Auxiliary Highspeed spindle

[stefang]

Hi Folks,

once again, all my current projects came to a stop, because I wanted to build a tool (to build other tools, that will build other tools, ...you know the drill )

This time its Jerry Howells Highspeed Spindle:
http://www.model-engine-plans.com/engineplans/bookshelf/millspindle.htm?47,17

I ordered the plans, and started building...this is the result:

I modified the design to accept the small steel collets from the Proxxon Micro-Powertools (Almost like the Dremel ones, but made of hardened steel and ground)

Fits into a 20mm collet, the motor is a cheap size 540 Type, but I am looking for a DC Servo with a bit more grunt.

Tested it with an ATX Pc powersupply, works great for engraving and endmills smaller 2mm.

Here a short video (bit blurry):

And the result:

(If you wonder, "CNC-Ecke" (cnc-corner) is a german forum about cnc/manual machining...)

greetings
Stefan

hi stefan, very well done job there

I like this tool, my mill doesn't go over 1500 rpm and this one seems to be a neat solution to overcome the problem

another tool on the neverending list of 'to do'

Hello Stefang, listen to an engine that you used, what equipment did you get it from? Hello Vincent.

Thanks a lot

another tool on the neverending list of 'to do'

Yeah, but this thing can be done in one evening

listen to an engine that you used, what equipment did you get it from?

The motor? It is a store bought motor, generally used in rc cars, cordless powertools, hairdryers, etc..

greetings
Stefan

Nice job Stefan!
My Dremel pantograph uses what looks like the same chuck. I don't use it often but when I want to I can do small detail stuff. With the CNC you have there's no limit to what you can do other than yor imagination.
Regards,
Rich
