SHEAR FORMING/FLOW FORMING BY HAND, NOT REGULAR SPINNING.wmv

We are a job shop. Among one of the many things we do is metal spinning. When ever there is a chance for improvement, we try new things. This is good for a short run but don't advise on a regular basis by hand. Just wanted to try putting up something on UA-cam. Normal spinning of this part takes much longer. Hope to put up a collection of things we do. Contact us for more info through our website www.fabricorpro... and see our facebook page for more info at www.facebook.co... Thanks for looking and any comments are appreciated.

Hi, The difference is that regular spinning generally consists of 3 basic operation of reduce, stretch and lay down which can take a long time and takes less pressures.. This way the material is usually kept thicker. With flow forming all three operations are done at the same time and usually will results in thinner material than regular hand spinning and is much harder to control and needing increased pressures.

This also is on the same custom lathe we show the tube spinning on. It's a 3hp varidrive machine with a quick action tailstock.

The wheel shaped at the end of your forming tool it it steady or spinning like a ball bearing
Thank you

It is spinning. There are 2 heavy duty bearings mounted in this roller which is rolling on an axle mounted between a fork end.

Hi, I have no experience in this, but was is different here than in regular spinning?

Thanks can I ask where you got your lathe from im looking for a custom lathe. One that will swing 160"/4000mm doesn't matter about between centres

ran dom Sorry, no ideas.

[@random5147]

[@Goesinya69]

I think you'll find this is actually Shear Forming and NOT Flow Forming.
Flow Forming is a totally different process.

Hi Chris,
30,000+ hits and you are the first one to point this out. You are correct. When this was put up both words were being thrown around and flow was put on the video. Both do entail thinning of the material. Conical shapes are shear formed. Sorry for any confusion. Found this article to help explain differences - archive.today/Tcxsw
