摘要： A machine tool (1) of high-frequency vibration is provided. A main shaft structure (100) of the machine tool (1) comprises a rotating shaft (120), the end of which is provided with a tool holder chuck (130) for fixing a tool holder (200); the upper portion of which is provided with a rotating coil portion (150); the main shaft structure (100) is correspondingly provided with a stationary coil portion (140); and the tool holder (200) is provided with a high-frequency vibration module (240). By non-contact coils (140, 150), an external electric power/signal can be transmitted into the high-frequency vibration module (240) to avoid a wear phenomenon in a contact-rotating electrode. Because the inductive coil (140, 150) is arranged outside of the tool holder (200), the manufacturing cost of the tool holder (200) is reduced, and the convenience of changing the tool holder (200) is increased. Moreover, the machining stability and efficiency of the tool holder (200) are improved by a control method of sensing/feedback signals with wireless transmission.

摘要翻译： 提供高频振动的机床（1）。 机床（1）的主轴结构（100）包括旋转轴（120），其端部设置有用于固定工具架（200）的工具夹具（130）; 其上部设置有旋转线圈部分（150）; 主轴结构（100）相应地设置有固定线圈部分（140）; 并且所述工具架（200）设置有高频振动模块（240）。 通过非接触线圈（140,150），可以将外部电力/信号传输到高频振动模块（240）中，以避免接触旋转电极中的磨损现象。 由于感应线圈（140,150）布置在工具架（200）的外侧，因此工具架（200）的制造成本降低，并且改变工具架（200）的便利性增加。 此外，通过无线传输的感测/反馈信号的控制方法，提高了刀架（200）的加工稳定性和效率。
