Abstract
A diamond thin wall drill comprises a thin wall drill base body, wherein the front end of the thin wall drill base body is provided with a work layer. The diamond thin wall drill is produced in a pressing connection method, the structure is strong in integrity, production cost is low, and using durability is strong.
Description
Technical field
The utility model belongs to the diamond tool technical field, especially designs a kind of diamond thin-wall drill bit.
Background technology
The diamond consumption, the used diamond amount of 1,000,000 tons of iron and steel of every processing represents this national Industry Development Level, and America and Japan and main western countries consumption have all surpassed the 18-20 myriagram and have drawn per 1,000,000 tons of steel, and the U.S. is the maximum country of diamond consumption in the world.Per 1,000,000 tons of steel draw in China then 2.4 myriagrams, and this gap is apparent.
In development diamond grinding tool and cubic boron nitride superhard abrasive material while, these two kinds of superhard abrasive material grinding tools also obtain corresponding development, and the diamond grinding tool is developing faster.Up till now, the diamond grinding tool develops into comparatively complete, a ripe and processing technique field of establishing one's own system.Diamond grinding tool goods such as electroplated diamond inner circle cast-cutting saw slice, needle file, bistrique, man-made diamond circular saw blade, framework saw blade, diamond finishing pen, the stone material diamond abrasive tool, the diamond cylinder grinding wheel, processing iron oxygen uses diamond abrasive tool.
Engineering thin wall drilling bit claims again water drill bit, hollow boring bit, is mainly used in the building, water, electricity, warm, coal gas, air-conditioning, beats porthole when pipeline is installed.Boring, the jacking of the foundation engineerings such as highway, airfield runway, bridge, tunnel, get core.The nonmetal fragile material of answering such as stone material, pottery punches.
The utility model content
Technical problem to be solved in the utility model is diamond abrasive to be combined with thin drilling bit provide a kind of diamond thin-wall drill bit.
In order to address the above problem by the following technical solutions: a kind of diamond thin-wall drill bit, comprise the thin drilling bit matrix, the front end of thin drilling bit matrix is provided with working lining.
The wall thickness of thin drilling bit matrix front end is 0.85mm.
Be connected by crimping between working lining and the thin drilling bit matrix.
The utility model is produced diamond thin-wall drill bit by the crimping form, and structural integrity is strong, and production cost reduces, and useful life longevity is strong.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of diamond thin-wall drill bit comprises thin drilling bit matrix 1, and the wall thickness of thin drilling bit matrix front end is 0.85mm; The front end of thin drilling bit matrix 1 is crimped with working lining 2.Described working lining is diamond abrasive.
Claims (3)
1. diamond thin-wall drill bit, it is characterized in that: comprise the thin drilling bit matrix, the front end of thin drilling bit matrix is provided with working lining.
2. diamond thin-wall drill bit according to claim 1, it is characterized in that: the wall thickness of thin drilling bit matrix front end is 0.85mm.
3. diamond thin-wall drill bit according to claim 1 is characterized in that: be connected by crimping between working lining and the thin drilling bit matrix.
