The SX2872 machine covers a range of flanges from 711mm (28\u201d) internal diameter to 1829mm (72\u201d) external diameter. The turntable incorporates twin 1.7kW (2.3hp) pneumatic motors, which are designed to compensate for the backlash normally found in spur gear drive systems.

It consists of a cruciform body provided with four adjustable clamping jaw assemblies. The mounting base is installed and aligned prior to the turntable installation.

The use of two motors enables the overall machine height to be reduced.  Feed Gearbox  The drive gearbox is mounted on the turntable assembly providing a variety of cutting feeds for different applications. Drive input to the gearbox is derived from the mast transfer gear. The gearbox provides four different feed rates selected by a push\/pull selector.
