Diameter or the length of side be 100-500 μm, 600-1000 μm of the grinding pillar height degree, 20-80 μm of the uniformly distributed spacing of the grinding column；
The dimple structure processed using the grinding column in joint ball surface, has good oil storage greasy property, Ultrasonic machining
Texture scale plays a part of carrying.
9. the micro- texture processing unit (plant) of medical joint prosthesis ball surface according to claim 5, it is characterized in that：Medical artificial pass
Section ball is made of Titanium alloy Ti-6Al-4V, passes through different operating mode, different vibration dimensions, various amplitude, frequency and power
High speed rotation component progress ultrasound is ground crowded；Give simultaneously coolant that different types of flow postponed from small to large to chilling into
Row cooling, finally processes the micro- texture in surface on joint ball.
