Title: Changing milling bits
Post by: ArduinoNewbie on March 05, 2013, 10:45:46 PM

Hi,

I have had great support from this website and my machine is up and running, than you,

I"m now looking at upgrading my machine to change bits, I'm using a dremel and am really not sure how to automatically change bits, can someone please point me in the right direction.

Thanks in advance

Tool changing is pretty complex and ussually done with tool holders not collets as you have on a dremel. Also they mostly work with hollow spindles so that the release mechanism can be mounted on top.

Hi Gary,
Ohh great, sounds like you know about the Changing bits part of my project.  I have been googling and have found water cooled motors that sounds like the way to go, but I have not clue about the part where to get a head as the motors only come with a shaft and no heads.  Is there a cool website you could direct me to. I would love to upgrade my machine to be able to chage its own tools.

Thank you in advance

How fast do you need your spindle to turn?

What materials are you cutting?

Tool changers on little machines are either home built or really expensive usually.

Just a high speed spindle? Here are pages of them on EBay.

Here is a fantastic build by Joe Vicars.

Usovo's version which I think is also carried by IMService.

   Btw, I ran this one for a while but it would always slip at a critical time (arent they always?) and break the bit or ruin the part, most likely both. It was a simple design and seems like it should have worked. It was a well made piece. I tried all of the different springs etc. I was trying to machine metals not plastics or woods etc.
