a gearbox to cope with 20k, i'll give Lewis or Jensen a ring i'm sure they'll have one spare.

Why they only go backwards. . . . . . . . . Even Lewis whinged about it off start at weekend.! . . . . Anyway I've got a spare motoX gearbox that can just about handle 20K if your stuck. Lol

DMM you can have a full 4 axis set 1000W motors and drives BOB, PSU,cables etc for $1600.!!. . .Not exactly comparing apples with apples due to lower RPM but still good price.

Yep you are right and with free shipping thats a real good deal... Im still trying to find a low profile motor with enough power to gear up and down around 6k and im not having any luck.. it looks like im going to get my atc but i will onle be able to draw pictures with the machine.... in ten colours of course..

For that amount of money I'd want to be getting more than 12000rpm. 18000rpm would be much better, but it seems toolholders which are sufficiently well balanced for that speed are rare and expensive.

This lot look worth investigating:

In particular the first one - 1130-24Z or 1130-16Z. The 24Z (24krpm) has 35mm bore bearings, but the 16Z (18krpm) has 40mm bore thin section bearings. Need to investigate which is strongest. The one you have a quote for uses 45mm bore bearings, so it would be more rigid, but any of these will be more than the standard 2.2kw ER20 spindles which only use 25mm bearings. If they can't wind the -24Z for 220V then it'll have to be the 16Z spindle anyway.
