, guaranteeing the precision point in the full work envelop. Point Precision® allows for a “precision number” to be quoted based on an exact point and is a must for many applications from laser processing to metrology.
ALIO manufacturers a range of linear motion control solutions that are designed and manufactured to standards that ensure their market-leading performance and reliability. The company’s mechanical bearing stages can perform at a level of precision that cannot be replicated by any air bearing stages. This is because ALIO focuses on 6-D Nano Precision® while alternative suppliers design and build to the 2-D world of planar repeatability and accuracy.
The family of ALIO linear stages exhibit world-class performance, customers able to chose from a variety of components such as different motors and encoders for demanding applications or to adhere to strict costs sensitivities.
PRECISION CROSSED ROLLER BEARING LINEAR STAGES
ALIO’s Nano Precision XY Monolithic product is a 3-plate system with unmatched 6-D performance. With year’s of testing, continually improving designs, and unique manufacturing protocols, ALIO’s precision crossed roller bearing stages have no equal for quality and performance, and range from 25-400 mm of travel with motor and encoder options available for specific customer applications.
XY LINEAR SYSTEM
ALIO’s XY monolithic True Nano® motion systems exhibits unequalled 6-D Nano Precision®. With nanometer-level straightness and flatness, customers can be guaranteed that point precision is True Nano®. This stage family comes with enclosed or open center versions from 50-450mm travel. Standard axis bi-directional repeatability is less than 40 nanometers with optional 10 nanometers bi-directional repeatability for demanding metrology or manufacturing requirements. Stages can be provided with NIST traceable data assuring nano precision, not just marketing data sheet optimism.
SERVO VOICE COIL Z STAGE
Precision and compact designs for Z / lift stages have been an industry challenge for which ALIO has engineered a solution. Legacy designs such as wedges are compact, but lack sub-micron precision in all 6-degrees of freedom, and linear stages with counterbalances take up space as well as making application tooling a challenge as they need to be designed around. The ALIO nano-precision, air counter balanced Z-lift stages solves this with voice coils (VC) and rigid precision structures that have application mounting locations on all sides of the precision rectangular structure. ALIO VC stages are available up to 50 mm of travel with nano precision designs and compact counterbalancing. Customized solutions with longer travels can be made for specific applications.
LINEAR CM SERVO MOTOR
ALIO has a family of CM linear servo stages for customers that require less costly True Nano® precision. CM servo motor stages still have ALIO 6-D precision with less linear force for smaller and lower acceleration applications. The stage family uses the same precision anti-skid bearings that are included in all ALIO mechanical bearing products with the same 25-400 mm travel ranges.
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.
