FIELD: machine building.SUBSTANCE: options of the spindle assembly are suggested, it contains a casing, spindle, hydrostatic support, rotation drive and drive of axial spindle oscillation, comprising frequency generator of spindle own longitudinal waves and resonant concentrator of their local amplitude.EFFECT: achievement of the tool axial oscillation with frequency 3-4 kHz and over at amplitude at least 10-20 mcm due to generation of the spindle own longitudinal waves and resonant concentration of their local amplitude at frond end of the spindle.4 cl, 4 dwg |
