Abstract

The utility model belongs to a sand disc, particularly a sand disc with slots. The abrasive surface of the sand disc is provided with various geometric figures which are pressed. The utility model is characterized in that the abrasive surface of the sand disc is provided with slots which form various geometric shapes; the inner slot surface of each slot is an abrasive surface with adhesive and abrasive fillers. The utility model which has the advantages of high milling efficiency and long effective service life can replace a plane sand disc without slots for use.

Description

Grooving sand disc

The utility model belongs to a kind of emery disc, relates in particular to a kind of various geometric Grooving sand disc that is pressed out that is shaped on the emery disc flour milling.

The emery disc that generally uses in the present society, be to make matrix with the cotton fiber hard board, with synthetic resin is adhesive, abrasive material is bonded on the matrix forms, flour milling is smooth annular, but this emery disc is owing to slit between the abrasive material is very little, in grinding process, fracture sand formation cuttings on the emery disc and the grindstone dust on the workpiece easily stop up and stick on the emery disc surface, reduced the flour milling sharpness, and then because of intense attrition, make that emery disc surface temperature and workpiece surface temperature are acute to be risen, the surface of the work and shorten emery disc service life of very easily burning.

The purpose of this utility model is to overcome deficiency of the prior art and proposes a kind of Grooving sand disc that can obviously improve grinding efficiency, prolong the flour milling Acceptable life.

The purpose of this utility model is achieved in that by matrix and flour milling forms emery disc, it is characterized in that on the flour milling of emery disc, being shaped on have chip removal, the groove of the various geometric shape figures of thermolysis, rooved face is the flour milling that has binding agent and abrasive material in its groove.

The utlity model has grinding efficiency height, the long advantage of Acceptable life, owing to be shaped on the groove of band adhesive tape sand on flour milling, formed the interrupted grinding face, thereby grinding efficiency is obviously improved, its service life and efficient all are better than existing plain edition emery disc.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a sectional structure chart of the present utility model.

Fig. 3 is the structural representation of difformity groove of the present utility model.

Fig. 4 is the structural representation of difformity groove of the present utility model.

Shown in Fig. 1,2,3,4, the utility model is made up of matrix 3 and flour milling 2, it is characterized in that on the flour milling of emery disc, being shaped on have chip removal, the groove 1 of the various geometric shape figures of thermolysis, rooved face has araldite and abrasive material in its groove.

The utility model is bonded in abrasive material on the matrix 3 with synthetic resin (glue), forms flour milling 2, suppresses various geometric grooves 1 with mould on forcing press on flour milling 2, has synthetic resin (glue) adhesive and abrasive material on the rooved face in this groove.During use, emery disc rotates at a high speed, the grindstone dust and the sand formation cuttings (abrasive material) that produce in the grinding of flour milling 2 and workpiece, because the instantaneous disconnected mill concussion of groove, constantly break away from flour milling 2, and flown to survey discharge, taken away the part grinding heat simultaneously by centrifugal force, be unlikely the obstruction flour milling, the cooling vortex wind that the groove of various geometries of while produces in rotary course has also reduced the surface temperature of flour milling 2 and processing work.Owing to also have abrasive material in the groove, have the later stage ablation equally, grinding efficiency is obviously improved, the result shows after tested, service life and efficient can reach 1-2 times of the plane emery disc of not slotting.The groove of various geometric shape figures of the present utility model can be made as a kind of latticed form, groove is connected mutually and along cutting direction to external radiation.

Claims

1, a kind of Grooving sand disc is made up of matrix (3) and flour milling (2), it is characterized in that: on the flour milling of emery disc, be shaped on have chip removal, the groove of the various geometric shape figures of thermolysis (1), rooved face is the flour milling that has binding agent and abrasive material in its groove.
