Abstract
The invention relates to a tool holder for use in machine tools, comprising a main body, which can rotate about an axis of rotation, and cutter holders which each hold a cutting plate and can be radially adjusted by means of an axially displaceable control rod and coupling means. In order to further develop said tool holder so that it is possible, within a very short time, to produce a turned groove which satisfies stringent demands regarding surface quality and geometric roundness, it is proposed, according to the invention, that the tool holder has at least two cutter holders which can be radially adjusted between a retracted position and an extended position and whose cutters can be simultaneously brought into engagement with the workpiece in order to produce a turned groove.
Claims24
A tool holder for use in machine tools, comprising:
- a main body, which rotates about an axis of rotation,
- at least two cutter holders which each hold a cutting plate and can be radially adjusted by means of an axially displaceable control rod and coupling means between a retracted position and an extended position, and
- gear means for converting a rotation movement of the main body into an axially oriented reciprocating movement of the control rod,
- wherein the at least two cutter holders are disposed about a common circumference of a circle and their cutters can be simultaneously brought into engagement with a workpiece in order to produce a turned groove.
