Thread: Haas lathe rigidity?

JDJ, sorry about the hyjack. But now I can say speak to the ST-Series


Started running 316L Hex today ...Curtis is right, much better then the SL series...at least rigidity wise. Tomorrow I'll start upping the Speeds and Feeds and see if we can cut the cycle time down.


Only Pain in the PooPer so far, is that the chips congregate in the front left corner.

And the safety crap...so far I can deal with everything except not being able to index the turret without jogging both axis first...then realizing I should have indexed twice so I need to jog again...then went the wrong direction and had to jog yet again...by the time I got to the right position...I forgot why I wanted to go there...


No answer from HFO on how to attach the Spindle Liner Guard, so we finagled it. Protected and no mess...

Yeah, how about that nice door safety lock that we hated. Can't say on here about how people unhook them from the door and just put the little fork in the switch and leave it except for start up. It would be unwise of me to talk of such. I was just told today about the fix for the spindle liner coolant mess. What they described to me looks like the cover in your pic. Should have mine next week. Not sure what you are describing exactly about having to jog before indexing?? Good luck with your new machine, hope you make a ton of money with it. I'm headed to the house for the weekend.

Yeah, that having to jog just to index the turret sounds absolutely retarded.

Sounds crazy!

???

..and what's that got to doo with "safety"?
Especially if you already jogged it to a safe index position the first time?


I had a Fanuc get all goofed up in the head yrs ago and had'ta send it out for an excorcism, and when returned had to reload all the params. Except - of course the params for my machine were mystically lost. So they sent me the params for the next serial numbered machine.

Apparently it was an EU destined machine and I koodn't doo Jack with the machine! Fortunately I knew how it should werk and I called the factory and we got some K bits changed around and life is fine now.
As long as "they" allow you some mobility for set-up with the door open - I actually LIKE the door switch on my lathes! I frequently will slip the door back an inch durring a turret index and that will automatically kill the coolant and put the machine in FEED HOLD all for free.

IMO too much "safety" features are unsafe b/c the machine has GOT to be usable, or nothing gits done/we go out of business. So in the end "werk-arounds" are used.


BTW - I should have sent that Fanuc to the Vatican as the excorcism still left a specter or two in there...


Not heard anything about rigidity of the Y axis machines yet....


--------------

I am Ox and I approve this h'yah post!

It's still new to me...so maybe I'm doing something wrong.

But for right now, I just need it pumping out parts so no time to play and figure it out.
I had thought maybe just Jog Home and all would be good...works for the 1st index only.


It's just a kick in the morning before the coffee kicks in, I feel like a Short Yellow Bus Candidate trying to index the turret to check out the tool tips.
Open door, close door, Jog X, Jog Z, Turret Forward, Open door, not yet...the lock didn't disengage, Open Door, Cannot see tool, close door, Turret Forward...nope jog X Jog Z..etc etc




I would never remove those two little Cap Screws securing the Locking Key in place....
So far it's really a non issue...except trying to adjust the Parts Catcher...which you cannot open the door anywho, locked or unlocked as Catcher interlocks with door....or so it seems. So yo have to open the side cover panel and look in thru there to see if Catcher and Chuck have clearance...again...watching me do that would guarantee me a seat on me Short Bus.

But all in all, I am liking the machine.

I'd be interested in seeing the Y axis at work...lots of room in there...compared to an SL.

This is somewhat subjective. But as others have asked, "compared to what?"

Haas is an inexpensive machine. It is "ok" for what it is. But if you're looking for rigidity, there are others.

I'm currently working for Doosan (formerly Daewoo), and their lathes are extraordinarily rigid. There are plenty of others out there that are good, too.

It's sort of like the old hot rod axiom, "Speed equals money, how fast do you want to go?"

The OP was asking about rigidity of the ST model compared to earlier models of Haas lathes such as the SL and HL line.

I think if he wanted to know how it compared to a Doosan it wouldn't be in this section. Plus I think it has been established what he wanted to know. Your disdain for HAAS is obvious, so I don't see how this adds anything to the conversation.

The whole Jog both Axis each and every time before indexing Turret issue...Setting 232, shuts that off and life is good.

Guess it helps to read the manual...

Compared to any other lathe you have had experience with, as long as you mention the other lathe and the things that you know of, that set it apart. Any assessment that you care to give is basically fine.

What brand was the other machine?

I looked at a Daewoo and a Hardinge plus toyed with a few other brands. I liked the Daewoo...more coin and another Control to learn. My parts just didn't seem to need more machine just yet.

As to the other machine that went down..Emco Maier.
