Spindle head for a universal milling machine

A universal milling machine comprising:

• a round table rotatably supported on a highly stiff machine bed for accomomodating a bulky and large workpiece;
• an effective rotational drive for the round table capable of rotating the workpiece at several hundered rpm for performing turning operations;
• a machine column comprising a slide shiftable on the front side along two coordinate axes by means of a motor;
• and
• a spindle head provided on the front side of said machine column so as to be rotatable about a horizontal rotation axis by means of a motor, said spindle head comprising:
• a machine part shiftable on a machine column and an elongated first housing mounted on the machine part so as to be rotatable about a first axis;
• a directly driven first work spindle having a second axis and being mounted axially parallel in the elongated first housing for carrying out roughing and finishing operations on the workpiece set up on a workpiece table;
• and
• a second spindle unit adjustable about two axes disposed on the end side of the elongated first housing opposed to the first work spindle, said second spindle unit comprising a second work spindle provided in a spindle housing, said second spindle unit further comprising a drive motor, said second spindle unit comprising a fork head rotatable about a rotation axis, the spindle housing of the second work spindle being supported in the forks of the fork head so as to be pivotable by means of a second motor about a third rotation axis, the rotation axis of the fork head extending parallel to the second axis of the work spindle and laterally offset with respect to the housing.
