Greetings,
I have decided to commence a project to build a CNC Benchtop Mill. I already have a Sieg manual mill that has an MT3 spindle, and I have a large amount of MT3 tooling.
When I buy the manual mill that will be the basis for the CNC Conversion, should I buy one with an MT3 spindle so that I can use the existing tooling that I already own (my current first preference), or should I buy a Mill with an R8 spindle ?
I've had some people advise me that an R8 spindle is far superior on a CNC Mill. Why - what makes R8 superior ?
Are there some disadvantages to using an MT3 spindle on a CNC Mill?
I hope some of the experienced people on this forum can advise.
Many thanks,
RoyG
