Hyundai WIA experience ?

[MrFish]

Anyone have any experience with Hyundai WIA machine tools, good and bad ?

specifically the XF6300 and XF2000i

Last place I worked at had a KF5600 with the mold package.  It's a pretty well built machine from what I remember.  The integral spindle was super nice as well.

Hmmmm...."integral spindle"....having been very badly bitten 20+ years ago with Hitachi machines, which all had integral spindles, when they need a rebuild it is mega-expensive.

I really don't think you can beat a direct drive spindle with coupling - thinking Robodrill, Matsuura's, even my 15k rpm Feeler machines had that. Really simple and IMHO, technically far superior to keep the motor (many KW = heat) well away from the spindle bearings....

Oh I don't doubt they're stupid expensive to replace.  As far as growth and such it was pretty damn stable.  Was an excellent machine for super tight mold work.
