[0014] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples. The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.
[0015] This embodiment provides a processing technology for a PCD drill bit with an integral head, which includes the following steps:
[0016] Step 1: Use silver welding and hard alloy shank to weld the purchased PCD base material to obtain the required base material;
[0017] Step 2: Grind the hard alloy part of the base material welded in step 1 with a diamond grinding wheel. After grinding, use a copper wheel to groov the head of the PCD base material, and then use a copper wheel to perform the grooved part Grinding electrolysis;
[0018] Step 3: Use the outer circle of the grinding wheel to electrolyze the PCD base material head, and then continue to use the outer circle of ...
