Guys
Can anyone with first-hand experience on an ST20 with the BMT-65 turret tell me a little bit about accuracy and rigidity?
If you use an ST20Y or SY, I am still interested in your responses regarding rigidity.
Will likely be pulling a trigger on an 8" lathe within the next month or so, and so far the ST20 with the BT65 turret is the only contender.
I am looking for a plane-jane 2 axis lathe with tailstock.
No bells, no whistles, no milling, no chip conveyor, just a lathe with tailstock and toolsetter.
The #1 issue I am not willing to compromise on under any circumstance: chuck-turret clearance!
I will NOT! consider any machine that cannot clear adjacent tools with the 8" chuck.
I will NOT! remove an unused ID tool tool from the turret just because it would be busted off by the chuck.
Unfortunately, that one criteria knocks out 99% of all possible candidates that I know of.
Thankfully, Haas offers the BMT65 without the motor as an option.
There is no live tool or anything, it is just a substantially larger turret that provides the tool clearance I require.
Problem?:: It is a Haas!
With that larger turret, I am absolutely concerned about loss of rigidity and accuracy!
And before anyone starts banging on Haas, please, just don't!!!
I have 2 of their lathes, one is 21 years old, the other is 18, and both will absolutely hold a .001 total on anything, one will hold .0005 total on Inco.
All I need to know is if there is anyone that can shed some light on what I can expect?
Thank You
