You Must Balance Your Parts --- Twin Screw Adapter CNC Turning

[@henri1511]

Love these longer videos. It beats TV and totally relaxes me. Great job.

[@zalamachineshop]

Love that people enjoy them. Looking to make them better and more interesting. Will do more in describing the parts and challenges with my face on video.

[@essnoussiyassir1273]

Perfect The boss must be happy if you index the turret with that big sandvik boring bar

[@florian821]

Nice setup, i like it! Without tailstock, this is crazy.

[@emilgabor88]

Always is a pleasure to see some work from this machineshop

[@zalamachineshop]

Love showing my skillz

[@brandonlepsch1143]

Great looking chips!!

[@mannycalavera121]

Love some of your solution's to problems

[@zalamachineshop]

The part is there I just gotta take it out of the material. No problems just obstacles.

[@ChrisMaj]

That piece in this three jaw chuck, you're almost as crazy as I am and I mean it in a good way. If I ever move to New Jersey I'm coming to work for you, but I'm taking my Lathe and VTL with me so you better get a bigger shop by then. 😅😉👍

[@zalamachineshop]

Deal as long as you take videos and post them.

[@davidmiller5832]

I'm here just for the thumbnail. That's Just BEAUTIFUL!

[@zalamachineshop]

I missed a picture of the finished part after polishing. Almost too nice to sell.

[@davidmiller5832]

@@zalamachineshop Well keep making these videos. I don't even need to watch porn after this. And who knows, maybe And maybe I'll stop hearing that "Bow chika Bow Bow" porn music in head everytime I go outside. I might even be able to go on a date, fall in love and discover meaning in my life. See, You gotta make more of this machining porn videos now! If you don't, who knows where my dreary life will lead. 😁

[@bhavarkumavat3202]

Some very deep grooves , how did you do the collision checking ?

[@SoWe1]

17:30 when you're milling that deep in a part wouldn't a different tool and "downward" milling be better? So all the load goes right up into the spindle rather than sideways on the very long tool?

[@zalamachineshop]

Yea but I was looking for my roughing to leave as little as possible for finishing. I don't know how to program plunge milling like that. Not Yet.

[@SoWe1]

@@zalamachineshop :-) when you learned show us hah

[@spazzywhitebelt]

Any guesstimates on time for machining and CAM? You said there were 6 roughing ops for doing the 'groove' (when it's that big is is still a groove haha), did you have to keep sticking the tool holders out more and more?

[@ukaszlubacz2143]

Wszystko robicie w mastercamie?

[@spazzywhitebelt]

There was a injector screw where he was cutting the flutes with an endmill and I believe he programmed that conversationally on the Mori Seiki

[@85CEKR]

I thought he said in one video he used Esprit, could be wrong though.

[@zalamachineshop]

Lukasz Lubacz prawie wszystko na Mastercam, czasami robie na Esprit, programy na Mori Seiki

[@zalamachineshop]

Yea because of the tight space I had to break it down as best as possible. Ended up with the tool sticking out 4.0".

[@theessexhunter1305]

You will need a big piece of fish to go with all those chips.....nice work BTW

[@hansdorfer3371]

Balance is really important on such big Parts! Dont finish one side while the other is unmachined, you wont get a round part.

[@bijaaaczxxx]

Hi , could you say something about quality control , because as I see , parts you make often have dimensions that are either inconvenient or impossible to measure when part is still in a chuck and scrapping such a big piece of material must be expensive . Does your machnie have a probe?

[@gusmcgussy3299]

What????? Wtf u talking about???? Y obviously haven't a clue

[@gusmcgussy3299]

What exactly is impossible to measure???

[@bijaaaczxxx]

@@gusmcgussy3299 mostly about GD&T and organic shapes

[@zalamachineshop]

There are hard to measure features in this part but I will show that in the full video. But mostly I measure everything easy.

[@davidmendoza5186]

That was a big boys roughing b'bar . Are you able to index the turret with it mounted in the machine or did it need to be removed after the operation?

[@zalamachineshop]

No indexing with this big boy. That's why I roughed and finished the inside together.

