O/T Rolling Threads On CNC Lathe

[CAM-mando]

I searched and to my suprise found very little on the subject here.

 

I have a part that we have made thousands of. The customer is now requireing rolled threads. The material is 416 Stainless Rc 28/34. The thread is 1/2-20 UNJF.

 

Does any body have experience rolling threads on a CNC lathe. I am considering an axial type rolling head. Any suggestions on manufacturers, cutting fluid, or other relevant experience would be appreciated. I did find a very informative article on MMS online for anyone interested it is HERE

 

Thanks

Thread rolling is an excellent productivity boost. I used a Fette Axial unit on 3/8" and 1/4" 316 Studs and made a forturne. As we only used coolant, the life of the rolls was a little shorter than we would have liked but even still, the savings over single point were substantial.

 

There are also systems available from Winter and Landis.

 

Screw Machine Suppliers will have more information for you - Stainless roll flows real nice and there is some technical assistance that the manufacturer will provide to help you optimize your process.

 

Good Luck

Cool link CAM!!

 

In the article it mentions rolling Acme threads, that would be something to see.

We use to get a 2" 2 lead acem done back in Florida for the paper industry. It was 110 of full thread. I said i another thread about the Naval brass and the more think about I want to say it was rolled but could be wrong but they were some awsome looking threads.

Thanks Guys.

 

Andrew I talked to Fette and they will be coming out to review the application. Sounds very promising though.
