Abstract: The invention relates to a cutting tool comprising a main part that can be rotationally driven about a 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 cutting insert holder is mounted in a guide recess in the main part such that it can be moved transversely, preferably radially, to the rotational axis, and the adjusting device has an adjusting element that is arranged such that it can be moved inside the main part transversely to the rotational axis and transversely to the displacement direction of the cutting insert holder and supports the cutting insert holder.

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.

Abstract: The invention relates to a cutting tool comprising a main part that can be rotationally driven about a 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 cutting insert holder is mounted in a guide recess in the main part such that it can be moved transversely, preferably radially, to the rotational axis, and the adjusting device has a control rod that is arranged axially movable inside the main part and supports the cutting insert holder. The cutting tool can be of the multi-point cutting tool type. The invention also relates to a method for machining a bearing tunnel by means of such a multi-point cutting tool.

Abstract: An adjusting device 17 for fine adjustment of a cutting support 14, which is adjustable on a basic body 12 of a cutting tool 10, relative to the basic body 12, with an adjusting screw 63 which determines the position of the cutting support 14 relative to the basic body 12. The adjusting device 17 comprises a threaded bushing 61 with which the set screw 63 is screwed and which has a wall segment 66 which is elastically deformable transversely to the socket axis 70, and a pressure element 64 arranged laterally of the threaded bushing 61 which presses the wall segment 66 against the set screw 63.

Abstract: The invention relates to a roller burnishing tool 10 with a base body 12 extending along a longitudinal center axis 11, at least one roller holder 14 arranged radially adjustably on the base body 12, which holds a roller 15 rotatably, and an adjusting device 16 arranged in the base body 12 for adjusting the roller holder 14 cooperates in the radial direction with the roller holder 14. According to the invention, the roller holder 14 has a holder arm 18b holding the roller 15, which can be pivoted out in a radial direction by the adjusting device 16 relative to the base body 12 in a radial direction.

Abstract: The invention relates to a cutting tool, in particular a rotating machining tool, comprising a support member, a cutting element that is releasably clamped to the support member, and a clamping jaw which is located on the support member, can be secured by means of a clamping screw and clamps the cutting element against the support member. According to the invention, a lifting element is provided between the support member and the clamping claw; when the clamping screw is unscrewed, said lifting element lifts the clamping jaw off the cutting element located on the support member.
