Westwind recommend the use of distilled water with the addition of chemical agents to prevent algae or bacterial growth. Each spindle needs an uninterrupted flow at between 16-20ºC. Many spindles used in production are fitted with temperature sensors that shut the machine down before damage is done.

By clean air we mean the supply should be filtered to better than 0.01 microns and 99.99% free from oil and water as a liquid or vapour with a PDP (Pressure Dew Point) @ 7°C. Westwind are able to supply suitable filter units. Please note that in all cases we strongly recommend that the compressor system is backed up by a reservoir tank to maintain a steady pressure and to minimise the effects of an air failure.

Westwind spindles, when correctly installed and supplied with clean adequately filtered air, give many years’ service with the minimum of attention. Routine maintenance is limited to changing the air filter elements so that the air supply remains uncontaminated. Guidelines can be found online for spindle and collet maintenance.

No, you do not need to add lubricating oil to the air supply of the air bearing spindle.  This does not work like a ball bearing spindle. You should not add oil, as air bearings, being non-contacting, do not need a fluid lubricant.

Most Westwind air bearing spindles are fitted with integrated asynchronous AC squirrel-cage electric motors. However, some more specialized spindles, especially for advanced material processing applications, are fitted with integrated brushless DC motors.  Currently, all Westwind atomizer spindles are driven by integrated air turbine motors. Learn more about our Coating Atomizer Series Spindles here.

For all high speed Westwind air bearing spindles, it is necessary to fit a motor controller between the spindle and the main supply, as frequency and voltage controls are necessary to rotate the shaft at the correct speed. These drives create very high frequency outputs from the main input frequency of 50 or 60 Hz.

Yes, most Westwind spindles are fitted with a speed sensor to facilitate shaft speed measurement.

The Westwind product line spare parts are manufactured to the same high quality and tolerances as our spindles (Westwind product line is ISO 9001:2015 registered). Our manufactured collets are specifically designed to operate at the high rotational speeds and dynamic run-out accuracy demanded by our customers. Alternative components cannot only reduce the life of the spindle, but may also affect product quality and output. Experience has shown that by fitting only genuine Westwind replacement parts, the high productivity, consistent accuracy, and outstanding operating characteristics can be maintained.

It is likely that contamination over a period of time has prevented the shaft from floating freely. We strongly recommend the unit be returned to your local Westwind product service centre for investigation.

This should be carried out at intervals recommended by the machine manufacturer. You are strongly advised to refer to the appropriate Westwind collet maintenance booklet (available free on request), and to use the Westwind collet maintenance kit available through your machine supplier. However, as a general rule we would recommend a maximum of 5,000 hours between removal/cleaning/re-setting, although some end users maintain their collets every 100 hours.

    PCB Drilling and Routing

    Spindles with Vast Speed Ranges for Increased Productivity

    Ideally suited for the high speeds required of drilling extremely small holes in PCB materials, typically down to 0.1 mm diameter, while still delivering sufficient power at low speeds to drill 6.3 mm tooling holes.

    The PCB Drilling & Routing Series Spindles deliver smooth, precise rotation that enables maximum tool life and excellent hole quality. Very low runout ensures accurate hole placement. Integrated non-contact axial and radial air bearings guarantee long service life with minimal maintenance and very low heat generation. Highly reliable water-cooled AC induction motors are fitted into every spindle. Mature design based on extensive experience and expertise, accompanied with state-of-the-art manufacturing, enables reliable operation and long product life.
