Abstract
A diamond inner bore grinding wheel comprises a substrate made of No.45 steel. An axial blind hole is arranged in the center of the substrate, a working layer is connected with the outer side of the lower end of the substrate in a pressing mode, an annular groove is arranged in the working layer, a radial through hole is arranged in the groove, and the radial through hole is communicated with the axial blind hole. According to the grinding wheel, the through hole is arranged in the working layer, water can conveniently pass through the through hole, the temperature is conveniently reduced, working efficiency is effectively improved, service life of the grinding wheel is prolonged, production cost is greatly reduced, and working efficiency is improved due to the fact that the groove of the working layer facilitates chip remove.
Description
Technical field
The utility model belongs to the diamond tool technical field, relates in particular to a kind of diamond endoporus emery wheel.
Background technology
The diamond consumption, 1,000,000 tons of iron and steel of every processing diamond amount used 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 every 1,000,000 tons of steel, and U.S.'s diamond consumption in the world is maximum national.Every 1,000,000 tons of steel draw in China 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.
The endoporus emery wheel of existing market, product structure is single, has some setbacks due to chip removal during use or heats up comparatively fast, and cooling effect is bad, causes service life shorter, has greatly affected production cost, has caused unnecessary loss and waste.
The utility model content
Technical problem to be solved in the utility model is to provide a kind ofly to be convenient to lower the temperature and the diamond endoporus emery wheel of chip removal.
In order to address the above problem by the following technical solutions: a kind of diamond endoporus emery wheel, comprise the matrix of being made by No. 45 steel, the matrix center is provided with axial blind hole, the outside, matrix lower end is crimped with working lining, working lining is provided with annular recess, be provided with radial direction through hole in groove, radial direction through hole communicates with axial blind hole.
Described working lining is the diamond abrasive layer.
Described axial blind hole communicates with the matrix upper end.
The utility model arranges through hole at the working lining place, can facilitate water flowing, is convenient to cooling, has effectively improved operating efficiency and emery wheel life-span, greatly reduces production cost.The groove of working lining is convenient to chip removal, increases work efficiency.
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 endoporus emery wheel, comprise the matrix 1 of being made by No. 45 steel, matrix 1 center is provided with the axial blind hole 2 that communicates with the matrix upper end, the outside, matrix lower end is crimped with working lining 3, working lining 3 is provided with annular recess 4, is provided with radial direction through hole 5 in groove 4, and radial direction through hole 5 communicates with axial blind hole 2.Working lining is the diamond abrasive layer.
Claims (3)
1. diamond endoporus emery wheel comprises the matrix of being made by No. 45 steel, it is characterized in that: the matrix center is provided with axial blind hole, the outside, matrix lower end is crimped with working lining, working lining is provided with annular recess, is provided with radial direction through hole in groove, and radial direction through hole communicates with axial blind hole.
2. diamond endoporus emery wheel according to claim 1, it is characterized in that: described working lining is the diamond abrasive layer.
3. diamond endoporus emery wheel according to claim 1 is characterized in that: described axial blind hole communicates with the matrix upper end.
