A machine tool head having a spindle nutatable about a center at the front of the spindle and at or closely adjacent to the front face of the machine tool head so that the radial reaction to the cutting forces is transmissible from the spindle to the machine-tool head essentially in the plane of the front face of the machine tool head.

Machine tool head having nutating spindle

A machine tool head in which a rotary spindle is adapted to nutate by virtue of the spindle being mounted in a housing supported to rotate about a predetermined axis and by virtue of the housing being mounted in another housing adapted to rotate about an axis which is inclined relative to the first axis. A train of bevel gears connects the spindle to a non-nutating drive motor and maintains a rotary drive from the motor to the spindle in all positions of the spindle.
