Large Lathe Trepanning --- Zala Boss Design

[@markneedham8726]

Zala Machine, you could do no better that looking at Dave Wilks videos. Now there is a bloke on top of the game.

[@userwl2850]

Just a heads up guys. The coolant should be run through the tool.. especially on long jobs like this. What can happen is the core gets bigger and the bore gets smaller which can result in the tool getting jammed in the job. The flow of coolant reduces to almost nothing coming out as the core gets tighter in the tool.

[@ryanlynch2259]

I was going to say they should watch your videos.. cheers!

[@zbysiu100]

I see for the fist time in my life such turner work. Nice, very nice.

[@zalamachineshop]

Thanks Zbysiu

[@prabirchakraborty61]

boss you are great. every time I see your work I salutes you.

[@userwl2850]

Looks like I have competition 👏🏻👍 my largest tool cuts 15" and smallest cuts 3.25"

[@ensen89]

I saw this video and thought there is that trepanning guy. I need to search and link the channel. And here you are. :D

[@williamsavory5274]

busted on the copy pasta huh? lol

[@nicovmods]

i saw the vid and directly tought of you :D

[@BomenJager]

@@nicovmods same thirst thought was userwl haha

[@zalamachineshop]

@userwl2850 no way we're competition in the trepanning department. We're just getting our feet wet while you are flying through Inconel. I've watched many of your videos and I'm humbled by your comment.

[@alanprojmec]

Zala boss is the man!!!!

[@jasonnavarro3881]

That's crazy nice video

[@excelengghdr]

Today my boss talk abt trepanning , good work

[@zalamachineshop]

Good luck we prefer to make our own tools.

[@prabirchakraborty61]

it's simply wonder full. I will make one and will try in my lathe .

[@zalamachineshop]

Please share video if you can.

[@marklowe330]

David Wilks video can explain why your coolant feed ishould be through the center of the tool. I still enjoyed the video.

[@brandontscheschlog]

Very cool!

[@weldmachine]

The guy below userwl2850 ( Dave ) has A Lot of experience with Trepanning. It,s mostly all he does. I have to agree with the comment about the Coolant. And Add that if you use More Coolant it will help to flush the chips from the tool also. When you withdrew the tool there was a lot of build up along your tool. Not trying to be negative just involved in your channel. Enjoying your video,s looking forward to more. Thanks for sharing. Peter.

[@zalamachineshop]

Yea he for sure inspired me on the trepanning tools that we're trying. Now on CNC. studio.kzbin.infoom1PsqsC_fc/comments?Fanalytics

Good job

[@kacperAGH]

Gratulacje Panowie, piękny warsztat. Niesamowite maszyny, niesamowita robota. Fachowcy uczyli się fachu w Polsce i wyjechali? Czy już jesteście długo w USA? Jak ma być u nas dobrze jak tacy specjaliści wyjechali:) . Ja działam w CNC od 5 lat, mam 3 Haas -y :), ale przy Waszej robocie to wyglądam jak amator:). Fajnie też że macie kilka polskich maszyn, te nasze tokarki konwencjonalne są chyba na prawdę dobre w porównaniu do innych? Chyba dużo ich w stanach nie ma?:) moja ulubiona to TUE35 , idealnie pod rękę do małych prac. W jakim programie robicie CAMa? ( ja fusion360) Szkoda też że nie ma u nas takich kanałów technicznych do nauki jak te w ameryce ( NYC CNC , Titan CNC , JohnGrinsmo, Edge precision itp) Ja w sumie większości wiedzy zdobyłem na YouTubie. Tyle te ich cale... cieżko się przestawić było? :) dalej myślicie w mm? Czy już w ułamkach?:) Pozdrawiam serdecznie, i oby jak najlepiej :)

[@cncmachinetraining5844]

Very very nice work. Welldone

[@ildarzuf2463]

Hello, very interesting model drill, Especially the solution with the supply of liquid from the outside of the drill through a special channel, tell the channel what is closed ? Sealing rubber ?

