Reasonably Foreseeable Misuse; Avoiding Misuse - Optimum optimill MH25V Betriebsanleitung

WARNING!
Extremely severe injuries due to non-intended use.
It is forbidden to make any modifications or alternations to the operating parameters
values of the milling machine. They could pose an accident hazard to persons and cause
damage to the milling machine.
1.4

Reasonably foreseeable misuse

Any use other than that specified under "Intended use" or any use beyond that described will be
deemed non-intended use and is not permissible.
Any other use must be discussed with the manufacturer.
Only metallic, cold and non-flammable materials may be machined with the milling machine.
In order to avoid misuse, the operating instructions must be read and understood before first
commissioning.
Operators must be duly qualified.

1.4.1 Avoiding misuse


Use of suitable cutting tools.

Adapting the speed setting 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
processing 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 must always be fixed in a machine vice, chuck or by another appropriate
clamping tool such as 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 positioned exactly between the three clamping jaws of the
drill 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
