Nytt i PFERD-programmet New in the PFERD Product Line

PFERD has further developed the ALU cut
especially for stock removal of aluminium. This
cut is characterised by its high stock removal
performance on all aluminium materials.
Note
You can find the coated tungsten carbide ALU
cut under tungsten carbide burrs HICOAT ® ,
coating HC-NFE.
Please refer to the PRAXIS “PFERD Tools for
Use on Aluminium” for instructions and further
information on working with aluminium.
Recommended rotational speed range
To determine the recommended cutting speed
[m/min], please proceed as follows:
� Select the material group
that is to be processed.
� Determine the type of machining.
Hard non-ferrous
metals
Advantages of ALU cut
� Reduces material adhesion.
� Long tool life.
� Large chip volume and high stock removal
performance.
� Can be used with cutting rates of up to
1.100 m/min.
� Smooth running.
Application examples
� Contouring.
� Bore deburring.
� Milling in preparation of build-up welding.
� Suitable for milling work (deburring, weld
dressing, contouring etc.) Also suitable for
work on small and miniature components in
mould, machine and model construction.
Bronze, titanium,
hard aluminium alloys
(high Si content)
Coarse machining =
high stock removal
Advantages of ALU PLUS cut
� Mainly used for coarse stock removal of
non-ferrous metals, brass, copper, hard
aluminium alloys, plastics, fibre-reinforced
plastics and rubber.
Recommendations for use
The use of grinding oil prevents chips adhering
during work on soft aluminium alloys. This
increases the tool life and improves the finish
of the workpiece.
Refer to catalogue 204 for detailed information
and order data for grinding oil 412 ALU.
