Abstract
The utility model relates to a kind of grinding disk, described abrasive disc is followed successively by black ply of paper, the first glass layer, function material layer, the second glass layer and label ply of paper from side to opposite side, the middle position of abrasive disc is provided with through hole, be provided with becket in through hole, described function material layer is embedded with layer of metal stratum reticulare.Abrasive disc provided by the utility model, is being embedded with layer of metal stratum reticulare with function material layer, improves the radiating rate that function material layer cuts border preferably, so improve the cutting effect of abrasive disc.
Description
Technical field
The utility model relates to cutting blade field, specifically relates to a kind of grinding disk.
Background technology
In abrasive disc common at present, according to the difference of cut material, the thickness of abrasive disc, structure are all in larger difference.In working angles, the cutting border (outer border) of abrasive disc is with to be cut the portion temperature that material contacts the highest, and cut border and be not in medium with the portion temperature being cut material, the non-cutting border temperature of abrasive disc is lower.In high-speed machining process, abrasive disc cuts cutting tip on border and is in alternating state all the time with cutting border non-cutting part, therefore cuts the circulation that border exists temperature-high temperature in one-middle temperature all the time.
Generally, when cutting border temperature is lower, cutting effect is better, and when temperature is higher, cutting effect is poor.But in the middle of existing commercially available abrasive disc, the cutting border type of cooling of abrasive disc is and relies on the rotation of abrasive disc to carry out natural air cooled, and the actual cut part of abrasive disc mostly is non-thermally conductive material, the poor thermal conductivity of cutting border is to a certain degree limiting the further raising of abrasive disc cutting effect.
Therefore, how designing a kind of novel abrasive disc, is the problem that those skilled in the art's letter need solve.
Utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provides a kind of grinding disk.Abrasive disc provided by the utility model, is provided with metal net layer in function material layer, improves the radiating rate that function material layer cuts border preferably, so improve the cutting effect of abrasive disc.
In order to reach above-mentioned purpose, the utility model adopts following technical scheme:
A kind of grinding disk, described abrasive disc is followed successively by black ply of paper, the first glass layer, function material layer, the second glass layer and label ply of paper from side to opposite side, the middle position of abrasive disc is provided with through hole, be provided with becket in through hole, described function material layer is embedded with layer of metal stratum reticulare.
Preferably, also nonwoven layer is provided with between described second glass layer and label ply of paper.
The beneficial effects of the utility model are: function material layer embedded metal stratum reticulare, the partial heat of the cutting border of function material layer can be transmitted to non-cutting border, thus reduce the temperature of cutting border to a certain extent, improve the heat-conducting effect of cutting border part, finally improve cutting effect.
Accompanying drawing illustrates:
Fig. 1 is cross-section structure of the present utility model;
1, black ply of paper, the 2, first glass layer, 3, function material layer, 4, metal net layer, the 5, second glass layer 6, nonwoven layer, 7, label ply of paper, 8, through hole, 9, becket.
Detailed description of the invention:
Embodiment 1: a kind of grinding disk, its structure is as shown in Figure 1: described abrasive disc is followed successively by black ply of paper 1, first glass layer 2, function material layer 3, second glass layer 5 and label ply of paper 7 from side to opposite side, the middle position of abrasive disc is provided with through hole 8, be provided with becket 9 in through hole 8, described function material layer 3 is embedded with layer of metal stratum reticulare 4.
Nonwoven layer 6 is also provided with between described second glass layer 5 and label ply of paper 7.
Preferably be chosen as, metal net layer 4 is red copper material, and function material layer can select white fused alumina material.
During cutting, synchronous and the function material layer of metal net layer 5 is cut object, the heat that the cutting part of cutting border produces can be passed to the cutting non-cutting of border and the non-cutting border part of abrasive disc in the very first time by metal net layer 5, make the temperature of cutting part can not be too high, and then improve the heat-conducting effect of cutting border part, finally improve cutting effect.
In above-mentioned feature, what do not give explanation is prior art.
By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
Claims (2)
