I think it is nice for the right application.
Here is the same questiom though:
What are YOUR thoughts on this kind of small lathe?
http://news.thomasnet.com/images/large/011/11539.jpg
I mean if there is a market ( even if a perceived one ) for 4 different versions of a toolroom lathe, what does the "Corporate Wishdom" say about one of those?
Mine has not seen many days off in 3 years.
Is it possible that between multiple versions of routers, toolroom mills, toolroom lathes, office mills, office lathes, slant bed lathes, VMC-s, HMC-s, pallet changers, barfeeders, rotary tables, indexers.... Is it possible... Is it concievable that there is just not enough room for a solid Gang tool lathe?
Specially when 90% of the hardware, 100% of the electronics and 100% of the software is in existence?
Possible that Omniturn can survive with nothing but? SNK ditto? Can Haas not absorb the re-initiation costs?
Just what is the reason behind retiring that machine and never to be mentioned again?
Seriously. Can't tell you much on the HPCL, but can write an essay on the MiniLathe.
Sorry.
I thought it was discussed quite a bit in other threads here. This is my impression (which might be totally wrong--but this is how I view it after many hours spent in the Haas booth at Westec, online and drooling on brochures):
The TL-1 could be equipped the same for $8K less, give every bit of performance and always have the option of larger parts. It's limited to 2K but I'd bet that 3K is a parameter change away (especially with a collet closer).
I just don't see the market in the HPCL--except that it returns the punch by Hardinge for copying the Haas rotary products so blatantly.
Did I miss anything? Really? I love to learn. If I missed some incredible capability that it has, please enlighten me. I like Haas products but I can't see it's purpose in life. I'd rather see a Haas-controlled EDM (man, that'll open up a can of worms ).

Well Geof.... Here is my take on it.
First off, I am a Haas guy. Have 4 machines and a rotary, will be looking at more later, specially that new ST30.
If the HPCL was a poke at Hardinge, then I think it missed the mark. It does not appear nearly as robust as a Hardinge chucker, which is what makes them so incredibly indispensible. Without the accompanying 8-station turret on a Hardinge, it is even less versatile.
Don't know how much the skinny ways effect accuracy against the Hardinge chucker, but mine is a 1966 vintage and .0005 overall repeatedly is a non issue.
Doubt the HPCL could do that in manual. Maybe, but doubt it.
The Hardinge style is also used for their gang machines. Stout ways, slides, spindle assy little bigger but robust. Great great CNC gang machine, albeit small on X travel.
Somehow I don't see the HPCL in it's current, slightly wimpy incarnation as a competition for that.
In manual mode it is a little tight to handle, just like the TL-s. The slide has a limited travel, so it can mostly be used for second-op only, and even then only a limited # of tools.
Use it as a precision toolroom lathe? Don't know as I have never actually tried it. Perhaps that would be it's saving grace.
My chucker gets the fussiest stuff put on it, albeit only in manual mode. I also use it for all kinds of little stuff that comes up in a jobshop anywhere from cleaning a rough piece of stock to making a multiple step fixture pin to +/-.0002 tolerances, turning the head on a bolt, manually tapping something really crappy crap, repairing screwups or just doing precision cutoffs.
For that though the Hardinge is just the ticket.
It's just my opinion but I'm dumb as a stump.
I'm a pretty happy TL-1 owner. I've had mine since November. It's my first CNC lathe but it replaced a pretty nice Cadillac (Yang) 16x40 manual lathe. I worried that I couldn't do the 'quick cleanup' type jobs on it but I've gotten pretty good with setting it up and running it.
Last night, I chucked and recut the spheres on some brass ball/lugs that came out slightly out of round (Tool Nose Compensation issues). I located them, ran them and tuned those ball surfaces to get them into spec.
When I was done, I turned some beams against a center. They were made in the mill with round stubs on each end. They needed to be trued and shaved a bit for assembly clearance. No programming: just turning handles and starting/stopping the spindle--a manual lathe job.
It's not perfect but I sure like what it does--especially for the money. The operations I've just described are what I see the HPCL being intended for. I still don't see its advantage over the TL-1.
I shut down the TL, pretty darned satisfied at what I've done with it in 4 months. This morning, I tried to fire it up, only to have the 325V DC power supply pop a capacitor inside the cabinet. Good thing it's still under warranty.

