A hybrid cutting apparatus and a method of cutting a groove are provided. The hybrid cutting apparatus includes: a main body that is connected with a rotation shaft of a machine tool; a grooving tool that is coupled to one side of the main body and for forming a groove at an interior circumference of a workpiece; and a tool position control means that controls a position of the grooving tool to correspond to a cutting surface position of the workpiece.

A roughening tool for roughening a metallic surface of an inner wall of a pre-drilled workpiece bore is disclosed. The roughening tool has a profiled contour provided between the tool clamping shaft and the tool tip. With this contour, a roughened structure can be produced through rotation of the tool by processing the metallic surface in a material removing or non-material removing manner The roughening tool includes at least one profiled web which extends along the tool axis, protrudes from a main tool part, and on whose outer web back the profiled contour is provided.

Disclosed is a device for removing tool joint edge burrs from a cap opening of a wheel. Four positioning rods circumferentially form a cone, and angle adjusting cylinders drive sliding blocks to move up and down. An electric cylinder drives an adjusting cone to move up and down to adjust the distance between a left cutting edge and a right cutting edge, and by adjusting the distance between the cutting edges, a cutter system is prevented from interfering with a narrow cap opening during descending, and an L-shaped revere chamfer cutter can be formed. According to the invention, not only is the space saved, but also the working efficiency is improved. The device can automatically remove burrs from a first and second tool joint inside a cap opening, can be used for automatic continuous production, and is advanced, stable, efficient and high in accuracy.

A boring head (1) with an electronic unit (20) integrated in the boring head (1) is provided, the electronic unit (20) comprising a control unit (60), a display (30) and a compartment (26) for a power source (41). The display (30) is connected to the control unit (60) and serves to display information concerning the status of the boring head (1) to a user. The compartment (26) serves to accommodate a power source (41) to supply the control unit (60) and the display (30) with electric power. The electronic unit (20) as a whole is designed as a compact subassembly of the boring head (1).

A cutting tool includes a main body suitable to be mounted pivotably about an axis of rotation. A cutting head is carried by a carrying member. The carrying member is mounted displaceably in translation on the main body along an axis perpendicular to the axis of rotation. A counterweight is displaceably mounted in translation on the main body along an axis perpendicular to the axis of rotation. The cutting tool also includes an adjusting spindle for the simultaneous adjustment of the carrying member with respect to the counterweight, arranged on either side of the axis of rotation of the main body.

A modular boring head includes a tubular main body having an internal thread with a first pitch and a pair of axially extending cantilevered members. A movable rod engages the tubular main body such that the movable rod is movable with respect to the tubular main body in an axial direction, D. The movable rod has an internal thread with a second pitch different than the first pitch. A leadscrew is disposed within the tubular main body and has a plurality of gear teeth. Rotation of the leadscrew causes the pair of axially extending cantilevered members of the tubular main body to cooperatively engage with the plurality of gear teeth of the leadscrew in such a manner so as to produce an audible and tactile click, each click being indicative of a distance the movable rod is displaced with respect to the tubular main body.

A boring tool includes a tool body rotatable around a central rotation axis. A slider member is arranged movably inside the tool body along a path extending transversely to the rotation axis. An insert pocket is associated with the slider member to move therewith and configured to receive a cutting insert with a cutting edge and which projects from the tool body transversely to the rotation axis. A motor member is connected to the slider member and controllable to move the slider member transversely to the rotation axis for changing the distance of the cutting edge to the rotation axis. The motor member is arranged inside the tool body together with the slider member in a cutting part of the tool body at a front end thereof. The motor member is arranged in parallel with the transversal extension of the slider member along said path.

A cutting tool includes a cutting chip and a chip holder. The chip holder includes: a body part having a height dimension larger than a width dimension, the body part including a first attachment face that intersects with a cutting feed direction, and a second attachment face that intersects with the first attachment face; a chip support part whose base end portion is connected to the body part and in which the cutting chip is attached to the upper end portion in the height direction of a tip end portion of the chip support part such that the cutting chip projects to one side in the width direction of the chip support part; a reinforcement part provided along the height direction of the chip support part; and a chip receiving part that supports the cutting chip projecting from the chip support part.

An apparatus that includes a tool head; an insert that is coupled to the head and configured to engage an inner diameter of a workpiece, so as to machine the workpiece; a boring bar or drill tube coupled to the head, the boring bar or drill tube configured to extend through a guide bore in the workpiece; and a measuring device that is positioned proximate to the head and configured to measure a radial dimension, an axial dimension, or both of the inner diameter. The head may include a plurality of inserts, wherein the plurality of inserts are selectable such that the inserts are engageable with the inner diameter of the workpiece. The measuring device may include a contact-based measuring device.
