The utility model provides a technical scheme that above-mentioned problem adopted does: the utility model provides a processing diamond grinding wheel for cast iron, it includes the metal substrate, the metal substrate periphery is provided with abrasive ring and lower abrasive ring, it all is connected with the metal substrate through the screw thread to go up abrasive ring and lower abrasive ring.

Optionally, an external thread is arranged on the outer wall of the metal matrix, internal threads are arranged on the inner walls of the upper grinding ring and the lower grinding ring, and the external thread is matched with the internal threads.

Optionally, the metal substrate is made of an aluminum material.

Optionally, metal matrix outer wall upside is provided with the round bulge loop, it is provided with the round recess to go up abrasive ring inner wall upside, bulge loop and recess looks block.

Optionally, a plurality of bolt holes are formed in the threaded connection position of the lower abrasive ring and the metal base, the bolt holes extend upwards to the position of the upper abrasive ring, and connecting bolts are arranged in the bolt holes.

Optionally, go up the abrasive ring and all include two-layer structure inside and outside with lower abrasive ring, wherein the inlayer is the transition layer, and the skin is the diamond layer.

Optionally, the transition layer is made of copper.

Optionally, the transition layer and the diamond layer are both formed by powder.

Compared with the prior art, the utility model has the advantages of:

1. the inner layer of the abrasive ring is a copper base layer, the outer layer is a diamond layer, the metal base body is connected with the copper base layer through threads, the copper base layer and the diamond layer are both formed by powder, and the adjacent layers are tightly combined, so that the ring-off phenomenon is not easy to cause;

2. the utility model adopts the upper and lower abrasive rings, thereby reducing the heat productivity of the grinding wheel, being not easy to damage and prolonging the service life;
