Embodiment Construction

[0034]A cutting wheel 1 for a cutting machine shown in FIG. 1 has a main piece 2 on the periphery of which sintered blades 3a are sintered. First, diamond powder and binder powder are fed to the powder feeder, which are mixed with one another in a predetermined ratio adapted to the specifications of the cut-off grinding wheel 1 . The binder powder has metal particles. The sintering mixture 4a is applied to the periphery of the cut-off wheel 1, where it is cold pre-pressed into a mushroom shape. Then the mushrooms are baked. By baking, the surfaces of the metal particles are melted and bonded to each other. The resulting metallic structure, ie, the sintered bond, is porous.

[0035] Figure 2 shows the loose bonding of diamond particles 6 in a sintered binder 5a. The sintered binder 5a does not surround the diamond particles 6 very well. In particular, depressions 7 are formed on the contact surfaces of the diamond particles 6 and the sintered bond 5 a, which reduce the siz...

Abstract

The invention relates to a saw blade for a chain saw, in particular a saw blade for a concrete chain saw, which has a plurality of tooth portions (12, 14) with at least one blade seat (14) and at least one blade (3b). The blade has diamond particles embedded in a binder in which the diamond particles are melted.

Description

technical field [0001] The invention relates to a saw blade of a chainsaw, in particular a concrete chainsaw, having a plurality of teeth with at least one blade seat and at least one blade with a hard grains of material. [0002] The invention also relates to a method for producing a saw blade for a chain saw with a plurality of teeth having at least one blade seat and at least one blade. Background technique [0003] Chainsaw blades and methods for their manufacture are known in the prior art. For example, DE 19952979 A1 shows a saw blade for a concrete chainsaw. Unlike cutting wood, which is mainly removed in the form of chips, when cutting concrete the fine particles are removed by grinding in the form of fine dust. Grinding is carried out on the working face of the insert with diamond particles embedded in a binder. [0004] To manufacture saw blades for chainsaws, the blades are coated on a steel substrate in a sintering process. In this case, a mixture of diamond...
