Thread: Parts need turning
-
12-01-2014 #1
Hi
I have 5 parts I need turned. There are 2 cylinders which are pprox. 440mm long and 25mm in diameter. The other 3 parts are approx. 450mm long and 6.7mm diameter. There is very important detailing and threading to be done on 2 of the parts.
Please let me know if you could take on the job. I will provide engineering drawings and 3D CAD files. I could also supply the steel round bar if neccessary.
Thanks

Will definitely need a good quality toolholder mounted travelling steady to get any degree of diametrical accuracy...

1/4" might also be an alternative if you're thinking about using standard stock

Swiss/sliding head lathe, or a roller box would take care of the 6.7mm.

I cant change any dimensions unfortunately because these parts fit into the entire assembly, I'm sure there's room for error but it would be small and difficult for me to estimate. Anyone willing to take a crack at this?

You're going to need someone with a lathe & travelling steady (or sliding head) that can turn 20"+ between centres. Can't think of anyone here, with the exception of maybe JohnS, that has a big enough lathe. What's the tolerance on the 6.7mm?
Also, the 'cylinders' - do they have an internal bore? Or are they solid?
I know someone who has access to a cylindrical grinder, rather than a lathe, that might be able to do the long thin parts as a 'homer'.Last edited by irving2008; 13-01-2014 at 07:55 AM.
