The paper describes the device and operating principle of a high-precision positioning drive based on a magnetorheological (MR) elastomer for micro-drilling blind holes in multilayer printed circuit boards. The results of experimental studies of a drive with a closed control system for step-by-step movement are presented. The operation of the drive in the mode of active vibration isolation is shown and the coefficient of transmission of the vibration displacement amplitude is determined.
