Abstract

The utility model relates to a diamond end grinding chip, which is composed of a basal body and an annular grinding chip, wherein, the edge of the basal body is in a tooth shape, and small holes are uniformly distributed on the edge of the basal body. The annular grinding chip is pressed in the small holes, is fixed on the edge of one side of the basal body, and is drilled into the small holes, so the end face of the grinding chip is guaranteed to be flat with the end face of the iron basal body (the radius of the end face of the grinding chip is equal to the radius of the end face of the iron basal body). The utility model has the advantages of high grinding efficiency, long service life, less mouth disintegrating phenomenon and easy manufacture.

Description

Diamond end grinding chip

The utility model is a kind of diamond cross grinding sheet, belongs to a kind of grinding tool.

Domestic and international abrasive sheet commonly used generally is that matrix border is made being crimped on this jagged matrix border abrasive sheet after the zigzag; The end face of abrasive sheet exceeds the matrix border end face simultaneously; The problem that it causes is: the efficient of grinding is not high, utilizes the zigzag of matrix border that matrix and abrasive sheet are fixed, and it is fixing not firm, and the phenomenon that occurs destroying abrasive sheet especially easily causes abrasive sheet to scrap like this.

The purpose of this utility model is to invent a kind of diamond cross grinding sheet, overcomes the existing in prior technology problem.

The utility model is to constitute like this: it is made up of matrix 1 and ring-type abrasive sheet 2, the edge of matrix 1 is dentation, the uniform extruding aperture 3 in the edge of matrix 1, ring-type abrasive sheet 2 are fixed on the lateral edges of matrix 1, the dentation end face at the end face of ring-type abrasive sheet 2 and matrix 1 edge.

Accompanying drawing 1 is a front view of the present utility model.

Embodiment of the present utility model: at a diameter is that evenly to get out diameter be 4 millimeters 40 of apertures the edge of 11 centimetres iron-based body, and a side of aperture is done reaming slightly; The abrasive sheet that diamond abrasive and copper layer are combined into is pressed together on the iron-based body along the toothed edge of iron-based body, and the copper layer is pierced in the aperture, guarantees the dentation end face (being that the two radius is identical) at the end face and the iron-based body edge of abrasive sheet.

Compared with prior art, grinding efficiency height of the present utility model, long service life is not easy to produce " chipping " phenomenon, and it is simple, good in economic efficiency that product itself is made processing.

Claims

1, a kind of diamond cross grinding sheet, it is made up of matrix 1 and ring-type abrasive sheet 2, the edge of matrix 1 is dentation, it is characterized in that: the uniform extruding aperture 3 in the edge of matrix 1, ring-type abrasive sheet 2 is fixed on the lateral edges of matrix 1, the dentation end face at the end face of ring-type abrasive sheet 2 and matrix 1 edge.
