[0005] A further object of the present invention is to avoid the problem of loose fixation of the grinding part.

[0006] Another further purpose of the utility model is to improve the stability of the grinding part, and to improve the use effect and strength.

[0007] In particular, the utility model provides a cutting and grinding dual-purpose grinding wheel, comprising a cutting disc, a raised mounting seat is provided in the middle of the cutting disc, and a plurality of mounting holes are provided in the middle of the mounting seat;

[0008] A fixing groove, wherein the fixing groove is arranged on one side of the cutting disc, and the fixing groove is arranged in a circular array with the mounting seat as the center;

[0009] A grinding sheet is arranged on the same side as the fixing groove, and a corresponding protrusion is arranged on the side of the grinding sheet facing the fixing groove.

[0010] Furthermore, a penetrating fixing hole is arranged in the fixing groove, and a corresponding through hole is also arranged on the protrusion of the grinding sheet.

[0011] Furthermore, a plurality of reinforcing ribs are arranged in the cutting disc.

[0012] Furthermore, a plurality of reinforcing ribs are arranged in the cutting disc, and the fixing holes penetrate through the reinforcing ribs.

[0013] Furthermore, the diameter of the grinding sheet is smaller than the diameter of the cutting disc.

[0014] Technical effects and advantages of the utility model:

[0015] The utility model provides a fixing groove on the side of the cutting disk, arranges a protrusion on the side corresponding to the grinding sheet, installs the protrusion in the fixing groove, and sequentially passes the screw through the fixing hole and the through hole, so as to firmly fix the grinding sheet on one side of the cutting disk. The arrangement of multiple protrusions and fixing grooves can increase the contact area between the grinding sheet and the cutting disk as a whole, and prevents the grinding sheet from loosening and falling off in the rotation direction when in use.
