Vertical hub forming machine

The WF machine NAM 600/S is a consistent further development of WF machine NAM 600 which has long since been established on the world market. By using all the benefits of the WF patented process for spinning/forming hubs, the higher drive rating and forming forces of the machine NAM 600/S make the production of hubs having a greater wall-thickness and length possible. Motor and transmission components with such hubs, for example, are used in truck and commercial vehicle construction, marine engine construction or in stationary motor construction as torsional vibration dampers, clutch housings or disk carriers. The NAM 600/S is able to produce these components from high-strength materials.  Circular blanks or, in particular cases, forged pre-forms are used as starting material. Depending on the requirements, the machine can also be used for hot spinning/forming, this means for example that the hubs can be spun and/or formed from blanks or pre-forms which have previously been heated to approx. 600-800°C.
