Heason Technology is introducing the Dover AirGlide ultra-precise air bearing system. With positional accuracy to within 3 microns for the standard version and better than 1 micron for the interferometer-calibrated version, the AirGlide has a bidirectional repeatability of +/-0.3 microns over a travel range of up to 1000mm. The high-stiffness, ultra-smooth bearing system has a space-saving shuttle design that features a high-speed linear brushless servomotor that suits precise velocity scanning as well as nanometre-level step-and-repeat applications in high-throughput production systems or research equipment.
A choice of sub-micron or nanometre-resolution encoders in single-axis or XY configurations from 150mm to 1000mm travel are available. AirGlide's impressive standard specifications include an acceleration capability to 5m/s2, maximum velocity of 1m/s and loads up to 40kg. These application-dependant values may be increased and can be adapted for specific customer requirements with Heason and Dover engineering support teams available to assist customers from initial design through to commissioning and beyond.
AirGlide includes a high-flex cable management system with standardised termination connectors for simplified integration. Options include low-profile Z-theta assemblies in complementary precision grades and wafer vacuum chucks. Additional signal and air lines can be routed to the top plate, and customised interfacing fixture plates and complete granite machine bed and frame systems can also be provided.
AirGlide's bearing system uses Dover's innovative clog-free technology that is claimed to provide superior reliability while eliminating many costly filtration components, and the non-contacting bearing and motor system combines for almost limitless life with extremely low maintenance.
Dover has a 40-year history in air bearing system design, with applications across semiconductor, life sciences, medical instrumentation and metrology, as well as technologies such as flat panel display and solar panel production. The decision to appoint Heason as the exclusive UK distribution partner follows a long and successful history with the product line, which includes the former NEAT (New England Affiliated Technologies) range of positioning mechanics that are now manufactured under the Dover banner. The decision also reflects Heason Technology's recent appointment of Jason Breslin to head its technical sales team - a move that further signalled the Company's objective to augment its market position as a premier European designer and manufacturer of mechanical and electronics based motion control systems for manufacturing and research.
