摘要： This disclosure relates to a metal-cutting machine tool with a base body, which is rotatable about an axis of rotation relative to a workpiece to be machined, at least one plate seat disposed outside the axis of rotation on the base body and a cutting insert, which is inserted into the plate seat and held therein by at least one fastening means and which is provided with a coating, at least in the area of its cutting edge. In order to compensate for positional tolerances, according to this disclosure the plate seat comprises a positioning surface oriented toward the axis of rotation, and the cutting insert has a reference surface lying against the positioning surface and facing away from the axis of rotation, for radially determining the position of its cutting edge, wherein the coating is also applied to the reference surface.

摘要： This disclosure relates to a machine tool comprising a tool holder which rotates relative to a workpiece to be machined and has a tool axis, and a plurality of cutting inserts that are removably attached to the tool holder, the active cutting edges of said cutting inserts having a common cutting circle which is coaxial to the tool axis. According to this disclosure, the tool holder has a cylinder-type insert seat shell for radially positioning the cutting inserts, which rotates about the tool axis. The cutting inserts have at least one contact surface that can be brought into contact with the insert seat shell.
