Drilling with core drills
When drilling with core drills, proceed as
follows:
Install the quick-change drill chuck
system (A) and connect up the cooling
lubricant system.
Install the appropriate ejector pin
in the core drill and insert the core
drill into the quick-change drill chuck
system (A).
Position and fix the machine at the
location of use.
Switch on the clamping magnet and
check the magnetic holding force (see
section
“Activating/deactivating the
magnetic clamp”
).
Select a suitable speed and switch on
the machine.
Direct the drill to the material with the
handle (10).
NOTE
Observe the following instructions when
drilling with core drills:
►
Drilling with core drills does not require
great force. The drilling process is not
accelerated by higher pressure. The
drill wears faster and the machine can
be overloaded.
►
Use the high-performance BDS 5000
cutting oil in the cooling lubricant sys-
tem of the machine.
►
The cooling lubricant system cannot
be used when working overhead. In
this case, use the high-performance
ZHS 400 grease spray. Spray the drill
on the inside and outside before drill-
ing. In the case of larger drill depths,
repeat this procedure.
►
Make sure that swarf is removed regu-
larly. With larger drilling depths, break
up the swarf.
Eliminating blockages
WARNING
Danger of cut injuries from broken
tool parts or swarf .
►
Put protective gloves on before start-
ing work.
Blockages caused by a broken tool:
Switch off the machine. Remove plug
from the mains socket.
Move the machine slide to the upper
position with the help of the hand
lever (10).
Replace defective tool. Remove swarf.
Other blockages:
Switch the machine off using the motor
switch. Leave the magnetic clamp
switched on.
Move the machine slide to the upper
position with the help of the hand
lever (10).
Remove swarf and check tool.
NOTE
►
The BDS range of accessories
includes special devices (e.g.,
POW 200) for removing swarf.
