Aerostatic bearing technology and manufacturing capabilities of Air Bearings Limited / ABL

Established in 1993 in the United Kingdom, Air Bearings Limited (ABL) operates as a world-leading developer and manufacturer of high-precision aerostatic spindle systems.

Located in Ferndown within the county of Dorset, the dedicated manufacturing complex brings together specialized engineering teams covering computational fluid dynamics, precision CNC tooling, and sub-micron grinding.

Over 90 percent of the complete manufacturing lifecycle at Air Bearings Limited / ABL is performed in-house, ensuring stringent quality control over geometric tolerances and dynamic run-out.

ABL aerostatic spindles serve global electronic industries across high-density circuit board micro-drilling, semiconductor wafer slicing, and ultra-precision diamond machining.

High-speed multi-layer printed circuit board drilling with ABL AW series spindles

Modern microelectronics and high-density interconnect board fabrication demand reliable drilling of micro-vias down to 0.1 mm diameter at rotational velocities up to 200,000 rpm.

The AW series spindles from Air Bearings Limited / ABL, including the AW080A, AW125A, AW160D, and AW200B models, are engineered specifically to satisfy these high-productivity demands.

Utilizing aerostatic air film suspension eliminates mechanical contact wear between sliding elements and reduces dynamic run-out to near-zero levels.

This extends carbide micro-drill tool life, eliminates bit fracture upon rapid workpiece contact, and delivers clean hole walls for dependable multi-layer circuit metallization.

Heavy-duty PCB routing and panel depaneling with the AW160D spindle

Board profiling and routing cycles exert continuous lateral cutting forces on the spindle rotor.

To endure these severe operational demands, Air Bearings Limited (ABL) developed the AW160D spindle, pairing rotational operational speeds up to 160,000 rpm with elevated aerostatic radial load carrying capacity.

The spindle housing incorporates a liquid cooling jacket and an active pneumatic labyrinth barrier with continuous positive air pressure.

This air purge curtain prevents abrasive glass-fiber dust and copper particles from entering the bearing clearance gap, providing long-term reliability throughout continuous industrial shifts.

Ultra-precision micro-machining and diamond turning with MM series spindles

In micro-milling optical mirrors, microfluidic devices, and precision mold inserts, maintaining exact tool tip trajectory is paramount.

The MM series spindles from Air Bearings Limited / ABL, including the MM080A, MM125A, and MM160B models, provide rotational speeds up to 160,000 rpm with total radial and axial synchronous run-out under 0.05 microns.

Driven by brushless synchronous motors and surrounded by stator cooling channels, MM spindles maintain thermal equilibrium throughout prolonged machining cycles.

The minimal thermal drift enables sub-micron coordinate micro-milling of non-ferrous metals to produce mirror-like surface finishes without secondary polishing operations.

Optical lens grinding with LGS10A and wafer slicing with DS060E spindles

For ophthalmic and semiconductor industries, Air Bearings Limited (ABL) manufactures the specialized LGS10A and DS060E spindle units.

The LGS10A model is tailored for grinding toric and aspheric contact lenses, where aerostatic cushion damping prevents micro-vibrations from degrading optical curvature clarity.

The DS060E spindle is dedicated to high-accuracy slicing and dicing of semiconductor silicon wafers, quartz substrates, and optical crystals up to 60,000 rpm.

Its rigid shaft arbor supports 2-inch and 3-inch dicing wheels, while internal deionized fluid ports deliver direct blade cooling to ensure chip-free kerfs.

Compressed air filtration standards and preventative maintenance for ABL spindles

The precision and operational longevity of Air Bearings Limited / ABL spindles depend upon clean, dry compressed air.

Supply air must strictly comply with ISO 8573-1 Class 1 standards for residual moisture, oil aerosol, and particulate content, because bearing gaps operate with single-digit micron clearances.

Air delivery systems must incorporate coalescing filtration stages and refrigerated or desiccant air dryers before connecting to the spindle manifold.

Maintaining positive air pressure prior to motor activation and using balanced ABL collets avoids dynamic unbalance and preserves spindle bearing longevity.
