8. Operation and the sawing procedure
Switch on the main DS WS10 drive unit and allow the
wire to start running.
Switch on the main DS WS10-E drive unit and allow the
wire to start running.
The starting procedure
■
The main switch is in the ON position and the “pow-
er” indicator lights green.
■
The advance lever is in the “sawing” (advance) posi-
tion and the sawing wire is under slight tension. All oth-
er switches are set to OFF or “0”.
■
The piston rod is locked in position by way of the return
lock and the locking lever on the carriage has been
released.
■
The water valves are open and cooling water is being
fed directly to the cutting face.
■
Set the advance pressure to approx. 1 to 2 bar at the
control unit by means of the control knob (pull out to
release).
■
Adjust sawing speed to approx. 12–15 m/s (DS WS10-
E or DS WS10 with D-LP 32).
8.3
Use the speed regulator (DS WS10-E) or adjust the oil
flow (D-LP32) to gradually increase the speed of the wire
while simultaneously increasing the advance pressure.
CAUTION
Switch the main drive off immediately if the wire does
not begin to run right away. The drive pulley will suffer
damage if the sawing wire slips while the pulley rotates.
■
Set the advance control valve to the middle (neutral)
position and check whether the sawing wire can be
pulled through the kerf easily by hand. If not, pro-
ceed as follows:
■
Round off corners where the cut is to be made by
chiseling or by pulling the wire through by hand.
■
Remove small stones or fragments etc. that may be
stuck in the kerf.
■
Check and adjust the wire guidance system to ensure
optimum alignment.
Repeat the starting procedure.
Increase speed until the optimum cutting speed is
reached.
Set the pneumatic advance pressure (bar) so that the
electric current indicated is just below the red area on
the gauge (DS WS10-E) or set the hydraulic operating
pressure to a value between 80 and 120 bar (DS WS10).
NOTE
If the cutting arc of the wire is too flat, full use cannot
be made of the electric power available due to inade-
quate effective advance pressure.
