Air-Bearing Spindles

ABTech offers air-bearing spindles from 1,000 RPM to 20,000 RPM for the most demanding machine tool and inspection applications. High load capacity and stiffness with low air consumption, dual-plane balanced to exceed the G0.4 specification and minimal radial asynchronous error motions make these spindles ideal for single point diamond turning, work holding, grinding, and polishing applications.

Mechanical Bearing Spindles

ABTech's mechanical spindles are superior in performance and quality. They are used in a wide range of applications where a combination of lower-cost & high-performance motion is required. mechanical spindles are ideal as stand-alone units and/or multi-axis assemblies, for optical scanning, machining and grinding, and more. By leveraging ABTech’s knowledge and experience gained in producing the extreme tolerances required for air bearings, our mechanical bearings achieve radial and axial error motion of < +/-20.0 µ” (+/-.50 micron).
