ABSTRACT:
A spindlehead for a horizontal boring machine is disclosed. Included is a spindle sleeve mounted to a spindlehead casing for axial displacement out of and into the casing. A spindle is rotatably mounted within the spindle sleeve for joint axial displacement therewith. A spindle drive motor is geared to the spindle in order to drive the same for required boring or like operation. Another motor is employed for feeding the spindle into work along with the spindle sleeve and the spindle drive motor. Being fed with the spindle sleeve, the spindle is thereby rigidly supported even when extended out of the casing.
