Circlip grooves

Ummmm - with internal circlip grooving tooling maybe?

-- Dave Baker

Grind a boring tool tip to that you require for the circlip.

Well thanks for that snippet of advice. A fresh Google turns up nothing for the armature.

Of course you could always advise on a reasonably priced source. Many thanks. John.

Usually the simplest way is to convert a boring tool of some description to basically an internal parting tool.

It's a bit of an open ended question not knowing what tooling or machine you have. Something like these generic holders can accept small HSS bit home ground to any shape, boring, internal screw cutting [ all forms ] and grooving.

go to

Application Case Studies

Then on Internal grooving 1/2 which should take you to a page with a long list.

click on this heading ....Super Mini - Internal Grooving - Motor Sport and Defence

Which should give you this page.

I don't do this very often but have made a few internal groove tools form 1/4 and 1/2 inch square section HSS blanks than can be held in the toolpost.

Also you can use old broken endmills or slot drills in a boring tool holder in larger holes. Use the parallel shank from broken slot drill with a ground flat for the grub screw to tighten on in the tool holder. Grind the end like a part off tool, lots of clearance underneath to clear the side of the hole, especially small holes.

Maybe your Google is deficient as it seems to provide an elegant sufficiency when that term is used.

Of course you could actually provide some specifics as to what range of dimensions you wish to machine. Smaller diameters cannot be machined with the style of tooling that can be utilised on bigger diameters. ie Tooling that has either replaceable tips or inscrutable tool steel.

I always have the tool upside down and take the cut at the back of the hole. That way you can at least see whats going on. I quite often use an upside down tool in the rear toolpost for boring holes as well.

Hey guys. Many thanks, at least I have an idea what kind of tooling I need to get the profile, will see if can scrounge some old endmills (small enough) or an old boring bar.

Time to rummage in the scrap bin :-) John.

Oh, so you're trying to repair an electric motor. Should have said so in the first place.

"Grooving tool" gets 239,000 hits on Google. Is that not enough? Even "circlip grooving tool" gets 264.

PS - top posters usually go straight into my killfile.

You have to remember to turn it off first?

But if you don't, you don't need a lathe ?

Good point well made!

I find it incredible that, Gareth 'loony bin arrested for internet stalking' Evans still can't handle the basics of newsgroup posting.
