Patent ID: 11654493

Abstract:
A high frequency vibration spindle system with non-contact power transmission and a method for manufacturing a restraining member used therein are disclosed. The high frequency vibration spindle system comprises: an electric power transmission device including a first induction module and a second induction module, wherein the second induction module is disposed at either a spindle or a toolholder and is adapted to receive an electric power from the first induction module in a non-contact electromagnetic induction manner; a transducer adapted to vibrate the tool and disposed at the toolholder and electrically connected with the second induction module to receive the electric power; and-a restraining member located between the first induction module and the second induction module. With the restraining member, the structural strength and stability of the second induction module can be improved, thereby increasing the maximum rotational speed of the high frequency vibration spindle system.
