As far as I am aware the ER collet receptacle is always integral to the spindle. 3,000 to 10,000 seems to be a somewhat awkward range, being rather faster than a standard induction motor and rather slower than the generic high speed spindles. If you look at the ER32 eBay spindles those seem to top-put at 18K. The listings generally say "0 to 18,000" but I suspect that isn't quite true. I have used my 24k spindle at 6k. That leads me to think that an 18k one might be OK at 4K. Is your application high or low torque? Maybe the answer is a standard induction motor and belt drive? -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
