Positioning of a spindle with micrometric forwarding control and tilting of its rotation axis

A positioning of a spindle with micrometric forwarding control and tilting of its rotation axis, comprising a spindle shaft (11) rotatingly supported inside at least a pair of rotatable supports, wherein the at least pair of rotatable supports consists of two spherical elements (13,14) provided with respective housings (12), eccentric with respect to the axis (99), joining the centres of the samespheres, wherein the at least two spherical elements (13,14) are in turn positioned in a cylindrical housing composed of at least two parts (17,17'; 19, 20), two rotation means (23,24), connected to the two spherical elements (13,14) being envisaged, for determining their independent rotation. 利用主轴旋转轴线的测微前进控制和倾斜的主轴的定位，包括旋转地支撑在至少对可旋转支撑件内的主轴(11)，其中至少对可旋转支撑件由两个球形元件(13，14)构成，两个球形元件设置有相对于所述轴线(99)偏心的相应壳体(12)，连接相同球体的中心，其中所述至少两个球形元件(13,14)又位于由至少两个部分(17,17'；19,20)构成的圆筒形壳体中，设想连接到两个球形元件(13,14)的两个旋转装置(23,24)，用于确定它们的独立旋转。
