Abstract
The utility model discloses a glue-laminated grinding wheel which is formed by three layers in a composite mode. The three layers of the grinding wheel include a middle glue layer, an upper grinding wheel layer and a lower grinding wheel layer, wherein the middle glue layer is made of polyvinyl butyrate. The glue-laminated grinding wheel has the advantages that due to the adhesion force of the middle glue layer, lateral pressure resistance is improved, even if the grinding wheel breaks, broken pieces are not prone to be splashed and separated, the accident rate that the people are hurt by the broken pieces is greatly reduced, and construction safety is improved.
Description
Technical field
The utility model relates to a kind of grinding wheel, especially relates to a kind of doubling grinding wheel.
Background technology
Grinding wheel is a kind of cutting polishing consumptive material, and it cuts in high speed circumference motion process or the object such as the metal of polishing, and generally can not bear larger lateral pressure, and impact resistance is poor, so cutting blade easily breaks, and sliver splashes and easily hurts sb.'s feelings, and causes construction dangerous.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned problems in the prior art, and a kind of safe and reliable doubling grinding wheel is provided.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
A kind of doubling grinding wheel of the present utility model, it is composited by three layers altogether, i.e. middle film layers and upper and lower emery wheel layer.
Described film layers is ethene polymers butyrate film.
The utlity model has following beneficial effect:
A kind of doubling grinding wheel of the present utility model because the bonding force of intermediate rubber lamella, has improved the ability of lateral pressure resistant power, even grinding wheel breaks, and the sliver disengaging that is difficult for splashing, thus greatly reduce the accident rate that sliver is hurted sb.'s feelings, improved the construction safety degree.
Description of drawings
Fig. 1 is the cutaway view of a kind of embodiment of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
With reference to Fig. 1, a kind of doubling grinding wheel, it is composited by three layers altogether, the film layers 1 in the middle of namely and upper and lower emery wheel layer 2, described film layers 1 is ethene polymers butyrate film, its using method is identical with common grinding wheel.
Claims (2)
1. doubling grinding wheel, it is characterized in that: it is composited by three layers altogether, the film layers in the middle of namely and upper and lower emery wheel layer.
2. a kind of doubling grinding wheel as claimed in claim 1, it is characterized in that: described film layers is ethene polymers butyrate film.
