| Abstract: | As shear strength of polycrystalline diamond compact bit ,which is made of ordinary braze welding, is not high, a new kind of design thought of using microcontroller to pressurize and control the PCD compound piece in vacuum diffusion bonding is proposed. On the basis of transformation hydraumatic system of original vacuum proliferation welding machine, pressurized circuit controls by microcontroller and program process is designed. The practical application indicates that this technique is economical and practical and yield good economic returns. |
