Embodiment Construction

[0018] The basic configuration of the tool shown in the figures comprises a carrier part 1 and a working part 2 in the form of a support plate. The carrier part 1 has a holder 3 on which a carrier plate 4 made of rubber is sprayed on. The carrier plate 4 has cooling channels 5 extending from the inside to the outside, which are separated from one another by ribs 6 also running from the inside to the outside. At the inner end of the cooling channels, each cooling channel 5 communicates with the atmosphere via air inlet holes 7 on the rear side 8 of the carrier plate 4 . The top side of the rib 6 opposite the rear face 8 defines an abutment surface 9 for the working part 2 . For reference, DE 10 2004 009 443 A shows and describes the design of a carrier plate 4 with cooling channels 5 .

Abstract

The present invention discloses a tool comprising a carrier part (1) and a disc-shaped working part (2) for chip-forming machining. The two parts (1, 2) are detachably connected with each other by means of a coupling part (20) and a counter-coupling part (21) that are inter-locked. The coupling part and the counter-coupling part exhibit convex and concave wall sections (25, 30, 24, 29) adapted to each other. Moreover, there is created a latch-in connection by an inside hexagon aperture (27) and an outside hexagon (31).

Description

technical field [0001] The invention relates to a tool with a carrier part and a working part for chip / chip forming machining. Background technique [0002] Such knives are known in different embodiments, in which each carrier part or base body is connected to a working part, which is a wearing part. Such working parts are, for example, grinding media on a base body, polishing and cleaning discs or felt discs consisting of needle fleece with embedded grinding media. The carrier part and the working part are rotatably driven. In known embodiments, an internally threaded connection part is fitted on the opposite side to the working side, which is screwed into the thread of the carrier part. Often, the attachment and detachment of the working part and the carrier part is cumbersome or time consuming, or requires extreme care to be accomplished. This is annoying because such working parts often have to be replaced after only a short period of use. This is especially the case...
