Spindle Sync is a powerful tool. Remember to align the Main and Secondary Spindles, using a custom R (sync angle) value with your G199 if the orientation of the Main and Sub need to match, this is shown at 03:21. Always test run your G199, without a part, and with lots of space between those chucks, as you proof out your program for the first time. - Mark

This keeps getting better. Other manufacturers need to pay attention.

[@JacentySki]

Mark, You are the best. I'm waiting for this video.

Интересное кино.

[@turborulz72]

Wow, excellent video.

[@GRTLRS]

Perfect timing. Tech is here right now installing our DS30Y. Can't wait

[@markterryberry4477]

It really is cool to watch. Have fun!

[@mrsaiyan3237]

Very much wow!

Спасибо Вам за видео.👍👍👍

[@colehawkins6623]

Great video Mark as always. Is there an option to run a live center on a sub spindle machine?

[@homer4889]

Hi, Can you please help me on this one. I have the same setup but running with bar feeding. And this is what I want to do, instead of pushing the bar i want it to be pulled by the sub-spindle, part it off while sub is still holding it, automatically update the length of the bar, then continue on and repeat the process. But i can't somehow update the length if it is not to be feeder pushed.

[@G0Z100]

you make it look easy

[@markterryberry4477]

This one looks really cool, and complicated, but the designers really did a good job of making this process super simple. Every design conversation, here at Haas, starts and ends with "Sure, that works, but how do we simplify the process".

[@derekfriedrichs]

We were thinking about a ST20Y with a dual spindle, but DS30Y looks like a better option. Bigger machine for sure, but a much better secondary spindle that is dedicated.

[@scottwatrous]

Just getting into learning the ST-10 and partly glad I started on a basic lathe not one with the dual-spindles and live tooling as there's a lot to figure out! That said very much looking forward to a DS lathe in the future, it'll only be a short amount of time before I've got the basic 2-axis stuff down. Looking forward to more lathe videos, they're going to be needed!

[@TheFeralEngineer]

I always say buy all of the capacity you'll ever need and learn it in chunks. Just because you don't know how to use live tooling, Y axis and sub spindle doesn't mean you won't need it and can't learn it after you've got a hang on the basics. Once you can touch off turning tools and set up a job on the main spindle, the sub work is more of the same. Live tooling has nuances of its own, but even that isn't the end of the world to figure out with time

[@scottwatrous]

That's a good point and one I also considered. But the difference in price meant we cpild upgrade from a Mini Mill to a VF2 to make up for it, and I dare say that it's a better setup for starting out.

[@robdejong133]

Would this system be suitable to turn a long shaft complete? Example: -1st spindle for turning 1st face of shaft and some of the outside diameter of shaft. -synchronize 1st & 2nd spindle while holding both ends of shaft and turn middle outside diameter. -2nd spindle for turning 2nd face of shaft and some of the outside diameter of shaft.

[@Qui_Gon_Ben]

i'd love to see a Haas Tip of The Day video covering all aspects of the Baxis. How to jog it, touch it off, programming a job for it etc..

[@markterryberry4477]

That is a great topic. We'll move it up on the list. In general, its best to touch-off all sub-facing tools manually. And to program on the sub, we will write our programs as if we were running on the Main Spindle (left facing) and then use a G14 Spindle Swap command to mirror all commands for the sub. Everything is swapped with a G14, even our M03 spindle command will make the sub spin when in G14 Spindle Swap. Great comment.

[@jayt701]

[@SuperAWaC]

When using a soft jaw in the subspindle where you want the part to register on a shoulder against the back of the soft jaw, how do you securely seat the part during the handoff without having to crash the spindle into the part to do it? Do you have to use a tool with a pusher spring or something to re-seat the part after the swap?

[@markterryberry4477]

The handoffs can be controlled really well, so accurately that we don't usually need the parts re-seated with a die spring, like we see here: kzbin.info/www/bejne/o33Cp2qZip2fZ5I

[@DarkStormIndustries]

Trying to use our sub-spindle to support a part while we do some milling. G199 does not seem to be compatible with M154 C Axis. Just want the subspindle to clamp and rotate freely when I move C axis to position for milling. No matter what I try get an alarm (varying). Very frustrating as this seems like a simple concept and well within the mechanical capabilities of the machine.

[@phranklyn]

Can you show techniques to line up the two chucks accurately, that isn't just eyeballing it?

[@markterryberry4477]

We can orient the spindles, and then run an indicator (magbase on turret) across the jaws, or a feature on the part, as we rotate the C-axis until we find that perfect position, that can be used as our G199 +/- R angle. Every setup is unique, so we will have to get creative.

[@steelfalcon2755]

Can the sub spindle be used as a tailstock with the 60 degree live center? Will it hold enough pressure against the part?

[@markterryberry4477]

We will see customers making use of spring-loaded live centers, held in their subspindle chucks (Royal, Slater, Concentric, Riten all make them. The Rohm MT4 is what we have used, nice). The MT4 adapter that can be held in the chuck is what you would need, along with the spring-live-center. That would make a great option, we'll look into again.

[@sinq6807]

No.

