1.4.1 Avoiding misuse
Use of suitable cutting tools.
Adapting the speed adjustment and feed to the material and workpiece.
Clamp workpieces firmly and free of vibration.
Risk of fire and explosion due to the use of flammable materials or cooling lubricants.
Before processing inflammable materials (e.g. aluminium, magnesium) or using inflamma-
ble auxiliary materials (e.g. spirit), you need to take additional preventive measures in order
to avoid health risks.
When processing plastics, the machine operator must ensure that static electricity gener-
ated during the machining process can be discharged easily.
When processing carbons, graphite and carbon-fibre-reinforced carbons, the machine is no
longer being used as intended. This causes the warranty to be null and void. When pro-
cessing carbons, graphite and carbon-fibre-reinforced carbons and similar materials, the
machine can be damaged extremely quickly, even if the dusts generated are completely
sucked out during the work process.
ATTENTION!
The workpiece is always to be fixed by a machine vice, jaw chuck or by another
appropriate clamping tool such as for the clamping claws.
WARNING!
Risk of injury caused by flying workpieces.
Clamp the workpiece in the machine vice. Make sure that the workpiece is firmly clamped in
the machine vice and that the machine vice is firmly clamped onto the machine table.
Use cooling and lubricating agents to increase the durability of the tool and to improve the
surface quality.
Clamp the cutting tools and workpieces on clean clamping surfaces.
Sufficiently lubricate the machine.
Set the bearing clearance and guides correctly.
Recommendations:
Insert the drill in a way that it is exactly positioned between the three clamping jaws of the
quick action chuck.
Clamp end mills (or shank cutters) in a collet chuck using the corresponding collets.
Clamp end face mills using shell end mill arbors.
When drilling, make sure that
the suitable speed is set depending on the diameter of the drill,
the pressure must only be such that the drill can cut without load,
if there is too much pressure, the drill will wear quickly and may even break or jam in the
borehole. If the drill gets jammed immediately stop the main motor by pressing the emer-
gency stop button,
use commercial cooling/lubricating agents for hard materials, e.g. steel and
generally always back the spindle out of the workpiece while it is still turning.
ATTENTION!
Do not use the quick action drill chuck for milling tools. Never clamp a milling cutter into a quick
action drill chuck. Use a collet chuck and appropriate collets for end mills.
When milling, ensure that
the right cutting speed is selected;
for workpieces with normal strength values, e.g. steel, 18-22 m/min,
for workpieces with high strength values, 10-14 m/min,
the pressure is selected so that the cutting speed remains constant,
