Semi-universal Dividing Head

Type F12 series and FB80,the semi-universal dividing head,is one of the mostimportant attachmentfor milling machine.With the help of this dividing head,the workpiese can be carried out direct indexing and simple indexing,orrotate to any angle as desired and the periphery of a workpiece can be divided into any divisions ofequal parts and etc. The operation handle of type FB80 is on the left,F12 series is on the right.
