Method for producing clutch and brake disks for electromagnetic clutches or electromagnetic brakes having at least one friction surface element

A method for producing clutch and/or brake friction disks for electromagnetic clutches and/or electromagnetic brakes having at least one friction surface element through which a magnetic field flows, comprising the steps of:

• cutting at least one circular slot by lathe machining the at least one friction surface element from a friction contact surface toward a surface opposite to the friction contact surface to define at least a first and a second pole surface ring, one on each side of the at least one circular slot;
• and forming at least two webs which connect on the surface opposite to the friction contact surface, wherein the at least two webs connect the first pole surface ring to the second pole surface ring such that the at least one circular slot cut from the friction contact surface is interrupted by the at least two webs to form continuous air gaps between the at least two webs.
