摘要：
The article describes a control system based on the use of a proximity torque sensor with permanent magnets. After giving a block diagram and circuit diagram of the system and describing the operating sequences it shows that the use of this system when drilling holes in the fabric glass laminate of printed circuit boards increases tool life by a factor of 2. 5.
