There goes the €3000 savings right there :)

RotarySMP:
Your numbers add up to about a 650kg frame. What are you travels?

It sounds like your machine plan might be a little light. If it is about 180cm tall, it would be in a class where the industrial CNC machines are normally well over a ton. More like 2-5 tons if they designed for high dynamics (which your 1.5kW servos would imply).

Ok, i got it to about 825kg actually. But yeah its a bit on the light side actually.
And that something that have been a concern of mine., its about 1500mm from top to bottom.

The travels is
z: 425mm
x: 450mm
y: 450mm

And the motors, and screws would put the machine somewhere in the 500ipm atm, thinking of gearing the axels with belts and push about 1100ipm - not entirely sure if thats possible tho.

Mainly out of curiosity. And secondary because i exhausted ways of getting a 1-1.5t cnc machine into my shop by, just buying it.

Thanks, that clears up a lot.

Hi Neotech,

I found my post in the Monster CNCzone E/G :
http://www.cnczone.com/forums/epoxy-granite/30155-epoxy-granite-machine-bases-polymer-concrete-frame-8.html#post245588

This summarises a book I got out of the library.