[@zalamachineshop]

Actually yes we sealed it with rubber. Works good and we use this tool all the time. In the past we just drilled it now we trepan to save time and get a nice chunk of good material.

[@4alvar]

Takie rzeczy to tylko Polacy mogą wymyślić :D Pozdrawiam :)

Boss zawsze mowi. "Masz leb i chuj, Kombinuj"

[@mynameisjeff5785]

That was cool as f@#$% Great job guys

[@VilsonAlba]

waaaaawww... very very good :)

[@nicholas9900]

How deep? How did you centralise the tool to the steady? How much time saved from boring and drilling?

[@seanb9818]

A trepan tool will go as deep as the depth of the bore of the tool. This particular tool used in the video has a shank which is clamp by the tail stock or saddle (depending on the machine) and is often set within 0.010" thus allowing the steady to be touched on to the diameter of the tool and locked. The tools we use bolt onto our combination turret. With 4 nuts and threaded bar. And because they are old machines we have to use a dti on the work piece to check the tool for concentricity. If we are trepanning inconel or other none magnetic materials we use the chuck to set the tool before loading the work piece.

[@wandylt9977]

very good tool

[@alexd162]

​@@КабановПавел-д7ч Не поверишь! Всё придумано до нас =)

[@egregiss]

Amazing 😮😮😮

[@paulperrin2152]

You should have flood coolant directly through the centre of the trepanning tool, as no dwarf can clog up coolant flow, as it can with the design of the trepanning tool used in the film clip, especially when cutting g tough material

[@zalamachineshop]

Good point. Next time we make one of these we will take that into consideration. Thanks Paul Perrrin.

[@adamsblanchard836]

Looks like that might be how Weatherford made those thingy thingies....oh yeah, not the reamer shoe but the things with one end box threaded and the other pin threads...bout 5' -6' long...idk i only finished about 20,000-50,000 of em

[@Montalva]

that was cool :)

[@zalamachineshop]

Thanks Bud.

[@meepk633]

Why can't you just use a long stick with an insert on it? Like a boring bar the just lets the face run over the insert. Why do you need to catch the slug as you go?

[@zalamachineshop]

This is a proven technique for over a hundred of years now. The slug has to go somewhere and if there is no support it will slump over and possible pinch a single point tool. Plus in order to do this type of cut you need a thin fixturing for the cutting insert and a single boring bar just wouldn't cut it. Literally.

[@Davemcmasters]

What's the purpose of doing that instead of buying pipe that size?

[@ensen89]

Sometimes you just don't find a pipe with the right od, id and alloy. Happenend to me several times.

[@zalamachineshop]

A lot of material types are only available in solid bar. Tube can be found but sometimes much bigger.

[@tomituononen7192]

Pipe is more expensive per kg.

[@Zucsebe]

Is this Germany based ??

[@zalamachineshop]

No my friend we're USA based.

see it because have a task drill a hole D90mm to make pipe 3620мм.... drilling will do thru spindle hole, it is 105mm...... on a bulgarian s-13 lathe a have. Very interesting. thanks

[@sebastianschwobel5688]

check out userwl2850 on youtube, he does a lot of trepanning with tools he builds himself. reminded me a lot of the tool ur father dsigned.

[@zalamachineshop]

Yea that guy is tops in trepanning. His Inconel trepanning is very very impressive.

[@userwl2850]

I made a video for you. I will show it tomorrow. If you leave me a comment I can pin it.

[@gildermelo862]

And you have a new raw material extracted....

[@zalamachineshop]

Yes this counts as an extra win. Instead of sending the material with the chips like we used to now we have high quality material left over.

[@Bugnarok]

Win win solution, great job

[@nikolaiownz]

@@zalamachineshop yeah scrap prices are shit so I see why you do this on expensive materials
