New to me, and has very low hours, consider it new! Seriously - I don't think it has ten hours of spindle on time. It is that clean, I need to look but trust me - its mint!
We came by this machine when the owner lightly crashed it and decided there is more to machining than he thought, PHD with deep pockets.
People with GEDs can run them, how hard can it be?
So seriously... I have never run a Haas lathe and I am struggling with a second opp with bored soft jaws to get the parts true. But a lathe is a lathe and an easily deflected spindle is bad - I can't do this on our Hardinge or Monarch.
Cut to the end - I set a 0.0001" Indicator on the tool post, touching side of chuck. With a 1.250" steel bar stock 8" from chuck jaw face.
Palm of hand on end, elbow on hip I can deflect the chuck 0.0004" pull back 0.0002". Total of 0.0006" agreed?
Using a bathroom scale against the concrete wall I can get just about 80 lbs pushing. No idea on pull but I imagine it less.
Tell me this is wrong please. We are contacting Haas for a service call. Any experience to share?
