Title: Arbors again
Post by: Darren on July 23, 2009, 12:35:04 PM

Can someone please tell me how this cutter is held in the arbor, is it simply threaded in... :scratch:

That looks like a V belt drive could be from a subsidury drive shaft set up someone has cobbled together  :scratch:

Puzzled

No Stew,

It's a BT30 auto change milling arbor that will with a little adaption fit my mill spindle, I was just wondering how the milling cutter was fixed?


Nice idea though.... :thumbup:

ps, I only know that cos Mr Stevenson told me.... :smart:

Ho the the V groove is for the auto changer I see, not into machining centres that much, from the pic the cutter looks intergrall with the arbor, is there a long screw up the bottom, or through the cutter bit, try unscrewing the cutter left hand  :scratch:

Still puzzled

Sorry Stew I'm confusing you again, I don't have one, just wondering as I see some on ebay.

I don't want this type if the cutter can't be replaced......that's the real question.... :scratch:

Woops

 :doh:

I'd thought you'd got one sorry can't help with that, no idea how they are fixed, I bet someone will know on her though.

No idea, never seen such a thing! :med:

However if it is threaded I would expect to see some flats or something so it could be gripped for unthreading... :coffee:

Shrink-fit?  Some high end tools use that method, though this doesn't really look like one.

These are one piece production machine tools. I you break one, the whole thing goes to scrap.  ::)

Thanks for clearing up that mystery, the chaps selling them off could have picked them up from a scrap pile, you'd have to be carful buying one.

Cheers
