High production mill threading

[Incogneeto]

Hi Guy's,

Anyone have any ideas on high production threading. Really don't want to thread mill due to operator inexperience. I'm threading two 1 1/4 -16 UN 2A bosses bout an inch deep

Am checking Die Heads but they are pricey. Anyone got ideas it's cast aluminum. how long do you think a thread mill will last before breaking down?

I don't think it would be an issue at all. We just ran 152 holes (.4375-16UNJS) in Ti. We will run this cutter in another part.

I believe threadmilling will be a lot less expensive as well as safer than using a die. IMO, It will last at least as long as your die.

      ^{Well for me thread milling is the way to go, a good carbide multi flute mill for aluminum with plenty of coolant on a 1" diam. would really last a long time on an od thread not re-cutting chips.  Once you get it tuned in should be less than a minute for even two roughers and a spring. Great thing about it is with tool wear you have more control over sizes.}

It will last virtually forever, given proper coolant/speeds-feeds.  Current production run in house 1"-16tpi  .875dp female threads, we have currently run over 1600pcs and have only had to make slight wear adjustments. Zero burrs, and this tool even chamfers the lead in.  FYI this is a single pt. 4fl SCT carbide thread mill.

Can you tell me where you got them?

You can get SCT (Scientific Cutting Tools) through MSC. I personally always use Threadmills USA  (www.threadmillsusa.com)

 

I'm sure you know this but for aluminum make sure it's uncoated.

Thanks ,What do you think about indexable cutters?
