[0017] Combined with Figure 1-2 :

[0018] A sharp and efficient PCD grinding wheel includes a substrate 1. The substrate 1 includes a central ring 11, a connecting ring 12 and a grinding block ring 13. A plurality of groups of tooth blocks 2 are provided on the grinding block ring 13. The plurality of groups of tooth blocks 2 are arranged equidistantly around the axis of the substrate 1. A plurality of groups of grooves 3 are provided on the substrate 1. The plurality of groups of grooves 3 respectively match the plurality of groups of tooth blocks 2. One end of the groove 3 away from the tooth block 2 penetrates through the substrate 1.

[0019] Further, the groove 3 is inclined, and one end of the groove 3 close to the tooth block 2 is inclined towards the inside of the substrate 1.

[0020] Further, the tooth block 2 is fan-shaped, and the central angle of the tooth block 2 is set towards the middle of the substrate 1.

[0021] Further, the grinding block ring 13 and the central ring 11 are coaxially arranged. The connecting ring 12 is arranged between the grinding block ring 13 and the central ring 11. The connecting ring 12 is inclined towards the side where the tooth block 2 is provided on the grinding block ring 13.

[0022] Further, a plurality of groups of through holes 4 are provided on the connecting ring 12. The plurality of groups of through holes 4 are arranged equidistantly around the axis of the substrate 1.

[0023] Specific application embodiments of the present utility model:

[0024] The tooth block 2 is arranged on the grinding block ring of the base body 1. The slot 3 is connected to the gear. The slot 3 is located on one side of the rotation direction of the base body 1, and one end of the slot 3 penetrates through the base body 1, which is beneficial for the debris generated during the scraping of the tooth block 2 to leave between the base body 1 and the grinding part along the slot 3, avoiding the damage of the tooth block 2 caused by the contact and collision between the debris and the tooth block 2. The depth of the slot 3 at the end adjacent to the tooth block 2 is deeper, and the depth at the end far from the tooth block 2 is shallower, which is beneficial for the debris to move along the slot 3.
