Thanks for the input. I think this issue was resolved by the Hass tech, but I will check on those parameters. I will also save those phone numbers.

Thanks Ken for your reply. Its good to know that Haas hasn't turned its back on this issue. We have several Haas machines, and are pretty happy with all of them. We run them hard for 20 hrs a day and...

The Haas tech took a stick of our matieral, and put our program on his thumb drive. He is suppopsed to be sending it to California to have Haas engineers run it on one of their machines.

Sorry, the SL-20 is 11 years old.
They took the rubber out, and told us we were over tightening the live tooling head. The Tech torqued it to 10 Lbft. And it is slightly better, but I think its just...

Just wondering if anybody else has noticed an unusual amount of chatter during live tooling operations with the new ST-20 lathes.
I can use the exact same program, setup, tooling, live tooling...

Please let me know if you have any chatter issues with your live tooling when you get it running. I have a ST-20 that chatters terribly with live tooling. Just wondering if its happening to anyone...

We have a 4 month old Haas ST-20 that will not run a live tooling operation without screaming its butt off and chipping out every flute on the cutter. After 4 days of our favorite Haas tech replacing...

Could be that the machine is locking up on some cutter comp issues.
I have seen the older haas machines do weird things during cutter comp exit moves. I have also seen some completely ignore the...

Thanks for the input. Anybody else?

We are also looking into purchasing this system. Input from users that is not filtered by the seller of the product would mean a bit more to me. Has anybody here used this system??

Anybody?:wave:

These machines that you guys are running wide-slap-open all day long; are any of them 50 Taper spindles?

A sport bike doing 125mph and a F350 diesel doing 125mph are 2 very different things........

This is a joke, Right?:wee:

On a 30 Hp Haas machine, You dont reach 30 HP until the spindle is load is at 200%. The machine will stop if you spend more than 15 consecutive seconds in the red zone, (anything above 150%). A lot...

Im running my third job on our new ST-20, and Im pretty frustrated with the time it takes for the C axis motor to engage. This is the second setup I have done on this machine using live tooling, and...

It's probably been discussed before, but it never hurts to get current info.

Im curious what cutting fluid you guys use.
We have tried several kinds of Valcool, Green Cut, and are now using...

We just got a new ST-20 in about a month ago. Hass has had some rigidity flaws in thier lathes in the past, but they really redesigned the turret, tailstock, and headstock for the ST series lathes. I...

Are you implying that an extended use of the taper offset will cause some kind of problem?
I use it regularly on our SL-30 when I have part deflection or tailstock misalignment issues. Sure it is...

Haastec is right, we dont have all the details, and as far as Haas machines and mold making, they do offer High Speed Mold VMCs that are designed for these long, High RPM jobs. I just dont think...

Ya "DO IT " :D

It is true that Haas does use other methods to cool the spindle, and claim to have improved on this over the years, but I think the bottom line is this, The larger (50taper) mills that seem to have...

There is a Taper offset on the tool geometry screen. It is not on the tool wear screen. The control will not allow large numbers in this column, but usually a change of a couple tenths will do the...

We had a VF5/50 cook a spindle the say way. running wide open for about 7 hrs without the coolant pump running. Haas cools thier spindles with the same coolant you use to cool the tooling. The...

I posted here because I couldnt find a Haas Lathe Forum.

The Gauge on the front of the machine reads hydraulic line pressure applied to the drawtube cylinder. It will go up to 600 psi, but the...

We just installed a new Royal Collett chuck on our ST-20 and it is rated for a max drawtube force of 5,400 lbs. How does this translate to the reading on the Chuck PSI gauge on the front of the...