[@jacknickolstine3355]

I wanna learn more hahahahah

[@ronaldearly9963]

How do I manually jog the b axis? You didn’t mention that. It may sound dumb, but I can move it in mdi or the program, but don’t know how to manually move it

[@AgMasterplan]

Press "B" and "Handle Jog"

[@Tnj8228]

I wish this was more clear ha still xant figure it out

[@Noo_Namee_cnc]

Why there are no safe limits in Nm

[@markterryberry4477]

Take a look at our Safe Run Mode. It can prevent damage to the machine, while in G00 rapid moves. www.haascnc.com/productivity/control/safe-run.html Beyond this, we do have limits set on all axes, and we will give alarms if we go above these limits. For the spindles, this becomes more difficult, as they have such high horsepower/watts. Running all of these programs with extra clearances, and at 5% rapid, until we are comfortable, is the best approach. Once the program has been proofed, it will repeat safely of course.

[@lvxleather]

There is a mistake in the thumbnail graphic and in the video, the G-code towards the end, it says 'G97 ( RETURN TO FEED PER REV)', it should be a G99.

[@markterryberry4477]

Thanks Lvx. It turns out that my mistake there was in the comment, not the code. It should read G97 (Turn off Constant Surface Speed, S equals RPM).

[@user-zg5vd2gl6n]

Hello, why is code G 98 here?????​@@markterryberry4477

[@BGraves]

Stock Air nozzle got removed day 1 because it seems like every operation it wanted to hit the turret or a tool on it. Replace it with an adjustable one, please. High pressure coolant does the trick in the meantime.

[@markterryberry4477]

I will usually cut the tube down, and bend the tip out a little bit, when running on a 3-jaw chuck. The length out-of-the-box is pretty good for most Collet chucks. Great input.

[@BGraves]

@@markterryberry4477 same goes for the bar feeder liners I suppose. Going to have to 3d print a spindle liner extension that pops into the bore of the 3 jaw chuck and sits behind the jaws so i dont have to set the bar feeder to stop feeding at 10" remaining. This remnant is then too big to be pushed into the parts catcher, so bars have to be loaded one at a time. Yes, "get a collet chuck"... I agree

[@BGraves]

@@markterryberry4477 I also plan to take the bar feeder cover plate and cut a three and a half inch hole in it with a see-through window for bar feeder height alignment and then line the cut out with flexible strip brush so when the coolant makes its way up the spindle liner housing it doesn't spin and splash outside of the spindle housing enclosure and all over the floor. I'll let you know how it goes?

[@BGraves]

@@markterryberry4477 oh and when the chip tray screen gets covered in small chips the coolant when draining doesn't penetrate through the screen and splash into the reservoir it hits the chip and splashes all over the front sheet metal of the machine and drains all over the floor. Such an easy fix to add a splash guard that drains back into the chip tray.

[@BGraves]

@@markterryberry4477 oh and when the high pressure coolant is lined up just right it shoots through the gap in the door and splashes all over the floor. Also, hydrophobic tablet screen protector applied to the inside of the glass means you can actually watch the parts being machined. Not sure of the economics of that but it would be wonderful if you guys could offer that is an upgrade for the whole window

[@trolltv1282]

How to transfer hexagonal bar?

[@Shockdagon]

use the g199 r option. He explained this in the video. But it allows you to set the angle of offset on the spindle sync up. it was how he actually meshed the two chucks together.

[@TheFeralEngineer]

On a Mori, you just clamp the material on both chucks, go to the phase adjustment page, select mdi and press execute. Beats all of the guesswork. For accurate sub transfers, you speed sync to position for sake of air blow, then enable and home each C axis motor. Super accurate. I do like the angle adjustment feature of the G199 thing, though.

[@ExMachinaEngineering]

OK... At 06:46... That is an actual part isn't it..? Show how you did that!!!

[@markterryberry4477]

That looks pretty good, huh. Ric, our editor on this one, did some magic on that scene to reinforce the message. It does look pretty real though.

[@scottwatrous]

That looks like some Adobe Magik to me, but still drives the point home.

[@ExMachinaEngineering]

@@markterryberry4477 If it's photoshopped then it's pretty good work. With your track record I thought you were working on a new canned cycle to sync the X-axis to turn eccentric in real time.

[@TheFeralEngineer]

Meh, I set B in a work offset and program all positive numbers from my grip point, but that's on a Mori. I've never used one of these tinker toys.

[@markterryberry4477]

That’s a great method. We can set our B axis in our Work Offset, I just don’t like teaching that right out of the gate. I’m worried someone might make a work offset change to adjust the Z on their subspindle part, and accidentally crash something during the handoff. Leaving the handoff position as a G53 move forces you to be very deliberate when making changes to it. An operator may change a G55 offset, but they won’t typically change a B-axis value in the program.

[@tru.genetics6023]

If you were to make a simplified (affordable) and much smaller bench top lathe for glass work. (flame working.). I’d buy 10. You’d sell over 250k units the first year… The flame working industry doesn’t have a affordable lathe…. lol ok

[@tru.genetics6023]

Seriously thought. All it would need it is synchronized chuck speeds and zero to around 400 RPMs with a bore of 85 mm in a bed length of about 3 feet(ish). And hollow spindle for a blow hose. Super simple and honestly an entry-level Smalleys that could sell for under 3500 would sell millions of units
