Embodiment Construction

[0042] figure 1 A partial scope of the cutting tool according to the invention in the form of a saw blade 1 is described in detail. The substantially circular saw blade 1 comprises a base body 2 formed from a substantially flat, circular flat material. A high-strength steel is preferably used as flat material, a cutting seat having two faces 61 , 62 and a free zone 64 being laser engraved. This free area 64 is provided so that the surfaces 61 , 62 can be reworked by grinding.

[0043] Furthermore, the base body 2 has shaped clamping elements 3 which, like the cutting insert holders, are engraved on the base body 2 with a laser. Viewed from the center of the base body 2 , the clamping part 3 has an arm 32 that first narrows and then widens in the radial direction, on which the nose part 31 is molded at an angle of approximately 80° to 135°. At its end towards the central extent of the base body 2 , the arm 32 is surrounded by two free spaces 33 , 34 which, together with the ...

Abstract

The invention relates to a cutting tool of a cutter knife fixed in a detachable way, wherein the cutting tool, e.g. a saw blade (1) has a basal body (2) at least with a cutting knife bed fixed with a cutting knife (7). According to the scheme of the invention, the basal body (2) at least has a clamping piece (3) in elastic deformation, and the clamping piece (3) leans against the cutting knife (7) by means of a locating piece (5) in the open of the basal body (2), causing the cutting knife (7) fixed in the cutting knife bed.

Description

technical field [0001] The invention relates to a cutting tool having a basic body with at least a cutting seat in which a cutting blade is fastened. Background technique [0002] In cutting tools of this type, the cutting blade is on the one hand fastened as firmly as possible in the cutter holder in order to prevent the cutting blade from falling out during use. On the other hand, especially in cutting tools with a plurality of cutting seats and correspondingly equipped with a plurality of cutting knives, it is desirable that the cutting knives are mounted in a detachable manner, so that individual cutting knives can be replaced as soon as these are worn out. [0003] The cutting blade can generally be mounted in different ways on the base body of the cutting tool, as exemplified below for a saw blade. [0004] For example, in a saw blade composed of cutting seat seats distributed around a base body in which cutting knives cut the workpiece to be machined as the saw blade...
