This is my first thread here so by the way i would like to say hello.
As for main topic... there are many threads about chinese water cooled 2.2kW spindle but i can't find any information about high power ones. By high power i mean for example 3 kW, 4,5 kW or 5,5 kW, powered from 3-phase 380V.

Nobody is using them ? Too expensive ? Bad accuracy ?
I'm making a first steel gantry CNC machine, mostly for aluminium milling and learning. Working field 800 x 600 x ~240mm. Even though the frame is not ready yet, i'm looking for spindle solution. First i thought of HSD but i started thinking - for half the price, even with tax fees, i could get the same or similar power which for home / hobby / learning usage will be more than enough.
Any advice's ?
