Definitions
- the present invention cutting, grinding or drilling tools with low height cutting or grinding layers.
- Cut-off tools such as cut-off wheels, drill bits, milling and grinding tools or also ropes equipped with cutting beads which contain hard materials (preferably diamond) are known in a variety of ways from the prior art. In the majority of cases, the cutting elements are manufactured by sintering. Hard materials are only applied galvanically for a few applications.
- the quality of such a tool is determined by three criteria:
- EP-B-0 931 180 discloses a method for coating a cutting disc by melting the covering with a laser beam.
- the cutting surfaces produced in this way basically have the same problem as sintered, i.e. the wear resistance of the bond holding the hard materials must be adapted to the intended use.
- PCT / DE98 / 02947 it is known from PCT / DE98 / 02947 to provide a titanium-containing intermediate layer between the base body and the cutting surface in such a method in order to achieve greater adhesion of the cutting surface.
- the object of the present invention is to provide a cutting, grinding or drilling tool with cutting or grinding layers of low height, which has the ease of cutting of an electroplated tool in the initial phase, but whose cutting surface allows hard material and bond wear and thus good service life values allows, the method for producing such tools should be inexpensive and lead to economical and versatile tools.
- a cutting, grinding or drilling tool with cutting or grinding layers of low height consisting of a driven base body with an abrasive layer containing hard material grains or with segments, teeth or the like provided with an abrasive layer containing hard material grains, characterized in that the layer consists of a non-ferrous metal or a metal alloy, that the layer for receiving the hard material grains on the base body, the segments, teeth or the like is in an at least partially melted state and that the hard material grains are conveyed onto the melt by means of an air or gas conveyor jet and have at least partially penetrated into the melt
- the base body and the segments or teeth are made of non-ferrous metal or the metal alloy
- the layer of non-ferrous metal or a metal alloy is preferably applied to the base body, the segments or teeth in a melting process. brought, wherein the layer is subjected to a cooling and solidification process before applying the hard body.
- the metal alloy is bronze.
- the layer is preferably melted by a laser beam.
- the layer can be melted electrically, such as by means of an induction loop.
- the gas conveyor jet preferably consists of protective gas and the hard material particles preferably consist of diamond.
- the layer is profiled.
- a method for producing a cutting, grinding or drilling tool with cutting or grinding layers of low height, consisting of a driven base body with an abrasive layer containing hard material grains or with segments, teeth or the like provided with an abrasive layer containing hard material grains, is characterized according to the invention by the Steps:
- the base body, the segments or teeth consist of the non-ferrous metal or the metal alloy.
- the layer made of non-ferrous metal or a metal alloy is preferably applied to the base body, the segments or teeth in a melting process, the layer being subjected to a cooling and solidification process before the hard bodies are applied.
- the layer is preferably melted by a laser beam.
- the layer can be melted electrically, such as by means of an induction loop.
- the gas conveyor jet preferably consists of protective gas and the hard material grains preferably consist of diamond.
