Abstract
A device increases the surface smoothness of a turned surface. The device comprising a control system with a control unit and an actuator connectible to the control unit and connectible with a tool holder. The actuator in adapted to impart a vibrating motion in the lateral direction to the tool holder. A method will also increase the surface smoothness of a turned surface, comprising the step of controlling the vibrations of the tool holder during turning. The method also comprises the step of imparting a vibrating motion in the lateral direction to the tool holder. Moreover, a turning lathe and a turning tool holder which like the device are designed to generate vibrating motion in the lateral direction.

A device for increasing surface smoothness of a turned surface, the device comprising a control system comprising a control unit and an actuator connectible to the control unit and connectible with a tool holder, the actuator being adapted to impart a vibrating motion in a lateral direction to the tool holder wherein the tool holder moves in a vibrating manner alternatingly in and against a direction of feed when the device is mounted in a turning lathe, the actuator being spaced from a center, longitudinal axis of the tool holder, wherein the actuator is at least one piezoceramic element which is movable in a direction parallel to the center, longitudinal axis of the tool holder in order to create side-to-side vibration motion in the tool holder.
A turning tool holder comprising an actuator for imparting a vibrating motion in a lateral direction to the turning tool holder, the turning tool holder being moved in a vibrating manner alternatingly in and against a direction of feed when the tool holder is mounted in a turning lathe, the actuator being spaced from the center longitudinal axis of the tool holder, wherein the actuator is at least one piezoceramic element which is movable in a direction parallel to the center, longitudinal axis of the tool holder in order to create side-to-side vibration motion in the tool holder.
A turning lathe comprising a tool holder and an actuator connected with the tool holder, the actuator imparting a vibrating motion in a lateral direction to the tool holder in order to make the tool holder move in a vibrating manner alternatingly in and against a direction of feed, the actuator being spaced from a center, longitudinal axis of the tool holder, wherein the active element is a piezoceramic element which is movable in a direction parallel to the center, longitudinal axis of the tool holder in order to create side-to-side vibration motion in the tool holder.
A method for increasing surface smoothness of a turned surface, comprising the steps of:
- controlling vibrations of a tool holder during turning,
- imparting a vibrating motion in a lateral direction to the tool holder in order to make the tool holder move in a vibrating manner alternatingly in and against a direction of feed, and
- providing an actuator in the tool holder, the actuator being spaced from a center, longitudinal axis of the tool holder and causing the vibrating motion,
- further comprising the steps of using a piezoceramic element as the actuator and moving the actuator in a direction parallel to the center, longitudinal axis of the tool holder.
