we are planning to retrofit our old Vertical Turn-Mill with Siemens 840D. The mill spindle of this machine gives only 1000 RPM (max) and so we have a problem with cutting speeds (and feeds). We would like to replace this with a full CNC B-axis add-on to the spindle. This accessory is made by several companies. But this wont solve our problem of low cutting speeds. We would like to have a B-axis with electro-spindle. Does anybody have such an accessory?
