Abstract: A biomimetic desert beetle self-transporting bone microgrinding head and a preparation process thereof, and relates to the field of medical instruments. The microgrinding head includes a hydrophobic matrix or a matrix having a hydrophobic plating layer. The matrix has a hydrophobic surface on which several hydrophilic abrasive particles are uniformly distributed. A process for preparing the microgrinding head is: selecting diamond abrasive particles and conducting oxidization treatment of the diamond abrasive particles; forming a hydrophobic matrix by scanning a surface of the matrix with a laser; or alternatively obtaining a hydrophobic plating layer by a chemical modification method; and combining the oxidized diamond abrasive particles with the hydrophobic matrix or the hydrophobic plating layer by electroplating to obtain a microgrinding head. The microgrinding head utilizes to achieve an effect of being capable of cooling rapidly and capturing cooling medium droplets and effectively transporting the droplets to a grinding arc region.
