Like the SA150 precision surface abrader, the SA3000, will abrasively clean or
texture thin flat parts up to 300mm wide, 300mm long and up to 20mm thick.
The system comprises of a Comco DF1400-2CE abrasive blaster or Comco
PF2400-2CE, which sits
underneath the main unit on a gurney. Connected into the back of the main
table is an extract port for connecting to a suitable dust extractor.
The
standard machine occupies a floor area approximately 1000mm x 1000mm and the
conveyor height is 1100mm from the floor. The overall conveyor is 900mm long
and is 300mm wide. Abrasion resistant polyurethane belts make up the conveyor
belt.
The abrasive blast area is enclosed so that very little dust will escape
with the correct extraction flow. The chamber is illuminated and has a large
front window so the operator may view the part being processed. The blast
enclosure is fixed on a hinge at the back of the cabinet and can be lifted to
allow adjustment or changing of the blast head. As standard the machine comes
fitted with two nozzles, however, we are able to offer single nozzle and
triple nozzle heads if needed.
Parts are placed on the conveyor belt on the left hand side of the machine
and are run under a laser sensor, which automatically detects the front
leading edge of the part. Parameters for part length, pass width, pass speed,
the number of passes across the part, the index distance between passes, and
the reprocess steps, can all be changed via the SA3000 control panel. A save
feature allows the current process parameters to be saved into memory.
The automatic conveyor belt passes through the blast chamber, underneath
the two blast nozzles. The forwards/backwards motion is controlled by the
pass speed and pass width parameters within the settings. Left to right
motion is pre determined for the conveyor speed. A large window is on the
front of the blast chamber allowing the operator to see the parts being
processed and to monitor their progress. The blast chamber is also fitted
with a lamp to aid visibility during use of the machine. The control panel on
the right hand side allows the user to change the process parameters quickly
and easily for the system.
Adjustable side plates allow for larger components to be passed through
the machine and to allow adjustment on the extraction airflow. The blast
chamber is hinged to allow full access to the head for setting the height of
the blast nozzles. The nozzle height is adjustable depending on the thickness
of the part being processed.
Safety interlocks prevent the machine from being run when there is no dust
extraction present, or when the protective blast chamber is open. Whilst
abrasive blasting is in progress, if there is a drop in pressure or
extraction or if the blast cabinet is opened, the SA3000 will stop the cycle
to prevent any damage or danger to the parts being processed.
The entire nozzle drive mechanism is enclosed to exclude dust. The nozzle
drive arms in the top of the abrasive chamber are completely covered with
extendible bellows.
The whole system requires clean, dry air. A 220v, 50Hz power supply for
the SA3000 is required. The DF1400-2CE is powered directly from a special
socket on the SA3000. The Filtex FX50H requires a separate 400v, 3 phase power
supply and for the control box to be mounted at a convenient location near
the dust extractor.
