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.

Abstract: Provided in the present invention are a dynamic collection device for an oil film and temperature distribution in a grinding zone and an operating method thereof. A spectroscope and a 45-degree flat mirror are utilized to carry out optical imaging of the permeation and infiltration of the grinding fluid in a grinding zone during a grinding process, and a video signal imported into a high-speed camera is converted into a digital signal processed by a CCD photosensitive element, and a dynamic image is imported for dynamic collection. Infrared radiation emitted from the grinding zone is reflected through the 45-degree flat mirror, and transmitted to the thermal imaging camera, and the signal is transmitted to an internal infrared detector. The infrared detector adjusts and amplifies the received signal and outputs it to an infrared thermal imaging chip. After image processing, the temperature distribution image is imported for dynamic collection.
