@@SteveDelacruz-t6o thank you! Let me know if we can help with anything!

@@goldentrigun thankfully we haven’t had any issues with the aluminum jaws not having enough strength or excessively wearing. Each set of 6 jaws is <$10 in material and 30 minutes of mill spindle time which could be improved on. I have been wanting to make a QG-65 version since they seem to be the most popular size.

@@cobraframebuilding it’s difficult to move from a cnc mill with a real spindle, large tool changer, and big travels to a live tooling lathe. I still find myself making parts on the mill that could/should be made on the lathe because the quantity isn’t there. I understand your dilemma because we mostly do lower quantity jobs as well. What type of live tooling holders are you running?

@@cncmach6779 thanks for the comment. According to Doosan the main spindle has 25 hp and the sub spindle has 10 hp. I have not been able to stall it but I’m not surprised since we’re typically doing light finishing work with the sub. Even with exotic materials, I am curious what type of tool path can stall it and if the setup can be adjusted to allow it to work. A tail stock would have come in handy a few times for longer parts and I am still researching for a way to use a spring loaded live center in the sub. I know Royal sells them but they aren’t cheap.

@@powermoveengineering My puma 2100SY sub spindle is beastly. I think it's rated at 20hp. Main spindle is 30hp. It's amazing. Mostly irrelevant to what I do with it but badass when you can use it.

@@cobraframebuilding that’s awesome. I got a quote for a Puma when buying this Lynx but I was already pushing the limits of what I was willing to spend. I haven’t felt held back by the Lynx quite yet thankfully

We store all scrap metals by material type in 55 gallon drums and have a local recycling company swap the drums about once a month. We do receive money based on the weight but the amount is not very much, only a couple hundred dollars each time depending on the material types.

@@rhemaislife training is always a great idea when it is available. But for this machine we just relied on our past experience working with similar machines. Thankfully we also have colleagues in the same industry that are available for quick consulting.

@@rhemaislife nothing is stopping you! Best of luck!

@@rhemaislife glad you enjoyed. Thank you!

Thank you!

I’ve tried to keep a mindset of “jump in the water now, learn how to swim as quickly as possible”. There’s never a perfect time to do anything so there’s no point in waiting. Bench-top machines are very useful tools but it’s unrealistic to think that they’re competitive in the modern world. I would keep them as supplementary tools for quick and small tasks since they are great to have around a shop. What is preventing you from renting a 1000 square foot space and putting an air compressor and a decent mill in it? I would’ve worked out of a home garage if it was ever an option for me. Set up an S-corp, basic website, and get advice from a CPA. Everyone is so opinionated on taking out loans but I believe they are simply a requirement. Machines are much better investments than something like a car.. Just my two cents! Let me know if you have any questions. Thanks for the comment

Great question. It is my understanding that the process in which stress-proof steel is cold-drawn and thermally treated helps reduce warpage and maintains high strength and wear resistance.

@@powermoveengineering Thank you!

Sure I can share that. Good eye. I try to plug things that trap chips and coolant. Can you send me an email and I’ll reply with it? Thanks for the comment

Bryan@PowerMoveEngineering.com

Much appreciated!

Thank you! More to come soon

We designed those parts to have no features on the backside so that they do not require a second operation. We use a “backside chamfer tool” to break all edges before parting off. However I do think it would be possible to pass these off to the sub spindle if needed. Would just need to make custom soft jaws to match the outer profile. We actually end up surface grinding the back side to make the knife edges sharp and improve the look. I can offer advice if you send me more info about the parts you need to make. Thanks for the comment

I really appreciate you taking the time to reply, thanks. We're looking at making jockey wheels for bicycle derailleurs. If it goes ahead then I'll definitely accept your offer of firing over some more questions! Thanks again. @@powermoveengineering

For me it’s the finishes. Single point turning makes beautiful surfaces with basically no effort. But I do love how versatile mills can be. You can make anything with a mill!

We too

To be honest, it is nothing more than including additional costs into the financing of the machine itself. It just comes down to managing cash and debt. If I can receive $10k in tools from Iscar right now and pay it off over a few years, it gives me the opportunity to have the tools pay for themselves rather than coming up with the money upfront. Hope this helps. Thanks for the comment and kind words.

@@powermoveengineering Thank you for the reply! That sound reasonable.

Bhoom indeed! 😁

That’s definitely more than we’ll be running this machine so hopefully no issues like that for us. Was your problem the machine itself or the Eppinger live tooling holders?

sorry to say RG tools are 5x better than cheaper than eppinger(we had 7 units in 6k total time of work all of them are gone and repair is 2/3 price of new), they dont hold on milling side at all. and the machine drive units give up at 1-2-3k(hr) intervals for active tools@@powermoveengineering

Internal tools have been awesome! I ended up buying those in a used tool auction years ago but I will be looking into more soon. Cheers

Good to hear. The parts warranty ends in 2 months so hopefully it stays this way! No problems so far. Thanks for the comment

I am not familiar with that system but I will look into it. Thanks for the suggestion

Thank you!!

Haha thank you Chad!

I have been debating designing a similar QG65 version for my buddy who has one on his Lynx 2100SY. If enough people show interest, we can definitely make it happen. It is certainly possible to justify the cost of slowly accruing Royal collets for your common production bar stock diameters, but the Op2 oddball sizes and shapes is where it really starts to make sense to have a cheap machinable option. Let us know if we can help with anything and thanks for the comment!

It is a great machine! Seems like the right size for a wide variety of parts and the build quality is there. Let me know if I can help with anything. Thanks for the comment!

