bt35 collet chucks for denford triac

[m_c]

I think a servo would be overkill for a toolchanger!
Small stepper and driver would be far cheaper, and just as effective, as you don't need high acceleration or speed, unless you want to spend your life putting the tools back in the disc...

The mishmash of collets I seem to be gathering is what will probably push me to either buying a batch of BT35 ER toolholders, or swapping the spindle. When I need to swap tools, I seem to spend longer hunting down collets, or having to swap tools around to toolholder/collet combinations that will work for what I'm trying to do.
I seem to be managing fine just now, but I've not been using my Triac that much. I do have some new products on the sketchpad though, which are going to require a re-think of tooling, as I don't want to lose time having to swap tools between holders.

Looks like only three parts are different, but I'd probably renew everything internal to the spindle. It will also likely need new taper bearings, as I doubt they'll come off the old spindle without damaging them.

cool- il take a look.
re servos- not a problem here. i service and repair mitsubishi servos. hundreds in stock from 50 watt to 5kw sizes
also stocking allen bradley drives etc for those that need something with every function known to man! ( used on the triac to run the original fanuc red cap motors.)

Yeah.
I think you could machine a Triac head to accept one, but mounting the motor could be a challenge, and you'd add a fair bit of weight, which I don't think would do the dovetails much good long term.
If I was scratch building a machine, one of those, or something very similar would be top of the list.

I managed to buy 10 nice nikken collet chucks
Take the expensive km22 collets. But they are very nice!
£35 each with collet.

Care to share your source?

I've got various searches setup, but I've not seen any BT35 for sale for a couple months now.
