1.2.2 Feed gearbox
The feed gearbox is mounted on the turntable assembly and provides a variety of
cutting feeds for different machine applications. Drive from the feed gearbox to the
toolpost is via the surfacing arm leadscrew.
Drive input to the feed gearbox is derived from the mast transfer gear. The gearbox
provides four different feed rates, selected via the cutting feed rate push/pull
selector. Traverse direction is selected via the traverse direction push/pull selector,
which selects traverse IN, traverse OUT and neutral N position. The neutral (N)
position can be used for manually positioning of the toolpost and tool. An additional
neutral (N) position is also available by pushing the cutting feed rate selector fully
inwards past the No.4 feed position. This enables the operator to easily disengage
the feed gearbox from any feed.

1.2.3 Surfacing arm assembly and toolpost
The surfacing arm assembly is mounted on the turntable assembly and provides a
rigid structure to which the tool post is secured. The arm can be positioned at any
diameter within the recommended facing range.
Toolpost feed in and out is provided by a leadscrew which is driven by the gearbox
pickup gear. The surfacing arm assembly can achieve cuts to a maximum depth of
1.0mm (0.040in) in flanges without bolt holes and 0.5mm (0.02in.) with bolt holes.
Alternative tools can be fitted to the tool post depending on the finish and cut
required.
