Hi , i have a denford triac atc ,im going to give it some love . i currently have it running with a 24000 rpm water cooled spindle geared down . 5/6000 rpm is good when cutting aluminium which i mainly do . But i would like to cut steel at lower rpm . this spindle loses all torque at slow speeds.
I've recently retired so i have time now for an upgrade . i would love to be able to tap, cut steel and aluminium at reasonable rpm . so is this a pipe dream and i have to have 2 machines or is there a motor/setup i can use that will do a half decent job and not be extremely expensive .
im quite prepared to build a new spindle motor mount as i have some hiwin linear rails for x,y.z i have already bought .

cheers
