How was this Aloris AXA tool post hub made?

Yan Wo · Nov 24, 2019

This is the hub of the new-to-me Aloris AXA tool post I recently bought.

When I disassembled it to see how it worked and to clean it, I was surprised to see the depicted hub was apparently not machined.

How was it made?

It is very hard. A high quality new file just skates across its surface.

I'd call Aloris up and ask them. There is a good chance that they'll just tell you.

It could be a powder metal part, but since its an old design my guess is "plain old lathe job".

It does look like powder metal to me as well.

I'm gonna go with pm as well...you can harden the piss out of some of the compositions right from net shape winter.

What makes you think it was not machined? If it's just the surface finish looking a bit pebbly instead of smooth and machined, that could be because it was tumbled or vapor-blasted or something, perhaps as a scale removal step after heat-treating.

There's nothing on that piece that can't be machined in conventional machinery.

Doc.

Good point. I realize it can be machined, it just doesn't have a nice smooth crisp machinee look.

There are faint tool marks, and they do follow the threads, so maybe it was machined.

By the way, the thread is left-hand triple start, which is very cool, I think.

I shall do so. Thanks for the suggestion.