That is awesome! Glad to have inspired something. Having easy access to an EDM must be nice. My original idea with making the collet pads was to make them from a single piece of round and then cut them apart using a slitting saw. But setting it up and finding the right tool didn’t seem worth it at the time so we just made them individually on the mill from some 2”x2” bar that we had leftover. Thanks for the comment and let me know how it goes!

My buddy has a QG65 and we have discussed doing the same setup for him. I might get back to you soon on this one! Thanks for the comment!

My buddy got a 2100 one year before I purchased this machine and after seeing how cramped the turret became (especially for sub work), I knew I wanted the next size up. I don’t have any experience with Mazak but from what I understand the quality is top-notch and the mazatrol control can be a game changer for some. I personally don’t like programming at any machine and prefer posting completely finished code from a desktop, so I am happy with this setup. Thanks for the comment and let me know if I can help with anything

😆 Started as a “necessity” making something for myself but hopefully other people like the design and want the same. Thanks for the comment

Thank you! Working on getting more content soon. Hopefully same for you. Subbed 👍🏼

How has it been for you? Any issues with the machine?

​@@powermoveengineering mostly good, we have some annoyances related to chips getting into the coolant tray and coolant splashing next to the door and in the back right corner (which i think is because of the 70 bar (1000 psi) option). the chips in particular means we have to clean it out every day. we only use it for aluminium parts with pretty loose tolerance but we do need to make them fast. we also started with iscar tooling but honestly we weren't so happy with them. we mostly use ceratizit and tungaloy now with ews vx3 live tooling holders, and we're trying out a kennametal u-drill

Thanks for the advice. Seems like there’s a few different ways that could work including the way you’re describing. We ended up just getting another mirrored part-off tool design from Iscar because we wanted to keep a backup on hand and have different options for different parts. Thanks for the comment!

Thank you!

Thank you! Trying to make more soon.

Thank you!

@@powermoveengineering You are welcome

The Y-axis motion shown at 8:34 in this video runs perpendicular to the X-axis. However this machine (and others similar to it) actually put the linear rails and ball screws at a 30deg angle rather than 90deg for rigidity and packaging reasons. The controller compensates for this and does all the math on the back end. So when you move the Y-axis only, it actually uses two different motors and calculates a sine function to put the tools where the g-code says. Hope this helps and let me know if I can help with anything else. Thanks for the comment

@@powermoveengineering So you have the X linear rails and on top of them there is a sort of a saddle with a 30deg slope which also has rails on that slope and on top you have the turret mounted? I assume if you only move Y axis, it will drive both X and Y servos to keep X in position and get a true Y axis only movement with all the sine compensation.

@@car9167 exactly. Sounds like you have the right idea of how they stack up. The X-axis is relatively simple and only uses a single plane. Y-axis requires the X to work in tandem with a 30deg angled axis. I should have included more of that in the video because it is interesting and you can see the movement underneath the turret. I have some technical documents from Doosan that show how it works that I can send to you if you’re interested.

@@powermoveengineering Thanks for your time replying to me. Unfortunately I have lathe controller which can't do that so I will have to think of some way of moving the turret up and down perpendicular to X axis and I have the feeling nobody does that on an actual CNC lathe. I was looking for a configuration somebody or some manufacturer already implemented to get an idea on how to do it. This is a hobby for me and yes I'm trying to build a CNC lathe under $10k

@@car9167 why do you need a Y-axis? The Y-axis is only used during milling so it might be easier to use a 2-axis lathe and a 4-axis mill which could be separate hobby grade machines. It is nice to combine for production but it would be a lot of work to integrate for hobbies unless the journey of inventing something is the main goal

🙌🏽

I believe I have seen those lollipop lines on the Rovi Products website. Thanks for that advice. My buddy has a similar lathe that has a QG65 and we have talked about making a similar setup for him. It’s really hard to justify the cost of the collets unless you know you’re going to make hundreds or thousands of parts using it. Op2 geometry is usually oddball sizes so I think that’s where this system can really help in a bind. Thanks for the comment

Thank you! Hopefully others with collet systems see the advantage and that we can help them out. For now we’ve only worked with QG-65 but the concept can work with other types.

Thank you for the comment. I would be happy to help with integration of this concept into your machine but I am not familiar with that setup. It is definitely nice to not need to rely on outside companies when you are in a bind, especially for something as simple as holding a new bar diameter or OP2 geometry. Plus, nothing is more accurate than machining your work holding in place. It eliminates any tolerance stack up that comes from the machine and chuck. Let me know if I can help with anything, thanks again.

Thank you Anthony! More videos soon.

For the 3" collet we clamped onto a piece of 3" cold rolled steel and then used a carbide drill and 4-40 thread mill. In order to accurately do this we needed to set a C-axis offset that would properly clock the collet. To set this offset we ended up indicating a vise parallel that was in contact with the pins of the Royal fixture shown in the video. It worked well but a degree or two of inaccuracy might be okay in this case. For the jaw segments, we make them in two operations on the mill using a big T-slot cutter so that the second operation is simply facing unused material on the back side. I tried to think of a way to make them more efficiently on the lathe but separating a single piece of round bar into 6 equal segments would be difficult from a tooling perspective. Hope this helps. Thanks for the comment and let me know if we can help with anything else.

Planning on it. Thank you!

I hope those help. Thank you Charles

@powermoveengineering I have ws collet pads that you mount to chuck jaws. Not as repeatable as using that collet.

@@465maltbie the runout has been basically zero because we bore them to size in place. I keep them numbered for consistency when reused but I have not tested if this matters. Initially I had concerns of the material slipping and the lifespan of aluminum, but so far no issues. Let me know if you think we can somehow help you integrate this concept into your setup.
