Construction of machine is similar to that of conventional
type Rotators. However, Housing Brackets are supported directly on the machine bed and are attached to the bed only with an L.H./ R.H. Lead Screw and nuts. When the Lead Screw is rotated with the ratchet handle, the Roller Brackets move simultaneously towards each other or away from each other. In this series there will be twin drive arrangement. This type of design provides simultaneous and step less adjustment of the Roller housings, and keep the job axis always at the same position irrespective of diameter setting.
