Further setting the following steps: and the plurality of first reinforcing threads and the plurality of second reinforcing threads are mutually connected.

Through adopting above-mentioned technical scheme, the mode of interconnect can be better constitute a whole between a plurality of first enhancement lines and a plurality of second enhancement line, when local atress appears, the effort can be better share to wholly bear to this further promotes the structural strength of reinforcing net piece, promotes abrasive cutoff piece's overall structure intensity.

Further setting the following steps: the abrasive material comprises an abrasive material body, wherein the abrasive material body is provided with reinforcing meshes, the number of the reinforcing meshes is two, the two reinforcing meshes are respectively arranged on two opposite side surfaces of the abrasive material body, the two reinforcing meshes are arranged in parallel, and the reinforcing meshes are arranged in the abrasive material body.

Through adopting above-mentioned technical scheme, the reinforcing net piece that distributes in abrasive material body both sides can form concentrated enhancement to the abrasive material body that is located between them, and the reinforcing net piece that the rethread set up removes the inside structural strength of reinforcing abrasive material body to make the bulk strength of abrasive cutoff piece realize strengthening, reach higher structural strength.

Further setting the following steps: one side surface of the abrasive body is provided with a content paste, the content paste is provided with a turning arrow mark, and the arrow direction of the turning arrow mark is arranged in the same direction as the bending direction of the second reinforcing line.

Through adopting above-mentioned technical scheme, the existence of turning to the arrow point sign plays guide and indicating action to the installation of abrasive disc cutting piece, avoids appearing the installation mistake and influences abrasive disc cutting piece's life.

Further setting the following steps: a plurality of fixing holes are distributed in the steel ring, and a fixing edge embedded in the abrasive body extends from the wall of each fixing hole.

Through adopting above-mentioned technical scheme, the setting up of steel ring increases clamping strength, makes the emery wheel be difficult to appear bursting apart, further promotes the area of contact of steel ring and abrasive material body through the fixed limit that forms to promote the fixed connection intensity between the two of steel ring and abrasive material body.

In conclusion, the utility model has the following beneficial effects: the utility model has higher strength and longer service life.
