Hi I am building a small (1200mm x 800mm or 48in x 30in) cnc router for hardwood, to produce parts such as patters for castings for internal use. I am trying to select a spindle and the only experience I have is with very large spindles from my grad school research (12 hp) so I could use some practical advice. I am looking at ER20 and ER25 size spindles with between 1 to 2.2 kW, probably 300Hz.
I am trying to figure out how much of an advantage ER25 would be (being able to run a large diameter endmills such as 15mm or 16mm) and is it worth the larger and heavier spindle. Also if I am running those sorts of end mills I need more power to really make use of them which makes everything heavier and more expensive.
I am not interested in some junky chinese spindle and am looking at the German and Italian options such as Teknomotor, Elte, HSD. So that would be square body manual tool change spindles, probably air cooled. I would like something with tool holders but for the application really can't justify the added cost.
Any suggestions, advice etc?
thanks
Luke
