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.

Cutting tool comprising an adjusting device

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.

Cutting tool

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.

An adjusting devicefor fine adjustment of a cutting support, which is adjustable on a basic bodyof a cutting tool, relative to the basic body, with an adjusting screwwhich determines the position of the cutting supportrelative to the basic body. The adjusting devicecomprises a threaded bushingwith which the set screwis screwed and which has a wall segmentwhich is elastically deformable transversely to the socket axis, and a pressure elementarranged laterally of the threaded bushingwhich presses the wall segmentagainst the set screw

Adjusting device for a cutting tool and cutting tool having an adjusting device

The invention relates to a roller burnishing toolwith a base bodyextending along a longitudinal center axis, at least one roller holderarranged radially adjustably on the base body, which holds a rollerrotatably, and an adjusting devicearranged in the base bodyfor adjusting the roller holdercooperates in the radial direction with the roller holder. According to the invention, the roller holderhas a holder armholding the roller, which can be pivoted out in a radial direction by the adjusting devicerelative to the base bodyin a radial direction.

Roller burnishing tool

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.
