September 3, 2019 - ALIO Industries has introduced the concept of Point Precision which has 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 used 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 performance. The company’s mechanical bearing stages can perform at a level of precision that cannot be replicated by any air bearing stages..
ALIO’s Nano Precision XY Monolithic product is a 3-plate system with unmatched 6-D performance. ALIO’s precision crossed roller bearing stages range from 25-400 mm of travel with motor and encoder options available for specific customer applications.
ALIO’s XY monolithic True Nano motion systems exhibits 6-D Nano Precision. With nanometer-level straightness and flatness, 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.
ALIO has a family of CM linear servo stages for customers that require 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 anti-skid bearings that are included in all ALIO mechanical bearing products with the same 25-400 mm travel ranges.
