| 摘要 |
The present invention provides an axial machining device comprising a tool-carrier spindle rotatable in a housing, the housing housing a transmission system causing the spindle to advance automatically relative to the housing under the effect of the tool-carrier spindle being driven in rotation, the transmission system including an advance gearwheel screwed onto the spindle, the device including a resilient return member urging the advance gearwheel in a first axial direction opposite to the advance direction of the spindle, and also including a first rolling bearing having rolling members rolling on an undulating raceway having an axial component, thereby periodically urging the advance gearwheel to move in a second direction opposite to the first, such that rotation of the spindle is accompanied by axial vibratory motion. |
