Hi I'm putting together a 3-axis mill to mainly machining aluminium. This is my first machine and I may have gone a bit overboard with the spec(C1 XY, C3 Z ground ballscrews, THK HSR25 rails, 400W Yaskawa AC servos all of ebay).
So far I've spent $2200 and I expect to spend around the same again to put it together (excluding spindle and VFD).
I was originally planning to use a Teknomotor 1.6KW with DC Fan as the spindle but I can't seem to find much information in the forums on how well they actually perform in real life which makes me a little nervous.
A new unit mentioned costs around $1000, but I am now wondering if I should not be spending more towards the spindle considering the rest of the machine?
Anyone have any thoughts?
