WOTAN RAPID - 1 CNC PELTON RUNNER MILLING

[@aahl1680]

It is nice to see these old Ladies still working. I have been working at WOTAN and building these Beauties in the 80ies. Nice Video, Thanks!!

[@wroarrrrrr]

+aahl1680 Wotan rapid 1 is still the most precise and stabile maschine,it have been made in tolerance 0.5 Schlessinger meine is still in 0.01 mm.The other new maschines are made in 6 months but i NEWER change wotan for new.I hawe 65 Kw and 4900Nm torque it is great maschine i dont know why did not produced anymoore.Sorry for bad english.

[@thelamb288]

I just found out that the original Pelton wheel was invented by Lester Allan Pelton in the 1870s. Mind blowing. Cheers.

[@Bouregard3]

Is there a reason why the wheel and the individual pelton shovels are united to one part? Till now I only saw the shovels as separate parts that can be exchanged when damaged.

[@wroarrrrrr]

+Bouregard3 yer+s there is reason.When the runner is made from one part is moore compact.When the shovels are welded or screwed on whell can came that the one ore moore shovels are separated from whell and than is big problem i saw wen screwed sholve get thru the body of runner and thru the wall.Total disaster.Sorry for bad english.

Excellent video. I operate a humble 3ax Busellato & Onsrud woodworking CNC. I had to pass on an offer for operator at a shop machining parts for space shuttles, and aerospace for NASA due to the 4 hour commute to York Co. Virginia. It would have been very interesting.

[@nguyenthoai1126]

How long are you milling this profile pelton turbin ? Can you tell me about the materials for manufacturing a pelton runner ?

[@wroarrrrrr]

cca 600 hours thanks for comment.

[@tomahan044]

wow! never thought these things were made from a single piece of metal ö

[@wroarrrrrr]

yes from 1.4313 niro material

[@squal911911]

Whats that 'box' thing that is mounted on top of the spindle?

[@wroarrrrrr]

+Steven James it is connect for spinde speeder i can hawe 9600 rpm.

[@debitio4979]

Lindo trabalho, qual software você usou para a programação. Teria como disponibilizar o pós processador, para utilizar em fins acadêmicos.

[@Compuengine]

how many axis have this machine, and what kind of cnc is, horizontal machine center or Boring machine?

[@wroarrrrrr]

heloo machine have 4 +1 axis its horizontal boring mill typ Wotan Rapid 1 controller is Heidenhain TNC 530

[@saprtag3798]

Hello . What tool is used for milling of stainless steel Material 1.4313 . What CAM program programming . As you machines - WOTAN RAPID - 1 and CNC TOS WHN 10 CNC the pros and cons ?

[@wroarrrrrr]

+Sapr Tag Heloo Toll for roughing is hitachi for finishing is pokolm wotan hawe aerostatic guideways and hydrostatic spindle bearings i hawe Tos 10 cnc is great maschine but wotan is moore precise and stabile by haewy milling and moore pracise for finishing guideways on wotan cant be damaged because of aerostatic. Cam program for machining is Cimatron better of cimatron is only Tebis.Tebis is the best cam - cad on the world at that moment. Thanks for comment - apriciated.

[@saprtag3798]

Thank you .

[@TonyHoang99]

nice work and well done bro..

[@selimpektas8819]

What is the cutting edge brand and forms that you use? What is the coating of the cutting edge? thank you.

[@wroarrrrrr]

+selim pektaş For HSC milling head i used HITACHI inserts for niro, round inserts are Pokolm and Aura the coating is TicAln.Thise inserts costet 19-22 eur/insert.All other tools dont work in 1.4313 or 1.4317.

[@nhoncolau1384]

Ở Việt Nam ko thấy gia công loại cánh gáo này nhỉ

[@saprtag3798]

Какой инструмент использовали , CAM ? .

[@wroarrrrrr]

+Sapr Tag Heloo can you tell me in english thanks.

[@Squat5000]

+wroarrrrrr I think he is asking which CAM software this was programmed in.

[@wroarrrrrr]

+Vladimir Yushkevich Tebis is the best but that was programmed with Cimatron 12.

[@wroarrrrrr]

+Vladimir Yushkevich Jes i like to use tebis but than i need cam and cad and 5 postprocessors.Thats a litle to much for me the tebis is no1 but i must live with that i hawe in Slovenia-Ljubljana are taxes wery high ab netto 100 eur is my 25 eur tahts 75% taxes for hmmmm i dont now what but so is.Thanks anyway-apriciated.

[@lcteixeira2005]

how many hours were milling?

