    Patent number: 3955257
    Abstract: A turret head for a rotary turning machine having a base rotatably mounted on a cross-slide for movement about a first axis. The turret head is mounted to the base for rotatable movement relative thereto about a second axis that is inclined to the first axis by an angle .alpha.. The turret head includes two rings or annular arrays of tool holders. Each ring has its tools disposed so that their axes lie on the surface of an imaginary cone having a vertex angle of 2.beta., such that .alpha. + .beta. = 90.degree.. The two imaginary cones have their axes coincide with the second axis and preferably the vertices of the cones coincide, so that the cones are mirror images of each other.
