“…In general the Low-Temperature Precision Grinding (LPG) belongs to the first group. However, it combines such features of abrasive machining the flat surfaces of hard and brittle materials as high productivity of conventional grinding, but the surface quality of ground specimens may attain the level of lapping process [2,3].…”

“…Available results of studies in this field do not give the necessary technical information needed for efficient machining of anisotropic materials, particularly synthetic monocrystalline sapphire. For endoprostheses sapphire is the most biocompatible material with the human organism, it possesses high resistant to wear and is durable material for manufacture of the heads or caps of endoprosthesis [1,2].…”

The scale of influence of the single crystal sapphire crystallographic plane orientation and grinding conditions on the material removal rate, surface finish and the state of sub-surface layer have been studied under Low-Temperature Precision Grinding (LPG). The schemes of forming partial spherical heads for human hip joints endoprostheses are considered and elaborated. The possible versions of forming the spherical heads of endoprosthesis based on the novelties in kinematics and the mode of material removal are discussed.

In view of the fact that the endo-prosthesis heads of human hip-joint are operated in extreme conditions, in respect of load, the selection of corresponding material and also increase of precision and quality of machining of spherical surfaces is rather topical task. In the submitted work are reviewed the problems connected with definition of the influence degree of orientation of the sapphire crystal on its workability during diamond grinding with a butt of the ring and elaboration of the perspective, original scheme of formation of the incomplete spherical surface, particularly, of the sapphire head of endo-prosthesis of the human hip-joint.
