Auction finds

[p0689109]

I picked these up at an auction Friday. The first 4 pictures are of what was called a collet set. Any ideas what these are for?

They're a collet set!

They are for holding different sized cutters in a milling machine. Looks like MT3 shank.
Last one is a bearing puller.

 

[Tigman]

the last picture is a puller ! pull off pulleys and such

 

[rikrobson]

The collet set is a collet set. morse taper chuchk two spanners and some collects look like er25 or er16

Collects hold small stock in lathes or for holding end mills. Think of them as accurate drill chucks


The other kit is a puller for getting hubs off or gears off shafts

 

[MattH]

There not ER, maybe Clarkson autolock but can really tell from pic.

But deffinetly not ER.

 

[rikrobson]

you're right matt I was looking on the phone earlier, they are not ER collets

 

[brightspark]

there not Clarkson autolock

 

[500e]

Definitely to short for auto-lock

 

[AdrianH]

I think it is a Clarkson auto-lock chuck, but the C type with this type of collet



This was the older style before the S.

Still out there, the whole thing looks like this one on the bay


The above is MT4 and MT5 item number

yes ive got the s type with flats on the collets

 

[graffian]

Pictures pretty bad. Looks like DA collets to me, not that I have ever seen a DA collet;-)

 

[daleyd]

The bearing puller looks pretty meaty - is it hydraulic?

 

[p0689109]

Sorry I forgot to add the name of the collet set. It is Clarkson autolock but it seems incomplete compared to Adrian H photo. I knew the last one was a puller as mentioned in the initial thread as the question was about the first 4 photos! The collet set is available if anybody can use it. pm me if interested. The puller set is actually incomplete in that the large centre piece, which is hydraulic, does not have its matching attachment collar that screws on to it. The one in the box is just a three piece band clamp. I should have inspected the tool more keenly before I left a bid but that's life. I have another puller just like it and if it is the same I will have a spare! Thanks for your inputs lads.

 

[AdrianH]

The collet sets typically came with 4 collets, either imperial or metric. Looks like the box held 8 so typically both Imp and metric were there at some point.
The picture I posted shows two sizes.

Unless you are missing an internal piece? then not sure what is missing. Perhaps separate everything out and take a better picture of all pieces?

Relooking I have only one taper chuck and it looks the larger of the two in the pick. Find better photos below.

 

[MattH]

That's complete, what more do you want?

 

[AdrianH]

Assuming the 5 means MT5 then yes you seem to have a complete set up.

There are tables here http://littlemachineshop.com/reference/tapers.php to confirm the taper.

When these are used in a milling machine it does not have a tang on the end but a threaded hole as you have in the end, could be something like a 1/2" UNC or similar.

There were 4 spare holes in the storage box and the taper shaft has a screw thread in the narrow end and was wondering what it was for. I actually don't want anything but info!

 

[MattH]

As Adrian says, the thread is for the milling machines draw bar. These are usually supplied with metric collets or imperial collets or both. Hence 8 holes but 4 collets.
