Embodiment Construction

[0029] figure 1 A perspective view of an embodiment of the invention is shown. The boring tool 1 has a main tool body 2 with an interface 3 to a corresponding drive. Here the interface 3 comprises a steeply-slope conical shaft 3, at the end of which a clamping groove 4 and a flange 5 are provided towards the main tool body 2 for axial support. The interface may also be in the form of a separate component connectable to the main tool body 2 . Here the main tool body has a wheel-shaped portion 6 connected by corresponding spoke portions 7 to an inwardly arranged hub portion. An extension arm 8 is mounted to the main tool body 2 or its spoke portion 7 . The illustrated embodiment has four spoke portions 7 to each of which a respective extension arm is mounted. A cutting blade holder 9 is carried on the extension arm 8, said cutting blade holder 9 having a leg-like protrusion 10 arranged in a slot 11 in the extension arm.

Abstract

The invention relates to a milling or boring tool comprising a base body, said base body being rotatable about a tool axis, and a cutting element, which can be fastened to said base body and has a cutting portion or is intended to receive a cutting insert cutting insert seat. It is an object of the present invention to provide a fastening system for fastening a cutting element to a base body, which can be easily produced at low cost, allows a high-precision positioning of the cutting element on the base body and additionally allows very fast replacement. A centering pin is attached to one part, namely the base body or cutting element, and a corresponding centering opening is provided on the other part, namely the cutting element or base body, said centering pin being arranged parallel to the boring axis, wherein said The axis of the centering pin does not coincide with the tool axis.

Description

technical field [0001] The invention relates to a milling or boring tool having a main tool body which can be rotated about a tool axis and at least one cutting element which can be fastened to the main tool body and have a cutting portion or a cutting insert seat for receiving a cutting insert. [0002] In this aspect, the cutting element may have a multi-part construction, for example comprising an extension arm and a cutting blade holder secured to the extension arm. Background technique [0003] In known tools, the cutting elements are fixed to the main tool body only by screws. However, this requires a relatively high level of positioning error since the exact position of the cutting element on the main tool body depends on the clearance or manufacturing tolerances of the screws used. [0004] In principle, the positioning accuracy can be increased by using screws with a small diameter. However, this has the consequence that the forces that will be carried in many ca...
