Hi,

A few questions:

1 - I want to use a 2.2kw water cooled Chinese spindle and gear it down 4:1 to an R8 spindle on a milling head I'm building.
The Chinese spindle can run at 20,000 RPM, so the R8 spindle would be 5000 RPM max.
Does anyone know of possible problems with that idea?

2 - Would it be possible to index and hold the R8 spindle in that indexed position using an encoder on the R8 spindle end?
Does the 2.2kw water cooled Chinese spindle have the ability to brake and hold a position?
If this could be done... how would it need to be wired and setup in Mach3?
Please explain any suggestions or problems with the above...

Thanks,
Ray
