Description
Technical field
The utility model relates to grinding technology field more particularly to a kind of emery wheels and grinding device.
Background technique
In glass production process, sanding and polishing is often carried out using edge of the attrition process to glass, to subtract
It is few because cut split caused by face crack, while be passivated glass edge, achieve the purpose that reinforcing glass intensity.
Attrition process is the emery wheel contact glass surface using high-speed rotation, the ground effect pair generated with high speed rotation
Glass edge is polished.Emery wheel usually is respectively provided in glass two sides to be ground glass both sides, keeps high speed to revolve in emery wheel
While turning, Transport Desk carries glass and moves through emery wheel along the direction for being parallel to emery wheel rotation center, connects glass with emery wheel
The treating selvedge grinding of glass is completed in touching.
Existing emery wheel is usually cylindrical wheel, and Fig. 1 is that emery wheel 100 shows 200 grinding of glass in the prior art

In, the non-milled portion of glass 200 is contacted with 100 end face of emery wheel first, so that extruding force effect is generated to glass 200, it should
Extruding force be easy to cause 200 edge crumbling of glass to expand and generate hallrcuts；And glass 200 contacts not with 100 end face of emery wheel
Milled portion is torn excision under the squeezing action of 100 end face of emery wheel and the centripetal force effect of glass 200 and is formed coarse
Excision face, abrasive grains 110 of the excision face after 100 abradant surface of emery wheel in surface to be polished grind smooth.But due to emery wheel 100
Axial dimension it is limited, emery wheel 100 is likely difficult to obtain excision face to the rapid stock-removal of glass 200 in high-speed rotation process
Reasonable smooth degree, to influence the quality of glass 200, and 100 end face of emery wheel is also easy the extruding force effect of glass 200
It causes 200 edge crumbling of glass to expand and generate hallrcuts, influences 200 intensity of glass, reduce by 200 quality of glass.And when default
When stock removal is bigger, excision face is more coarse, and extruding force effect is also bigger, and emery wheel 100 also gets over the grinding effect of glass 200
Difference, 200 quality of glass after processing are difficult to be effectively ensured.

Fig. 2 is the structural schematic diagram for the emery wheel that the utility model embodiment one provides, and Fig. 3 is the utility model embodiment one
The left view of the emery wheel of offer present embodiments provides a kind of emery wheel as shown in Figures 2 and 3, for hard crisp to glass, silicon wafer etc.
Property material substrate 20 carry out grinding.Emery wheel is divided into Primary layer 3, bonding coat 2 and grinding layer 1 from inside to outside radially.It grinds
Mill layer 1 is made of abrasive grains 10 and filler, and abrasive grains 10 protrude the abradant surface that filler is formed, and is ground to substrate 20
Mill processing.Grinding layer 1 is bonded in the outside of Primary layer 3, the i.e. appearance of the inner surface of bonding coat 2 and Primary layer 3 by bonding coat 2
Face fits closely, and the outer surface of bonding coat 2 is tightly bonded with the inner surface of Primary layer 3.It offers on Primary layer 3 through two side ends
The central shaft hole 5 in face, for installing emery wheel to rotation axis.Circular mounting groove is offered on one side end face of Primary layer 3
6, mounting groove 6 and central shaft hole 5 are coaxially disposed, and mounting groove 6 is evenly arranged with multiple mounting holes 4 along its circumferential direction, for passing through end
The components such as lid will be on emery wheel axial limiting to rotation axis.Multiple counterweights are provided between 2 inside of outside and bonding coat of mounting groove 6

Matter.
Further, the granularity of the abrasive grains 10 on the first grinding circumferential surface is less than the abrasive grains on the second grinding circumferential surface
10 granularity roughly ground for the first grinding week quickly in face of substrate 20, and the second grinding week carried out fine fine grinding in face of substrate 20,
The overall process of balance and stabilized baseplate 20 corase grinding and fine grinding, further increases emery wheel to the grinding quality of substrate 20.
In the present embodiment, 10 density of abrasive grains on emery wheel abradant surface is gradually equal along the direction of transition part 9 to ontology 8
Even increase, to keep 10 density of abrasive grains on the second grinding circumferential surface close less than the abrasive grains 10 on the first grinding circumferential surface
Degree, and 10 granularity of abrasive grains on emery wheel abradant surface gradually uniformly increases along 20 direction of feed of substrate, makes the corase grinding of substrate 20
With the gradually transition of fine grinding process, the stationarity that emery wheel grinds substrate 20, adaptively, the grinding on emery wheel abradant surface are improved