[@wroarrrrrr]

Heloo cca 600 hours milling

[@space7737]

Hello, how many took the time production of the part. The program themselves were and are interested in binding to the part of the working ground, several installations must be alignment of parts. Thank you, very professional job.

[@wroarrrrrr]

+space7737 The time of production just milling is 600 hours cca.There is 3x clamping 2x vertical and 1x horizontal.If is that answer you wont im bad in english.Thanks and bye.

[@cnccarving]

that was a big chunk... I see started with 1352, what was on the end? how much you removed?very imp[ressive..

[@wroarrrrrr]

+cnccarving The weight at the end was 285 kg and material is niro 1.4313. Thanks for comment -apriciated

[@muhammetyldz1899]

Cad cam program????

[@thelamb288]

The CNC programming must have taken days!? Did you test it on some scrap first? Cheers.

[@wroarrrrrr]

Heloo no i started directly on true material.Program was cca 80-85 Mb.

[@thelamb288]

wroarrrrrr That was brave. Well done. Cheers.

[@FlorianTOSCANI]

Is it a usable part or only for exposition ? If it has to be used, I wish the maintenance guys a lot of patience and a bit of luck as buckets are not removable... Otherwise, thanks for your sharing of this unexpected machining video ;) and thumbs up for the programming and machine / raw material and tools setup.

[@wroarrrrrr]

It is usable part for small hydro power plant.And thanks for comment.

[@FlorianTOSCANI]

Thanks for your reply ;). And, you're welcome (i'm a machinist too, even if it is not on the same kind and size of machines).

[@1220msouth]

Very Impressive for the material

[@wroarrrrrr]

Thanks

[@Clawhammer2002]

Impressive work! How long do the inserts last?

[@wroarrrrrr]

Clawhammer2002 heloo for roughing i use hitachi high speed millin cutter insert time cca 1h for finishing i use pokolm round inserts insert time cca 5h beter to mill dry for finishig.And thanks for your comment.

[@Offender666]

Nice work! Whats the total machining time approximately?

[@wroarrrrrr]

+Factologist Heloo cca 600 hour of continuous milling.

[@bowtie-man]

+wroarrrrrr absolutely and totally amazing. About what does the finished product cost? What happens if there's an oops oops? Congratulations on a quality job

[@wroarrrrrr]

mr.18436572 There is no place for oops,oops.when that came than is 1532 kg material1.4313 destrojed and material costet 8700 eur.Maschinning time is cca 600 hours..so you calculate how much the finished part costs.Thanks for comment-apriciated.

[@tubbytimmy8287]

I bet the program weighed more than the part...

[@wroarrrrrr]

+TubbyTimmy 12 programs for part 80mb.

[@budzab]

No Sumitomo tools from bts? :D

[@wroarrrrrr]

+budzab No no Sumitomo no Sandvik no Seco no Ingersoll no Iscar etc.

[@squal911911]

+wroarrrrrr Then what kind of tooling did you use?

[@wroarrrrrr]

+Steven James Hitachi,Pokolm and Aura all other is crap for this material.

WOTAN RAPID - 1 PELTON RUNNER MILLING

[@flouserve]

No entiendo el porque se hace esta pieza por arranque de viruta, cuando la microfusion es lo ideal.

[@wroarrrrrr]

+flouserve heloo can you please in english thanks.

[@fortxuzopozopi3692]

Todas las piezas por arranque de viruta suelen tener mas resistencia a la traccion y otras caracteristicas. De todas maneras hacer el molde...tampoco seria facil

[@flouserve]

A ver, Calder lleva la tira de años fabricando este tipo de turbinas y siempre se han hecho de fundición, eso de lo del molde, aquí es lo de menos, ya que no creo que esta pieza sea más resistente que la fundida, pero vamos que para gustos los colores y no creo que sea más rentable el arranque de viruta que la fundición.

[@fortxuzopozopi3692]

Esta pieza es mas resistente que la fundida aqui y en la luna. Supongo que habra turbinas pelton que no necesiten de traccion, torsion y elasticidad y puedan ahorrarse el mecanizado, Que siempre es mas caro, por supuesto. Pero nadie paga 600 horas de mecanizado sin haber mirado antes otras opciones.

[@flouserve]

Entonces y según tú , hace 25 años como se hacían las turbinas de este tipo? …

[@AmenofisFikke]

600 hours! :)

[@wroarrrrrr]

+AmenofisFikke yes 600 hours on horizontal boring mill 400 hours on 5 axis maschine.

[@lcteixeira2005]

é lindo

[@КонстантинКолин]

Неремонтнопригодно.
