Before you dismantle a high speed spindle, be aware that some are balanced after assembly. I have a nice 3hp 18,000 rpm air-cooled Elte spindle. I had the idea of removing the fan and replacing it with something quieter that is thermostatically controlled, since I use it mostly for engraving. I called up a stateside distributor and their tech guy told me that the company bolts the fan in place, then balanced the entire rotating assembly _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
