- and
- a union nut positioned around the output shaft for detachably connecting the output shaft to an attachment end of the tool;
- the output shaft including a locking ring and the union nut including a washer disk and an attenuator, the washer disk being positioned between the locking ring and the attenuator.
A method for operating a machine tool, comprising:
- positioning a union nut around an output shaft of the machine tool for detachably connecting the output shaft to an attachment end of the tool;
- engaging the union nut to the attachment end of the tool until a hard stop is reached between a locking ring of the output shaft and a washer disk of the union nut, wherein the washer disk is positioned between the locking ring and an attenuator of the union nut;
- and
- generating a torque in the machine tool, and transmitting the torque from the output shaft of the machine tool to the tool via the engagement of the union nut to the attachment end of the tool.
