Claim:
A machine-tool turret-type unit for machine tools with a turret disk ( 1 ) free to rotate about a rotational axis (A), and having a housing ( 2 ) within which means to mount the turret disk ( 1 ) are provided, whereby the housing ( 2 ) includes at least one securing device ( 3 ) configured to secure the turret disk ( 1 ) to the securing section ( 4 ) of a machine tool, characterized in that the securing device ( 3 ) includes at least one generally planar securing surface ( 3 a ), wherein the at least one generally planar securing surface ( 3 a ) lies within a first plane (XY) and is configured to rest against the securing section ( 4 ) of a lathe, wherein the attachment between the housing ( 2 ) and the securing section ( 4 ) occurs within the at least one generally planar securing surface ( 3 a ) lying parallel to the first plane (XY) and within which the rotational axis (A) of the turret disk ( 1 ) is mounted, whereby the rotational axis (A) of the turret disk lies within the first plane (XY) and when heated, the housing ( 2 ) expands outward with respect to the at least one generally planar securing surface ( 3 a ) and the rotational axis remains within the first plane (XY).
