4.11 Drill chuck
ATTENTION!
Make sure that the clamped tool is firmly and correctly fitted.
4.11.1 Unfitting the drill chuck
The drill chuck and the taper mandrel are loosened from the drill spindle by means of a drill
drift.
PRECAUTIONARY MEASURE
Only disassemble the drill chuck if the drilling
machine is disconnected from the electrical supply.
Disconnect the machine from the electrical supply.
Move the drill sleeve down.
Turn the drilling spindle until the openings of the
sleeve and of the drilling spindle are superimposed.
Loosen the taper mandrel of the drill chuck with the
help of a drill drift.
4.11.2 Fitting the drill chuck
The drill chuck is secured in the drill
spindle against turning over by means of a
form-locking connection (driver).
A frictionally engaged connection keeps
and centres the drill chuck or the drill in the
drill spindle.
Abb.4-1: Taper mandrel
Check and clean the conical seat in the drill spindle and on the taper mandrel of the tool or
drill chuck.
Press the taper mandrel into the drill spindle.
4.12 Cooling
The friction generated during rotation can cause the edge of the tool to become very hot.
The tool should be cooled during the drilling process. Cooling the tool with a suitable
cooling lubricant ensures better working results and a longer edge life of the tools. This is best
realised by a separate cooling equipment. If there is no cooling equipment included in the deli-
very volume, you can cool by means of a spray gun or a washing bottle.
CAUTION!
Danger of injury due to brushes getting caught or pulled in. Use a spray gun or a
washing bottle for cooling.
