Sieg KX3 Rigidity

Actually I measure on the column rather then the head stock, I think the problem comes with the loose gib at the most begining (hope so but not really), then I tigten it more and more and almost dead lock it but without the help, hence I have suspected the problem caused by the column. I am planing the simplest method to overcome it, bulid a brace fix at the top of column against the concrete wall just behide it, just don't know how well of the results ...will keep the post.

I have fixed the bracket top of the column finally, without the bracket it easy lean to forword for 0.1mm with about 20-30lbs applied on the head stock, now it reduce to 0.05mm even with 70-80lbs and reduce a lot chatter. Also I found the column casting extermly soft when I drill the holes on it, much more softer then the mild steel, maybe the root cause of the problem, of cause I know what you pay then what you get, I may no more complain when I have plenty of money to get a haas...

"add to cart"
looks to be a bit over my budget, better save up the lunch money

to contribute something useful instead of troll lol, at least with manual milling on the x3 i found a boring bar above off the top of my head (sorry didn't write it down) 500rpm to be unusable and very scary... the head would rock back and forth.

for those of you who have built a "cage" have you guys been able to take noticably deeper/faster passes with a good enough finish?
