“Lots of questions. In a nutshell: I’d like an air-cooled unit that does an excellent job on medium-duty hobby woodworking and can be serviced in the US. Quality of unit and quality of work are more important than cost.”
Did you try CNC Depot ?
I don’t know if they offer air cooler spindles but they say their spindle are made here. Here si the response I got to my query on Oct 6, 2021.
Bob,
We manufacture all the parts for our spindles in Tennessee, USA except for the motor components and the bearings. We have multiple vendors for our motor components in Brazil, South Korea and others, and our bearings are primarily manufactured in Germany.
Please let me know if you have any other questions.
