Description
Technical field
The invention belongs to processing of stone equipment Technology fields more particularly to a kind of stone cutter to have.
Background technology
With developing for processing of stone industry, the demand of the required cutting tool used in processing of stone technical process
Amount also increasingly increase, it is current in the market, provide a variety of cutting tools for cutting stone material.In general, this cutter
Tool also referred to as reason knife, common most of reason cutter have the break bar manufactured by whole hard alloy, it is rolled on glass, is utilized
It is high for 15 myriametres or so, generally 5 to 6 myriametres industrially to cut the glass service life for the cutting edge glass-cutting for having nose angle.But this
The service life of a little reason knives still fails to meet the requirements well.For example, Publication No.:The patent document of " CN202200407U ", it is open
It is a kind of for glass-cutting, the cutting tool of ceramic tile or stone material, which there is plate-like break bar, the plate-like break bar to have
The polycrystalline diamond internal layer of arranged stacked and the double layer of metal outer layer being arranged on polycrystalline diamond internal layer both sides, institute
It states double layer of metal outer layer the polycrystalline diamond internal layer is clamped and fixes between them, the polycrystalline diamond internal layer is along it
It is circumferentially formed with for cutting the glass, ceramic tile or the cutting edge of stone material, wherein the outer diameter of the cutting edge is more than outside the metal
The outer diameter of layer.Using the technical solution of the patent, is introduced in cutter and used polycrystalline diamond material, enable the cutting of cutter
Power greatly improves, still, the cutter when in use, since the cemented carbide material capacity of heat transmission used in cutter outer layer is poor,
Generated cutting heat can not be discharged cutter in time when in use, be easy that cutter is made to burn out, and since cemented carbide material is crisp
Property is larger, and when tool feeding amount is larger, the radial load that cutter is born is larger, exacerbates the abrasion of cutter, and affecting it makes
Use the service life.
