Tests of high-precision spindles using LHIIS holographic nano-measuring systems
It was studied the radial and axial runout of a spindle using precision nano-holographic measuring systems – linear and angular displacements – length meters and an ultra-precision rotary table. Spindle rotation accuracy was estimated by the value of radial and axial wavering of its front end. The spindle carries out a mechanical rotational movement. During the rotational movement of the spindle, all its points, including the outer surface, describe circles located in parallel planes. The centers of all circles lie on the same line perpendicular to the planes of circles called the axis of rotation. The axis of rotation of the spindle is located inside it. The wavering of the spindle is examined on its upper and lateral surfaces.
