Abstract

Un apparecchio (10; 80) di foratura con base portapezzo elettromagnetica, dotato di un trapano elettrico puntato verso il basso, è provvisto di una base elettromagnetica (64) avente un elettromagnete (24) per l'attacco dell'apparecchio (10; 80) ad un oggetto (76) da lavorare per forza magnetica. Il trapano elettrico è messo in rotazione da un motore (20) della punta e spostato da un motore (26) di avanzamento verso l'oggetto (76). Un elemento Hall (62) si colloca sulla base elettromagnetica (64). Due comparatori (72, 74) rivelano se una tensione Hall in uscita dall'elemento Hall (62) rientri o meno in un intervallo prefissato di valori di tensione. Quando la tensione Hall non cade entro questo intervallo, viene acceso un transistore (58). Conseguentemente, viene messo in funzione un relè (30), viene aperto un contatto (28) e viene interrotta l'alimentazione di energia al motore (20) della punta ed al motore (26) di avanzamento.