"The TL-1 could be equipped the same for $8K less, give every bit of performance and always have the option of larger parts."
Good point. I guess they price it higher because of space saver.
I wonder if it was priced @ $19,999.00 if it would generate the demand for them.
I think they're a great entry cnc machine.
The tolerance on them are pretty good too.
Tailstock taper cut is < .0005 over 10"
Spindle taper cut is < .0002 over 4"
I don't believe any of those claims anymore. I don't want to rain on the Haas parade or sound like I'm whining but my brand-new TL-1 couldn't match its claimed inspection sheet after a 99 mile trip to my house.

I read your blog about your problem ... and it had me baffled ... I know they test cut every machine before it leaves. They do a tailstock taper cut over 10" ... they must of got a good taper or they wouldn't send it to the customer like that .. or at least I hope they wouldn't. That problem still bugs me. I'm wondering if the linear guide lifted, is loose or something happened during transit .. did you notice anything odd with the packaging when the machine arrived. Haas packs them pretty nicely .. you might of noticed if something did happen
I don't want to hijack this thread but to answer your question:
The machine was spotless and wrapped tight when it arrived. However, it did have a bunch of hours (more than a hundred...I can't remember exactly) and about 1,000 M30 counts. So it had been doing some kind of testing or whatever back at the factory. I wonder if it hadn't been properly leveled while that went on and if it might have been resting on three legs as the casting aged.
I've had it parked on three legs for a couple of months now. I'm still trying to un-twist it. We'll see.
I should also post this in its own thread because I mentioned it elsewhere as a problem on this TL-1. It's not really worthy of a thread so I'll post it here in hope of righting the bad information:
I had considerable power problems with the machine when it was delivered. It popped my sub-panel and main panel breakers on every control start-up. I had to run outside, reset the breaker, then run back in to get it to start before the capacitors leaked back down. I posted this as being a potential problem buying single-phase machine (TL, TM, OM, etc).
Being intermittent, it was a tough problem to diagnose. It was mentioned at installation but it was suggested that I had a power problem, not a machine problem.
Yesterday morning, the problem ended with a small explosion from inside the control cabinet. The Torrance HFO had a tech inside that cabinet 5 hours after I called them. The 325V DC power supply (does the job of the Vector Drive in the low-HP machines) had cooked itself.
They express shippped a brand new one from the factory. Another tech was there this afternoon and installed it. He checked everything else to make sure that was the problem. Absolutely no more problems with blowing breakers. She started up and shut down three times in an hour without a wimper from the circuit breakers.
While he was checking things out, I peered through the cooling grate on the blown one. A circuit trace right next to the incoming power connection had exploded off the board. It ran from the connector to the high-current rectifier block.
It looks like the rectifier was partially shorted from the factory and took this long to finally cause some identifiable damage. From the look of the board, it had been cooking for quite awhile before the catastrophic failure. I understand that electronic problems are hard to track down--especially like this one. It's just a matter of all of the thousands of components going in: some of them are bound to have problems once in awhile.
So to set the record straight: a 40 Amp Haas machine will run just fine on a 50A, single-phase circuit. If it doesn't, there is a problem with the power supply inside the machine. There. I posted it. Neither I, nor anybody will ever need that information because it will never again happen on this earth.
I'm really, really glad that this happened under warranty. Still, everybody was 'Johnny on the spot' with fixing a lowly TL-1. Thank you to the Torrance HFO for a job well done.

To me this is the perfect size lathe having used a TL-2 which can't even chuck on a bar smaller than 3/4" OD, but I agree on the cost argument that no one is going to buy this machine when you can get a TL-1 for 10K less.
However, for the certain customer like me who wants the functionality of the TL-1 without the size and I love 5C, only use a 3 jaw once in awhile. I like to have my face right down there on those little parts and I don't want a chuck sloggin my noggin. Plus one major feature which you guys missed is the standard C-axis on the HPCL not even offered as an option on TL.
It's the perfect lathe for a prototype shop, but the price is just too high.
I belive the Hardinge dig might be somewhat true but remember the base price on a new HLV is $50K for a MANUAL lathe. Of course they claim .00005 (fifty millionths) but I don't need that.
I think most people would opt to go up slightly to a GT10 or SL10, or down slightly to a TL1
It sounds like they may be discontinuing this lathe.
That seems to be a problem with the tooling selection, not the machine. There are plenty of collet noses for the TL-2's A2-6 spindle, including 5C.
I have a Royal 5C lever closer in my TL-1 right now. It's long enough to get away from the headstock and it flings a lot less coolant than the jaws on a chuck. The only bummer is that the one I selected is not 'dead length.'
Greg
I know nothing about that machine, but from the picture alone I like the handles but it looks like moving the tail stock will be a pain in the ass.

