Guys...
FYI.. I have owned/sold dozens of Chinese spindles from .8kw (1hp) to 3.7kw (5hp). I have been very fortunate, or lets say for the most part my customers have been, in that there has only been 1 failure that I am aware of.
Chinese watercooled spindles got a bad rap for the most part due to cooling failures. One, because the pumps are cheap. And two, and much more prevalent, is that the customers used the stupid water buckets and then let them fill up with sawdust. The pump eventually plugs, overheating the spindle which then blows up. Use a closed system with a radiator and an anti corrosion additive (not antifreeze) and you may run for years.
Are they as good as the US or Italian made spindle units? Maybe not. But any customer (or CNC mfgr) that would select a hand held router, made for occasional use instead of the lowest quality spindle is simply making a mistake.
