Z Mill
The full name for z mill is Sendzimir mill. A Z mill operates with a very small diameter work roll, normally about 2 inches, backed up by a number of rolls in a pyramid shaped stack. This roll set up allows you to exert extremely high forces through the work roll and yet keep the work roll from extreme flexing. The take up roll on the Z Mill also exerts a tension on the coil as it comes through the mill. The combination of high pressure and tension makes the mill capable of rolling material thin and flat.
