PURPOSE:To have accurate sensing and display of the swinging amount of a spindle and rotary processing element by simple actions, by installing a variation sensing and display device at the frame of a machine tool, and by equipping the machine tool itself with self-diagnosis function for vibrations. CONSTITUTION:A vibration sensing and display device 12 is installed at the frame of a machine tool. This device 12 is composed of a vibration sensing part 7 to sense vibrations of a spindle 3 and a rotary processing element 4, a CPU 24 including a swing amount calculating part 24a to calculate the swinging amount of said spindle 3 and processing element 4 on the basis of the vibration detected, and a swing amount display part 16 to display the calculation of swing amount. here the swing amount calculating part 24a calculates the swinging amount of the spindle 3 and the processing element 4 on the basis of the vibrating detected by said vibration sensing part 7, and the result is indicated on the display 16. The operator watches indications from the display 16, and a weight is affixed to the indexed points in spindle 3 or grinding wheel 4 where generation of max. swinging was registered to provide well balanced revolutions. |
