MACHINE FOR MACHINING BODIES OF REVOLUTION Russian patent published in 1994 - IPC

FIELD: machine tool manufacture. SUBSTANCE: machine bed is made solid from a high-filled composite based on polymers in the form of a closed portal which upper horizontal part has a trapezoidal cross section, and guides are positioned on the side surfaces. A blank fastening device is made in the form of a clamp chuck which axis is equidistantly spaced from the upper and lower horizontal parts of the portal. Carriages with tools which may operate together or individually are positioned on the guides. Cutting vibrations are damped by the bed material which deformation is minimum.
