[@franklinperformance]

Great job on the spindle design and idea to machine these parts. I own two Integrexes and although we never get jobs as wild as what you do, being able to mill and turn the hydraulic components we make in one setup is such a game changer. If you make a V2 of this offset spindle it wouldn’t be too difficult to make it through coolant using the area between your angular contact bearings and end support bearing - even with external piping from the flood coolant outlets up top

Hi Peter. Thanks so much for the video showing the use of this tool. I appreciate the full explanation. I just hope it all works out and I am sure it will. I would love to see how you will test the device before machining the part. I have a feeling you may need to alter the size slightly to allow clearance. (former CNC machinist and current mechanical designer engineer) As always I am amazed by your ideas.

[@EdgePrecision]

I have some aluminum setup material with a short part of the slot the same as the part. To set up on. I think the clearance should be fine. There isn’t any material to machine away anyway. So it will have to do.

[@rowycoracing]

Very nice design to accomplish a difficult task.

[@d6c10k4]

Impressive work as usual. Gotta love how and engineer can design stuff that's near to impossible to machine. The only other method Ii can think of would be to use ram EDM to reach those bores from the side.

[@EdgePrecision]

We did discuss Ram EDM. But the parts are over feet long. There is a shop here in Houston that could do this. But every time you send a part out of your shop to another you loose control of it and there is the possibility of scrapping the part by the other shop. Not to mention having to pay for that service and the time it takes. Now we are only doing two assemblies (This is just one piece of a larger assembly that gets electron beam welded together). But there are more in the future to do. so it seemed good to devise a way to doo it ourselves.

[@steveshopworxmachine5716]

If the coolant drain becomes a problem you could hook up a shop vac to the underside to the through holes to help expedite the draining.

[@EdgePrecision]

What I thought if it becomes a problem. To purge air inside the spindle to keep the coolant out. This is the way it is done on commercial CNC equipment.

[@bigbird2100]

Great video 👍pity a small brush less motor couldn't be found to do this but then we wouldn't learn lor share it great video 👍

[@ikocheratcr]

Could it be possible to add an air in port to the "new spindle" housing, so you can have a little of positive air pressure inside it while operating and avoid cooling getting in?

[@ohsnapfit2096]

You honor the Houston Texas machining industry

[@petedeal8678]

Thanks for the appreciation information. With so little clearance the cutter radius is going to be very close to the bore radius. Might this be an issue with quite a bit of cutter engagement? Tendency to chatter?

[@bobvines00]

I'm 10 days late, but is there too little space to add a "coolant-proof" seal to protect your spindle bearings? Thank you for sharing the model so that we can better understand the reasoning behind everything. I wonder whether the designer of the part you're planning to machine actually *needs* those 30° chamfers on the groove or if the groove design could be changed to something less expensive to machine? Edit: I was a Mechanical Engineering designer when I was young and the Tool Makers that built nearly everything that I designed all knew that I was *always* open to changes to my designs that didn't adversely affect the purpose(s) of the design.

[@dumpsterdave3710]

Can anyone offer insight into why this part would need such absurd features designed into it? It almost feels like the designing engineer didn't think for a second how it was going to be manufactured. Is it likely to be like that, or is it more likely to be some critical feature that must be designed in this mind-boggling way?

[@mgraen]

Most likely a critical feature. However, sometimes you're boxed in by decisions made earlier in the design process. Another very common one is your project time is chopped off by management while you're trying to improve the manufacturability.

[@lawmate]

Amazing work! Is that like an iscar ITS connection? Did you consider buying a spindle from nakanishi or other manufacturer? Or use a lathe live tool spindle with a capto connection?

[@EdgePrecision]

No I did not consider purchasing a spindle. I needed the ITS MB50 connection for the boring heads I plan to use. Otherwise I would need adapters to use these boring heads. This just increases the tool length with those obvious disadvantages. So commercially available spindles just would not do what I needed.

@@precisioncomponentllc1820 There is a shop here in town that can do it (probably). But this is a very expensive part to a larger assembly. It is always better if you can do this kind of stuff in your own shop. You tend to lose control of quality and of coerce there is the time and cost as well. There are more of these part coming in the future so it would be better to do it all here. So the decision was to go with this idea. Mostly for the future parts as well.

[@bigbattenberg]

Building a spindle is something I would not even dare to touch. There is so much involved that it is truly mind boggling. I am very interested in how this is going to turn out. Especially stability is a very likely problem area. What material is the part?

These parts are titanium.

[@GlassImpressions]

I’m curious why you don’t chamfer in the mill. At least on one side.

That green loctite is something. We made a tool for NOV several years ago that called for it to attach a slip on drive key into a shaft.

[@bigbattenberg]

Love the stuff. Many of my designs use it as default. Love the fact that it assembles by hand without stressing the materials and the tolerances can be just a bit less tight which saves time and money. When dead on accuracy is required post-machining can be done as I sometimes do on repair jobs, leaving a bit of stock beforehand.

[@daibauga]

Brilliant work. Regarding your Mazak, not that I'll ever use one, but what is the operating life and servicing requirements? Also what make is your burr grinder?

The hand grinder is a NSK Espert 500. This machine was built in 2006 and is still going strong. Servicing requirements I don't know what you are asking with that? In all those years I have only replaced one Hydraulic pump and one power supply.

