Method for rapidly and nondestructively measuring PCD (Polycrystalline Diamond) deformation

The invention discloses a method for rapidly and nondestructively measuring the PCD (Polycrystalline Diamond) deformation, which comprises the following steps of: 1, grinding the surface of a PCD material by using a grinding machine until a polycrystalline diamond layer is completely exposed; secondly, the polycrystalline diamond layer of the PCD material is placed on flat grinding equipment in an attached mode, and the upper side face of the PCD material is subjected to flat grinding machining through the flat grinding equipment; thirdly, the PCD material is primarily machined through plane grinding equipment, the alloy layer 1 is exposed, and the exposed point serves as a starting point; step 4; the PCD material is machined through flat grinding equipment till the cup wrapping the upper side face of the PCD material is completely removed, and the point serves as an ending point; through the arrangement, the deformation can be rapidly detected on a production line, the device is suitable for deformation dete
