Thoughts on this setup? (1.5kw Spindle + VFD)

[Doddy]

Hate to reply because if you get a dud it looks bad. BUT... the Chinese water cooled spindles, and a Huanyang VFD are the staple for most builds here, and many a machine you'll find on the market. They're covered in Chinglish marketing speak (sometimes the claim of 4 German bearings is a little optimistic... sometimes not), but they generally work well. Nice a quiet, and usually low run-out on them. Cock all power below 6krpm, but above that they perform well.

I can't help but think, however, for the same cash (or less) you'll find a 2.2kW one - you claim you don't need the power, or the larger ER20 collet. Until you do.

They're a good buy. Provided they work :)

Agree with Doddy 100% on the quality and the above statement, I've literally fit 100's of these spindles and the slight diffence in weight isn't worth the saving, the ER20 collet size gives you so much more scope and the extra power you will be thankful for when cutting aluminium with a decent depth of cut. You don't want to be scratching alumnium away as it just kills tools and gives a shitty finish.
