Miller cutterhead with two continuous rotations and direct drive, of the kind that is comprised of slide, cutterhead and main spindle, where: a)-. the cutterhead is a modular element and has a first and second supplementary rotation spindle, to convert a three-spindle grinding centre or milling machine into a five spindle one; b)-. it has a first motor coupled directly onto the first supplementary rotation spindle with the stator fixed on the slide and with its motor fixed on the cutterhead; and c)-. it has a second motor coupled directly onto the second rotation spindle. The first and second motors are high torque flat motors with a low speed range; in particular direct servomotors, without any intermediate transmission or reduction. Application in machine-tool.
