2. Assembly of a Table Circular Sawing Machine
Figure 2 Assembly of a
table circular sawing machine 1 stand, 2 receding table, 3 stop for
cross and angle cuts, 4 splitting wedge, 5 guard hood, 6 saw blade, 7 machine
table, 8 stop rule
Stand
The stand bears the machine table and movable receding table and
also houses the height-adjustable motor.
Machine table
The machine table is directly attached to the stand and serves
to direct the workpieces to the saw blade.
A stop rule which is adjustable and parallel to the saw blade is
on the machine table - to the right of the saw blade. This stop rule serves to
set the width of oblong cut workpieces.
Receding table
This is positioned in a movable manner vis-a-vis the stand and
serves to undertake cross and angular cuts whose angle setting can ensue by
means of a stop.
Motor, motor shaft and saw blade
Motor and motor shaft can be adjusted up to an angle of 45°
by means of hand wheels. The saw blade is attached to the saw shaft by means of
two flanges and a chucking nut.
Figure 3 Adjusting the saw
blade 1 saw blade at maximum angle setting at 45° - motor swiveling,
2 saw blade in vertical position with motor in horizontal position, 3 hand
wheels to adjust the motor
The table edges close to the saw blade and the machinable
material are interchangeable.
The distance between saw blade and table edges must
not be greater than 3 mm in order to prevent the drawing in of narrow wood
pans!
Protective facilities
Splitting wedge and guard hood are protective devices of the
circular sawing machine. The machine shall not be used without these protective
facilities, otherwise considerable accident risk!
The splitting wedge is adjustable and aligned to the
curve of the saw blade whereby the distance from saw blade shall not exceed 10
mm!
Figure 4 Required protective
distances 1 machine table, 2 splitting wedge, 3 guard hood, 4 workpiece, 5
saw blade
The splitting wedge is safeguarded from slipping, adjusting or
moving upwards and shall keep apart the separated workpieces thereby ruling out
upward and backward sliding of the workpiece. The guard hood is attached to the
splitting wedge and consists of machinable material. The saw blade is thus
covered up from above. Chips arising are deflected through an escape slot.
The guard hood must protrude 20 mm above the cutting
circle of the saw blade feed in the machine table!
Distance of guard hood to workpiece surface shall not exceed 8
mm in rest position!
During the cutting operation the guard hood shall only expose
the saw blade section required for cutting. After the cutting operation is over
the saw blade must be completely concealed.
If these hints are not observed serious accidents
may result!
