At present, diamond-impregnated wheel is diamond cutter's one kind, can be used for the correct grinding of ceramic tile side, and diamond-impregnated wheel on the market at present adopts overall structure mostly, and the cutting edge nature of the emery wheel diamond working layer of this kind of structure is poor, and to some effects of diamond, needs the grinding of certain precision, need change different radiuses' emery wheel at the in-process of grinding, and the in-process step of change is loaded down with trivial details, and grinding efficiency is low.
When selecting diamond grinding wheels, the use will vary depending on the type of wheel used, for example, when grinding hard ground, soft carcass wheels should be selected; in the case of a relatively soft ground, a relatively hard carcass may be selected. Therefore, when a plurality of materials are needed to be polished, the grinding wheels of different types need to be frequently replaced, the use is inconvenient, and the working efficiency is influenced.
In summary, the problems of the prior art are as follows:
(1) the radius of the traditional grinding wheel needs to be continuously changed in the sanding process, so that the grinding process is complicated.
(2) The grinding wheel of different grade type need frequently be changed when needs are polished to multiple material, and it is inconvenient to use, has influenced work efficiency.
Disclosure of Invention
To the problem that prior art exists, the utility model provides a diamond small grinding wheel.
The utility model discloses a realize like this, a diamond small abrasive wheel is provided with:
a central shaft;
the central shaft is a flat shaft, a plurality of grinding wheels are sleeved on the outer side of the central shaft, and fastening nuts are respectively fixed on two sides of each grinding wheel of the central shaft through threads;
the plurality of grinding wheels have diameters that gradually decrease from a fixed end of the central shaft to an outer end.
The utility model installs the grinding wheels with different radiuses on the same connecting bearing, and can conveniently use the grinding wheels with different radiuses to grind materials in the process of grinding the materials; and the hardness of a plurality of emery wheels can be selected at will and change, conveniently polishes the material of different grade type.
Further, the central hole of the grinding wheel is a flat hole, and the diameter of the flat hole is slightly larger than that of the central shaft.
The utility model discloses a emery wheel passes through flat hole can closely cooperate with the center pin, and realization that can be better rotates in step, rotates asynchronous condition easily when avoiding appearing adopting the round hole and takes place.
Furthermore, external threads are respectively arranged at two ends of the surface of the central shaft, and multiple sections of spaced external threads are arranged on the middle surface of the central shaft.
The utility model discloses an external screw thread at both ends can conveniently carry out fixed connection with center pin and external drive device, need not distinguish the positive and negative end, carries out the interval setting through the multistage external screw thread that will go on fixing to the emery wheel moreover, can be convenient for to the position location of emery wheel, avoids the influence to use by near.
Furthermore, a plurality of friction grains are formed on the outer end face of the grinding wheel and are distributed at equal intervals.
The utility model discloses a plurality of friction lines that the equidistance distributes can improve the effect of polishing to the material, improve the efficiency of polishing.

Detailed Description
In order to further understand the contents, features and effects of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings.
The structure of the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1 to 3, the diamond small grinding wheel provided by the embodiment of the present invention includes: external screw thread 1, center pin 2, emery wheel 3, friction line 4, fastening nut 5.
Example 1:
the central shaft 2 is a flat shaft, a plurality of grinding wheels 3 are sleeved outside the central shaft 2, and fastening nuts 5 are respectively fixed on two sides of each grinding wheel of the central shaft 2 through threads; the diameter of the plurality of grinding wheels 3 is gradually reduced from the fixed end of the central shaft 2 to the outer end.
The embodiment of the utility model installs the grinding wheels 3 with different radiuses on the same connecting bearing, and can conveniently use the grinding wheels with different radiuses to grind materials in the process of grinding the materials; and the hardness of a plurality of emery wheels can be selected at will and change, conveniently polishes the material of different grade type.
Example 2:
the central hole of the grinding wheel is a flat hole, and the diameter of the flat hole is slightly larger than that of the central shaft.
The utility model discloses the emery wheel passes through flat hole can closely cooperate with the center pin, and realization that can be better rotates in step, rotates asynchronous condition easily when avoiding appearing adopting the round hole and takes place.
Example 3:
The embodiment of the utility model provides a can conveniently carry out fixed connection with center pin and external drive device through the external screw thread 1 at both ends, need not distinguish the positive and negative end, carries out the interval setting through the multistage external screw thread that will go on fixing to the emery wheel moreover, can be convenient for to the position location of emery wheel, avoid the influence to use by near.
