Description
Technical Field
The utility model relates to a grinding sheet especially relates to a grinding sheet and grinder for metallographic test.
Background
At present, when a metallographic test is carried out in colleges and universities or research places in China, when a grinding machine is adopted for grinding, cooling liquid is sprayed to eliminate heat generated during grinding, and in the grinding process, due to the fact that the grinding speed is low, part of the cooling liquid can rotate along with the grinding sheet after flowing into the grinding sheet; the coolant contains ground powder, and the ground powder is filled into the concave holes on the grinding sheet along with the flow of the coolant, which is not beneficial to continuous grinding, so that the treatment of accumulated liquid is suspended from time to time; affecting the duration of the polishing and the polishing rate.
Disclosure of Invention
An object of the utility model is to provide a grinding sheet to prior art not enough, the reducible coolant liquid gathering of this grinding sheet for it is longer to grind the continuation, avoids influencing the grinding speed.
Another object of the utility model is to: a polishing apparatus having the above polishing sheet is provided.
A grinding sheet is provided with concave holes on the surface, protrusions for grinding are formed between adjacent concave holes, and the grinding sheet is provided with a plurality of radial water flowing grooves.
Further, the depth of the launder gradually increases from inside to outside.
Furthermore, the surface of the grinding sheet is also provided with a plurality of annular grooves which are communicated with the water flowing grooves.
Further, each annular groove comprises a plurality of sections of connecting grooves, the connecting grooves are communicated with the adjacent annular grooves, and the depth of each connecting groove is shallow in the middle and deep at two ends.
Furthermore, release paper is bonded on the lower end face of the grinding sheet.
A grinding device comprises a rotating disk, wherein the rotating disk is connected with the grinding sheet.
The utility model has the advantages that: the utility model discloses a set up a plurality of tye and ring channel, can effectually derive the lapping liquid, avoid the gathering to influence the grinding.
Drawings
Fig. 1 is a schematic structural diagram of the present embodiment.
The reference numerals include:
1-grinding plate; 2-a bump; 3-concave hole; 4-a flume; 5-ring groove; 6-connecting groove; 7-release paper.
Detailed Description
The following detailed description of the present invention is made with reference to the accompanying drawings. As shown in fig. 1.
Example 1: a grinding sheet 1 is provided with concave holes 3 on the surface, protrusions 2 for grinding are formed between adjacent concave holes 3, and the grinding sheet 1 is provided with a plurality of radial water flowing grooves 4.
According to the technical scheme, the launder 4 is arranged, so that when the grinding sheet 1 rotates along with the rotary table, accumulated liquid can gradually flow into the launder 4; meanwhile, the accumulated liquid flows outwards along the launder 4 under the centrifugal force, so that the accumulated liquid is prevented from being accumulated on the surface of the grinding sheet 1 and is reduced.
Further, the depth of the launder 4 gradually increases from the inside to the outside.
In order to facilitate the rapid outflow of the polishing slurry from the flume 4, the depth of the flume 4 is gradually increased from the inside to the outside.
Furthermore, the surface of the grinding sheet 1 is also provided with a plurality of annular grooves 5, and the annular grooves 5 are communicated with the water flowing grooves 4.
In practical application, because the distance between adjacent water flowing grooves 4 increases along with the increase of the distance from the axis, in order to avoid the grinding fluid from gathering at a longer distance from the axis, the annular groove 5 is arranged, the annular groove 5 and the water flowing grooves 4 are combined to form a reticular groove, and after the grinding fluid enters the annular groove 5, the grinding fluid flows in the rotating process, gradually flows into the water flowing grooves 4 and is discharged.
Further, each annular groove 5 comprises a plurality of sections of connecting grooves 6, the connecting grooves 6 connect adjacent annular grooves 5, and the depth of each connecting groove 6 is shallow in the middle and deep at two ends.
In order to enable the grinding fluid in the connecting groove 6 to flow into the water flowing groove 4 quickly, the lower bottom surface of the connecting groove 6 is set to be high in the middle and low in two ends.
Further, a release paper 7 is bonded to the lower end surface of the polishing sheet 1.
For the use of convenient abrasive disc 1, this technical scheme is at the lower extreme bonding release paper 7 of abrasive disc 1, when using the installation, directly remove and bond to the rotary disk with release paper 7 can.
A grinding device comprises a rotating disk, wherein the rotating disk is connected with the grinding sheet 1.
The above description is only a preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the present description should not be interpreted as a limitation to the present invention.
Claims (5)
