the rotor of screw pumps production process!

[@WarwickMalone]

I feel a great regard for my fellow man knowing he has created such machines.

[@fritzgutten1]

a bit of explanation besides "whirling" would be nice.. how is the depth of cut set? just a manual tool offset?

[@williamhoward8319]

my first time seeing this operation is fantastic

[@tireballastserviceofflorid7771]

This style of pump is used by Moyno pumps. We used them at Kraft foods for tranfering products. Used extensively in individual wrapped slices of cheese. I have seen tue produce 350psi several times. Never intentionally. Usually ren 40 to 60 psi and a surprising volume. The stators are made of basically tire rubber inside a stainless steel tube. They wear out but it can last up to a year in that environment. Very interesting and reliable pump.

We had those pumps underground in UK coal mines. My job was to service them. Basically the rubber outer wore and would be replaced but the part seen made here would last many years. I'd always thought they were forged to shape.

That is rotor for NETZSCH system of pumps. I made one on conventional lathe machinein about 60 minutes + about 60 minutes preparing. L ~200mm, D~30mm, excentrecitet e=6mm, l ~60mm. Material 12X18N10T. It was on 1986.

Really? Thought they would manufacture those rotors inhouse?

[@manasTIR3707]

@@Tom_0815 What is not clear? Do you know NETZSCH MONOE pumps?

[@whirlingmachine113]

great ! NETZSCH is a very professional screw pump manufacturer and has cooperated with us.😀

I have a worn one of these as an ornament.. a thing of beauty..

What's the cost of machine sir

[@Echo7Kyle]

What’s this type of cutting process again? It’s not skiving I don’t think. Beautiful work

[@JohnSmith-dp2jd]

There might be a different name for it once it gets that big, but it looks a lot like thread whirling. The cutting head is off-center and tilted to match the pitch angle of the thread or helix being cut.

Says 1 time cut on the screen.

[@istvankiss5712]

Why not refrigerate? Am I the only one who doesn't see the coolant?

[@ipadize]

what do you want to refrigerate? 😂 no these insert tools better run dry because of thermal shock. When it cuts and gets cooled over and over again it can break prematurely, though the surface is better when using coolant.

[@whirlingmachine113]

you are right ,it is need coolant for processing, so I turned off the cooling system to get a better shot.

This was the most boring video I saw this month.

[@marcusrauch4223]

What did you expect of a machining video like this?

[@Stefan_Van_pellicom]

@@marcusrauch4223 Some editing, some speeding up of the monotonous bits, some explanation on the cutting process, some explanation on the Y-axis shift, etc.