[@85CEKR]

A bunch of years ago we bought a mori NL2500Y I wish so bad we had gotten an LB4000 we have trouble with the mori constantly and we've got a Captain L470 right next to the mori that runs circle around it and I know the LB4000 is twice the machine as the captain we have.

[@roscosgrow9906]

Why not use a RNMG , seems like a lot of wasted time with the 35 degree. Making large diameter ball valves on a 54 in vertical lathe out of inconel it gets the job done . It's a beautiful finish part anyhow .

[@zalamachineshop]

With tool sticking out fo far I was fighting vibration. I don't use RNMG at all maybe I should. Thanks for the pointer.

[@MarcinKryszak]

Na suchara, bez coolantu? Great video.

[@zalamachineshop]

Dla pokazu.

[@chatnik78]

👍 please more Videos like that with big Parts. How long do you needed for turning?

[@zalamachineshop]

It took about 20 hours for set up, programming and turning.

[@ivanvazquez7465]

Great video! Greetings from OSHA 😂

[@Mr.Saephan503]

😐

[@zalamachineshop]

Who? OSHA Who?

[@HH-Machining]

How much do you decrease feeds/speeds Steel vs 4140/4340?

[@85CEKR]

I would guess he's running between 6-800sfm for roughing and maybe 1000 sfm for finishing. It makes a big difference if it's HT or annealed

[@zalamachineshop]

Yea but its all heat treated. So my sfm is around 420 for roughing and 600 sfm for finishing. I take it slower to make sure my inserts last enough for a few long cuts.

[@85CEKR]

@@zalamachineshop ah, ya I usually run 4140/4340 HT at 450-500 for roughing and 550 for finishing so that makes sense. I love turning big stuff like that in those materials, all you have to do is set your load monitor and then let it run all day long.

[@LifeKnowledgeSeeker]

Awesome as always. Just wondering why did you not use any growing tool for this part. Would it not work duo to the diameter-differences (For example = because of 100% vibration or so) or is it simply faster to use OD tools.

[@zalamachineshop]

I've had issues with large grooving tools vibrating as hell and braking tools in the middle of a job. This is a bit longer but my safer. I can set the tool and walk away for a while if I have to. Grooving might be faster and I do it in many instances but for these I prefer turning.

[@AntonBelovAfrica]

how much is 1 hour of your work?

[@zalamachineshop]

Between 80$-150$ per hour.

[@shiro-r4m]

Awesome!

[@aaronhenderson4359]

I'd love to turn some parts out that are that big, currently the largest parts I make are 3.75 inches in diameter. Small parts are getting old!!!

[@tristinknee5650]

It can be pretty daunting. We don't usually get material with quite as much material to cut off as he did in this video, but some of our parts can be 63" in diameter.

[@zalamachineshop]

Yea Tristin Knee it gets scary and I've scrapped a few too over the years.

[@aaronhenderson4359]

I work as a CNC lathe guy for a small aviation shop in Wisconsin that specializes in electrical components for small aircraft. Work with mainly stainless, aluminum, phenolic, delrin and g10. It's been a great place to get my foot into this trade but I'm ready to move into a more updated shop with larger work with less composite materials. Have 2 interviews this week with a gear shop and a cast iron foundry I used to work for before I got into machining.

[@syraconchita]

why are you beginning with the smallest diameter to cut?

[@zalamachineshop]

I prefer to remove as much weight as possible in the first operation holding with hard jaws. Diameters are close enough where it is very safe. Most jobs I do prefer doing largest diameter first and then the smaller.

[@alexgregg2466]

👌 What G50 did you have set for the facing op?

[@zalamachineshop]

I had it at 600 MAX

[@rollin37]

Is that for a conical twin screw?

[@zalamachineshop]

Yup

[@Wunderbolts]

It’s mind blowing that parts exist where the material removed can be hundreds of pounds

[@zalamachineshop]

Yea and I still see larger parts for quote that we can't handle. I need a bigger Vertical Turret 5 Axis Lathe.

[@Davemcmasters]

Can I come work for you and learn from you? Great programming and i love working on big parts.

If you finish your center work first, then put your your Tail stock in with a plug, it will help ur chatter and save you insert life. Plus it will help with not killing ur hearing lol, keep up the good work bro.