[@exol511]

I am unsure, but fixed KM lock nut spanners like this are fairly standard at the local machine repair shop as well as in EU (I bought some locally, to tighten precision ballscrew nuts), so it might be that the engineer was looking at EU specs for the spindle nut?

[@wolpumba4099]

*Summary* * *(**0:00**)* *Special Wrench Creation:* The creator made a special, thin wrench (3/16" thick) out of Starrett flat stock. This was necessary because no commercially available wrench could fit in the tight space required for a specific spindle assembly. He might heat treat the wrench for durability. * *(**2:25**)* *Spindle Assembly Purpose:* The spindle is part of a larger assembly being built for a client. This assembly is designed to machine complex features inside a part, specifically hard-to-reach bores with grooves and chamfers. * *(**9:14**)* *Unusual Part Design:* The client's part has an unusual design with awkward features, including off-center bores and undercut grooves. This design makes machining difficult and necessitates the specialized tooling being created in the video series. * *(**11:14**)* *Solution Explained:* To machine the part effectively, the creator is constructing a custom spindle assembly that mounts on a Mazak lathe. This assembly uses a 90-degree attachment and will allow for tool changes with an Allen wrench. * *(**14:14**)* *Coolant Considerations:* The design of the part and its tight tolerances require careful consideration of coolant usage. The creator mentions the need to limit coolant flow to prevent it from pooling in the part and potentially damaging the spindle bearings. * *(**16:08**)* *Video Series:* This video is part of a larger series documenting the build of the custom spindle assembly. The next video will likely cover boring out the housing for the spindle cartridge. * *(**11:14**)* *Why Not Traditional Methods?:* The client had previously machined this part using a vertical mill with angle heads, which was inefficient for tool changes and repeatability. The custom solution offers a more efficient and precise method. I used Google Gemini 1.5 Pro exp 0801 to summarize the transcript. Cost (if I didn't use the free tier): $0.0521 Time: 20.50 seconds Input tokens: 12715 Output tokens: 721

That spindle looks like one of ED-209's cannons.

[@processagent5095]

I see holes on the face of the sheave. Was the taper lock bored out of it to fit your application? Or are those holes for locking it on the shaft? I'm not saying lock-tite won't work, but it seems a couple of set screws and a keyway might be applicable. What would be really cool is if you made your own sheave. You could split in two along the groove around the circumference and have a taper on each side where they come together. Run some bolts thru the face and they'll lock together and easily clock however might be needed. Maybe a belt tensioner, if your worried about clocking accuracy. Cool project. Seems like you could make a nice chunk of change selling these heads to Integrex owners. Nice to see you back making videos on a regular basis.

[@EdgePrecision]

Yes I bored out the taper lock on the sheaves. The head has a way to tension the belt. I’m going to try the locktite by itself. But I do have a plan to put pins if necessary.

Other than just building a really cool attachment! I have no criticism, just huge curiosity. What is the mission statement? It’s 1:1 so same spindle speed, it’s less rigid than the main spindle, it’s complex, the belt is a wear item, the main spindle can travel below the lathe spindle. So why the offset? The only explanation I can think of is that it requires much less clearance under it and on the front and back. But that is easily cured with an extended reach holder.

[@EdgePrecision]

I showed in this video the reason? I have to do machine work on the end faces in this part's long slot/cutout. In order to get the tooling in there, I need this smaller spindle. The 1:1 Ratio just makes it easer to program and that's all the room I had for the belt drive anyway. The Mazaks milling spindle can rotate from 0-10,000 RPM with 50 Hp. So there will be no trouble with speed or power at that ratio. In this case I drought that I will need more than 3000 RPM anyway. Also I don't need in this case to tap anything but a 1:1 ratio make rigid tapping work better too. If I ever needed to do that in the future with this attachment.

When doing milling work in a vise like this, how do you go about setting your xyz for the programming? I'm in the process of making a fixture/vise setup for my MK4 Integrex to do some more convetional milling work, but I'm struggling a bit with figuring out how to zero the part once it's in the vise

[@EdgePrecision]

Are you intending to program with Mazatrol or Cam software? I always use a Cam program. So you would set your fixture offset (Say G54) to the zero point on your part in the X,Y,Z with your probe or indicators edge finder what ever. This is a little confusing because your fixture offset zero is in relation to the machine's coordinate system. In other words not rotated. So the X will be the Z axis and the Z will be the X axis when rotated. But don't worry about that at the machine. The Cam software should take care of the rotation. Maybe the Mazatrol will also but I have never done this in Mazatrol. In your cam software you need your part positioned in the same orientation as the actual setup on the machine. This way you cam software will output code properly. Here is the beginning cod of the wrench program in this video.

Used to countersink holes in CFRP assemblies. I did not stay around long enough to learn if it was a success. Crazy business.

But we earned so much at that point so that was not an issue and I saw money in the millions just go through every week. And that was pretty much just so we could hit the tolerances that was insane and for long pieces as well. On one, of many times, when we made what looked like a very expensive and complex and hard to make item, I asked what it would cost. At the moment they didn't knew since it would take several weeks to make it but surely in the millions they said. NASA didn't care, they just wanted it period, cost didn't matter.
