Research on Functional Surface Grinding of Medical Titanium Plate

Medical titanium plates with smooth surface will be long-standing in body under the condition of free state when it used for bone fixation. To solve this problem, function-surface titanium plates with a certain roughness and shape must be grinded. So ceramic CBN abrasion wheel is used to grind titanium alloy in CNC machining tool and the status of force, heat and vibration in the grinding process will be monitored in the same time. The surface morphology which can meet the growth of tissue could be obtained in a certain technological conditions by observing the grinded surface with super depth of field microscopy devices.
