SECTION 1 TECHNICAL DESCRIPTION
1.1 INTRODUCTION
The TEAM® SX28-72 Flange Facing Machine is constructed from the highest quality materials
and great care has been taken in its design and manufacture. Its design will give every
satisfaction provided that it is properly installed, operated and maintained in accordance with
the information contained within this manual.
Take care of this manual; it is an essential source of information.
1.2 EQUIPMENT DESCRIPTION
The SX28-72 Flange Facing Machine is designed to machine full face, raised face and
grooved flanges from 711mm to 1829mm (28" to 72") in diameter at any location having a
minimum pneumatic air supply of 1.8 m3/m at 6 bar (64 cfm, 87 psi).
The machine can achieve a variety of surface finishes from 6.3μm RA to 1.6μm RA when
turning and 1.6μm RA to 0.8μm RA when polishing. The machine can also produce a
'gramophone' finish, 'O' ring grooves, and 'V' grooves.
The machine consists of 3 main assemblies:
1. Main drive assembly
2. Surfacing arm assembly and toolpost
3. Mounting base assembly
1.2.1 Main drive assembly
The main drive assembly consists of 3 sub-assemblies:
1. Turntable
2. Base plate assembly
3. Feed gearbox

Fig. 3 Main drive assembly
1. Turntable
The turntable is the rotating part of the machine providing a rigid support for the
gearbox, motors and surfacing arm assembly.
The turntable is driven by two air motors attached to its top face. The drive from the
motors is passed through two intermediate gears to a drive gear on the main bearing
under the turntable. Air for the motors is fed from the central mast through a rotary
seal.
2. Base plate assembly
The base plate assembly is the fixed part of the machine and comprises of a base
plate which is clamped to the mounting base assembly, a mast gear used for the
gearbox drive, and a centre mast.
3. Feed gearbox
The feed gearbox is mounted on the turntable 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 transmitted via the mast transfer gear. The gearbox
provides four different tool 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.
Fig. 4 Feed gearbox
1.2.2 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
output 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.

1.2.3 Mounting base assembly
The mounting base assembly is provided to enable the machine to be installed in
the centre of any bore from 711mm (28") to 1727mm (68") in diameter.
The mounting base assembly consists of a central hub with four radial location
bosses. The bosses allow extension legs, collars and the clamping jaw assemblies
to be fitted to the base to suit the internal diameter of the flange to be machined. The
extension legs and collars are precision manufactured with locating flanges to
ensure perfect alignment when fitted correctly.
The design and manufacture of the base and extension legs ensures a rigid machine
mounting structure.
The mounting base is usually installed in the flange bore prior to the machine
installation.
