use soapy water

[rinato]

Hello gentlemen, easy question:

in "schindler's list" there is a scene in the schindler factory where you see that they print pots lubricating the funnel mould with soapy water (the guy with a lower arm etc...).

Is that a method you really used?
is it effective?
Is it still used?
are there technical parameters, possibly?

Thank you, reborn.

from a very fast web search it seems that you use some emulsion water/oil more than soap

Who knows why I came up with this video

from my father's stories, the turning point of those "of a time" soapy water was also used in mechanical processing in case of particular materials.
Now I don't remember what these materials were but I'm sure it was used.

ot: that Chinese video deserves a passage to venetian or, better, to cannes ( ;-) ) to receive a special prize of the jury.

in turning work is used emulsified water which is a mix of water and specific oil.
to cool the tool and lubricate the contact surfaces.
Now with the inserts it seems to me to be used in finishing phase and with very ostic materials, but when I started in school (initiated years '90 ) using tools in super fast and very rare case in widia balancebrasato 8solo for those good ones... so I saw it from afar), emulsified water was always used.

Beautiful video, I saw it a few years ago.

it is also used in roughing

I remembered. When I was grinding medium/heavy on forged steels I don't remember ever using emulsified water, then maybe sometimes it happened with sneezing materials... My memory rhymes me against.

I ask not because you do not already use the emulsified water both in molding and in lav. mecc. various (or is the oil to be emulsified...), but because we print pieces that need internal oil, and the customer complains of the resulting untuosity, but does not want to pay the washing.
and since I have a twisted mind, and that film I remember it also for that detail there, I asked if the soapy water still has some technical relevance, because it would allow me to perform possibly only a rinse with simple water instead of a complete washing.

well aware of the fact that between "the whole" and "the soapy water" is half a known universe. . .

part to 2:25 is hallucinating...and here I read your calculations on bending resistance, cutting etc.

...I wondered if the soapy water still has some technical relevance, because it would allow me to perform only a rinse with simple water instead of a complete washing. . .

so it is clearer, I can't tell you

 

[stevie]

I think the only chance to verify is the use in the specific application. . .can work but clearly not with comparable performance to anti-friction fluids.

paradoxically some craftsman returned to soapy water with excellent results. in the industrial field you try not to use anything that is not accompanied by a technical sheet, because each process must be standardized. However, simple, not patentable solutions have been used in their elementary state for over a century in the field of cold deformations and are metal stearates, such as calcium, magnesium and zinc stearate that are dry lubricants. However, to think about it well, soap is nothing but hydrolyzed stearina. there are also spray products for dry lubrication (I just bought one for a laboratory test); I did not control the composition but I hope it does not contain derivatives of the pfos, which would be a great anti-stick but I believe and hope it is now forbidden.

Here, see what's going on! I'm sure I can blame the proff at the time. )
It will mean that as soon as they clone me, I will have time, way and reason to do practical tests.