I would like to get a CNC lathe sometime in the next year so I'm very early in the selection process. My total CNC experience is 18 months with a Haas TM-1P so most everything about CNC is new to me. I'm interested in this thread because I'm looking for a small machine and want to have the capability to make runs of a couple hundred of whatever and it looks like the GT series would work best for those size runs.
When I option up the TL-1 with a full enclosure, remote tool post, 3500 rpm, flood coolant, and some type of after market automated chucking system it's just as costly as the GT series. This says nothing for the 8 tool turret advantage the GT has over the TL-1 tool post.
So am I correct in assuming that the main advantage of the TL-1 is it's ability to cut for 30" rather then 8 or 12, and the utility of the hand wheels? Keeping in mind that I've never turned a CNC lathe on, I've found the Haas mill is quite easy to "drive around" with the jogging features and have not missed my Bridgeport clone at all. Would I be able to run the GT or SL series of lathes in a similar manner?
Vern
The GT or SL machines are just as simple to jog around as the mills so if you are comfortable using the jog wheel and keys to move your axes you will be fine. The lathes do have a difference in that there is no Jog Lock, the center key gives you rapid motion which is handy sometimes but dangerous.
If the size of your parts will fit within the GT20 capacity that could be the best machine. Take note however that it is difficult to go much above 6" of work length because the chuck takes up some space and tool holders take some space; boring is particularly limited.
You can get a hydraulic chuck on the GT20 and this is very handy if you are going to rig a barfeed or pull the bars. The maximum bar size in this case is just over 2"; do not believe the Haas website 2-1/16" will not fit.
If you stick with manual chucks you can do up to 2-1/4" with an 8" Bison and it is possible to adapt a 10" chuck and do up to 2-3/4".
If you get carried away like we have it is possible to retrofit a hydraulic chuck and cylinder assembly that will take 2-3/4".
It is also feasible to do 100 unit production work on the TL1-P with the new servo toolchanger; it is not as painfully slow as it used to be. The slow rapids do slow things down and only having four positions on the toolpost is limiting although it is possible to get around it by ganging two or more tools at one position.
If most of the work will be 100 or more units production with only occasional one-off prototyping the GT20 is almost certainly the best choice. However, if most of the use of the machine will be prototyping with production occurring only occasionally the TL may be better.
The GT and SL machines are not as convenient to switch tools in and out of when doing prototyping and one-offs. Also it is not as easy to check a program out and make sure all the clearances are okay
An open mind is a virtue...so long as all the common sense has not leaked out.
Nice to see the A team working on Saturday. I didn't realize the chuck and tools had to be included in the available Z travel. Six inches is not lot to work with, in the case of the GT10 I guess that drops to 3 or 4 inches.
This is why I love these forums, they narrow the dumb error band considerably.
I'm not opposed to used equipment so maybe I should look for a used SL and find the space to accommodate the extra size. I was trying to stay away from gang tooling but it is always another alternative.
I looked for a picture of the servo tool post on the Haas site but no luck. I'm curious as to how you would get two tools on one or more of the four positions? Boy, there is a big big difference in the rapids!
Vern
Lookit pretty pictures I posted in these threads:

Yes there is a bbbbiiiiigggg difference in the rapids; the GT and SL machines are approaching scary.

Thanks Geof, that is some innovative tool holding. Does the 4 position tool post index as accurately as the turret on the GT-20?
I can see where a 3 jaw would eat up some of the precious Z travel on the GT's, if you use collets do you get most of it back?
Vern
First question; yes I think so. Or I should say I have turned similar parts on both machines and the variation between sequential parts has been undetectable with a micrometer so the turret(s) must be indexing reliably.
Second question; yes, the collet holder will probably be shorter than the jaws on a chuck.
An open mind is a virtue...so long as all the common sense has not leaked out.
Geof,
In that first post you listed, what makes the tool holder rotate 90 degrees? The operator?
