ULTRASONIC DRILLING MACHINE METHOD FOR OPERATING AN ULTRASONIC DRILLING MACHINE, AND ULTRASONIC DRILLING MACHINE

摘要

The invention relates to a method for operating an ultrasonic drilling machine, in particular a handheld ultrasonic drilling machine (100), for the material-removal machining of a workpiece (166), in particular a substantially mineral workpiece (166), by means of an insert tool (160) rotationally driven by a drive unit (130) of the ultrasonic drilling machine (100), wherein a longitudinal ultrasonic oscillation (110) produced by means of an oscillation actuator (105) of the drive unit (130) can be superposed on a rotational motion of the insert tool (160), the ultrasonic oscillation (110) is modulated by means of a control device (200) of the ultrasonic drilling machine (100).
