The invention relates to a method for operating a combined clutch and brake device (5) of a punch press (1) equipped with dry friction linings (7, 8). Thereby, the friction linings (7, 8) are arranged in a chamber (R) which is sealed off from the environment of the punch press (1), and which is filled with a dry and oil-free gaseous medium, in particular with dry oil-free air. This effectively prevents moisture and oil mist from entering the region of the friction linings from the environment of the press, and a constant friction coefficient can be achieved over the mechanical service life of the friction linings.
A method for operating a combined clutch and brake device of a punch press equipped with dry friction linings, wherein the friction linings are arranged in a chamber which is sealed off from the environment of the punch press and is filled with a dry and oil-free gaseous medium, in particular with dry and oil-free air.
