    You mean 4kw direct drive spindles? Or belt driven BT and similar by 4kw motor?

    Cause if first i dont see a reason why not to go with 4kw water cooled spindle. less than 400$ now that you have the drive. Bearings are cheap to change one day. What would bring the more expensive ones to the table that the Chinese one can not do??? for 1/5th or 1/10th the money?

    But if i was to make it BT30 driven i dont see any option save servo driven. Why to put so much money and effort and not be able to do rigid tapping and similar??
