Have your say about this chinese cnc milling machine

[Boyan Silyavski]

6000 rpm, 2,2kW, = 3.5Nm, too small

I am struggling why position accuracy is so low.

I believe this is servo driven spindle, not direct drive but belt and there must be gear ratio also. So 2kw servo is not 3Nm. I remember somebody was looking at building a mill and had more info about the servomotors that go with it. I think it also could be ordered 10k RPM

PS. Ok, i see VFD in the enclosure and 4 servo drives. So probably this is a cheaper version with direct HF spindle
