The invention relates to a machine tool () comprising a clamping holder () which extends along a longitudinal axis () and a cutting element () that can be inserted into an open tool-side recess (), which passes through the clamping holder (), transversely to the longitudinal axis (). The machine tool () has a stop () which is secured in the recess () and against which the cutting element () rests in the direction transverse to the longitudinal axis ().

Machine 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 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.

Cutting tool and method for machining a bearing tunnel

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

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.

Cutting tool comprising a cutting element releasably attached to a support member by means of a clamping jaw

The invention relates to a tool, in particular a revolving tool for machining, in particular metal cutting, workpieces, comprising a carrier body, a cutting body arranged detachably on the carrier body, and a clamping bracket for the positionally accurate fixation of the cutting body relative to the carrier body, wherein the cutting body is pressed against a supporting surface on the carrier body in a planar manner. According to the invention, the clamping bracket is integral with the carrier body and connected to the carrier body by way of a material joint. Furthermore, the cutting body is supported in the direction of the material joint on a face supporting surface of the clamping bracket, wherein the supporting surface is arranged on the carrier body at an acute angle (&#x3b1;) with respect to the face supporting surface of the clamping bracket and oriented in the direction of the material joint.

Tool having detachably clamped cutting body

A machine tool, which is also suitable for high-speed machining in metal cutting, for which at least one cutting body is held by a clamping device in a plate seat of a tool holder, which is bounded only by a back pressure supporting surface and by a supporting surface, the supporting surface for the clamping device and the supporting surface of the plate seat enclosing an angle, which exceeds the automatic interlocking and opens up to the back pressure supporting surface, wherein the cutting body is provided with a groove, which is engaged by a sliding pin, the diameter of which corresponds essentially to the width of the groove and which is disposed eccentrically and parallel to the axis of rotation of the bearing bolt, which is mounted rotatably in a bearing opening of the tool holder, passing through the supporting surface and/or the back pressure supporting surface, and which can be actuated from the outside.
