UNITA' DI LAVORO PER MACCHINA UTENSILE CON MOTORE ELETTRICO LINEARE DI MOVIMENTO ASSIALE DEL MANDRINO

摘要

The invention concerns the work units for automatic machine tools in which a spindle (5) moves in translation and rotates with respect to a work axis (Z). More particularly in these units, in order to obtain the rotation/translation of the spindle, the latter is housed in a sleeve (3) that slides along the work axis (Z), with respect to which it is however free to turn.
