Abstract
The invention relates to a cutting tool comprising a main part which extends along a longitudinal center axis or rotational axis, at least one cutting insert holder mounted on the main part such that it can be radially adjusted, and an adjusting device for adjusting the position of the cutting insert holder relative to the main part. The adjusting device comprises a threaded sleeve which is non-rotatably but axially movably mounted in the main part and a screw drive driving the threaded sleeve.
Claims20
Cutting tool comprising a main body which extends along a longitudinal central axis or axis of rotation, at least one cutting insert carrier arranged radially adjustably on the main body and an adjusting device for adjusting the position of the cutting insert carrier with respect to the main body, the adjusting device comprising a threaded sleeve arranged non-rotatably but axially adjustably in the main body and a screw drive driving the threaded sleeve, the screw drive comprising a threaded spindle and a bearing bushing, the bearing bushing is held non-rotatably in the main body, the screw drive is formed from a differential threaded spindle, the threaded spindle is screwed with a first threaded portion to the threaded sleeve and with a second threaded portion to the bearing bushing, and the bearing bushing is connected in an axially tension-proof/pressure-resistant manner to a piston which delimits a pressure chamber in the main body.
A cutting tool comprising:
- a main body which extends along a longitudinal central axis or axis of rotation,
- at least one cutting insert carrier arranged radially adjustably on the main body,
- an adjusting device for adjusting the position of the cutting insert carrier with respect to the main body, and
- an actuating element,
- the adjusting device comprising a threaded sleeve arranged non-rotatably but axially adjustably in the main body and a screw drive driving the threaded sleeve, the screw drive comprising a threaded spindle screwed with the threaded sleeve, the threaded spindle can be actuated on a front face of the main body,
- the actuating element held rotationally movably but in an axially fixed manner on a front end of the main body.
A cutting tool comprising:
- a main body which extends along a longitudinal central axis or axis of rotation,
- at least one cutting insert carrier arranged radially adjustably on the main body,
- an adjusting device for adjusting the position of the cutting insert carrier with respect to the main body, and
- an alignment device,
- the adjusting device comprising a threaded sleeve arranged non-rotatably but axially adjustably in the main body and a screw drive driving the threaded sleeve,
- the alignment device arranged between the cutting insert carrier and the threaded sleeve for radial positional adjustment of the cutting insert carrier with respect to the main body,
- the alignment device comprising a threaded bushing, an adjusting screw and a pressure element,
- the threaded bushing integrated in the cutting insert carrier,
- the threaded bushing having a radially elastically deformable wall segment,
- the adjusting screw screwed to the threaded bushing and supported on the threaded sleeve with its end projecting from the threaded bushing,
- the pressure element arranged on the cutting insert carrier, the pressure element configured to be screwed in the threaded bushing to press the radially elastically deformable wall segment against the adjusting screw.
A cutting tool comprising:
- a main body which extends along a longitudinal central axis or axis of rotation,
- at least one cutting insert carrier arranged radially adjustably on the main body,
- an adjusting device for adjusting the position of the cutting insert carrier with respect to the main body, and
- a compression spring,
- the adjusting device comprising a threaded sleeve arranged non-rotatably but axially adjustably in the main body and a screw drive driving the threaded sleeve,
- the screw drive capable of being displaced axially by a piston which delimits a pressure chamber in the main body,
- the compression spring between the threaded sleeve and the screw drive,
- the threaded sleeve and the screw drive are threaded with respect to each other at regions of threaded sleeve and screw drive that are coaxial relative to the longitudinal central axis.
