How can I verify if a spindle is manufactured by Westwind?
Over the years Westwind has developed an extensive range of
spindles for PCB manufacturing, automotive coating,
semiconductor manufacturing equipment,  scanning, lens turning,
and grinding applications.  Westwind spindles are commonly
found on Excellon, Pluritec, ESI (Dynamotion), Lenz, Posalux,
Schmoll, Hitachi, Fanuc, Durr, Agfa, Creo, Heildberg, Eskro, and
Federal Mogul machines.

Westwind spindle models are typically labeled on the body with
four digits followed by two digits to indicate the option number.
(e.g. D1331-54)

How much does a repair cost?
The amount a repair costs depends on the number of parts that
are damaged and need to be replaced.  When comparing repair
facilities keep in mind that the cost also depends on the quality of
the parts used in the repair.  Our objective is to provide a repair of
the highest quality to meet or exceed original design
specifications.  In other words, to return your spindle to like “new”
condition.  Over the long term this is the most cost effective
method to service your spindles.  

What are the consequences of  using low quality parts versus  
O.E.M. certified parts?
Reduced spindle life which leads to frequent repairs which cause
increased costs and reduced productivity.
