[1] The universal dividing heads, models UDH80, UDH100, UDH125, UDH160 are the most important attachments for millers. With the help of the dividing head, the workpiece held between centers, or on a chuck can be rotated to any angles as desired and the periphery of a workpiece can be divided into any divisions equally. By means of all kinds of cutters, the dividing head can also help the miller to perform the milling operation for flute, spur gear, spiral gear, spiral flute, Archimedean cam, helical flute, etc..
[2] The dividing head is equipped with a face plate than can be mounted onto the spindle nose. The workpiece can be fixed on the face plate, thus, cutting can be carried out from all the sides of workpiece.
