for machining Carbon Fibre materials
IND-SPHINX Precision Ltd.
AXIS have the right Milling and Drilling solutions designed for machining difficult to machine Carbon-Fiber Reinforced
Plastic (CFRP) and Metal Matrix Composites (MMC).
C
omposites and especially Carbon
fibres are being utilized increasingly
due to their favourable physical and
mechanical properties.
Problems when machining Composites
are :
w Delamination
w Uncut Fibers
w Fiber tear-outs
w Uneven Tool wear
w Poor surface finish
These problems are caused by unique
conditions created by composite
materials, which make it very difficult
to get smooth surfaces.
AXIS Tools for CFRP are optimally
engineered for these applications to
counter the machining challenges.
Our CFRP cutters are available in Coarse,
Medium and Fine cuts.
AXIS Drills for CFRP have special
geometries and coatings with
following features:
w Vibration free operation, excellent
edge retention of holes and milled
surfaces w In case where layer delaminates
sometimes modified geometries are
offered.
w Enhanced tool life w Typical starting values should be
cutting speed of 60-120m/min and
feed rates of 0.02 – 0.15mm/ rev.
w Specially designed geometries AXIS Tool range is made of micro-grain
Tungsten carbides which offer high wear
resistance suited for edge retention and
sharp cutting edges. w Sharp cutting edges with optimised
grinding techniques For machining such materials AXIS
suggests : w PolyCrystalline Diamond tools (PCD)
are sometimes used for higher feed
and sometimes higher speeds. Only
straight cutting edges are possible
with such tools.
w NexGen CVD Diamond coatings w When the material delaminates,
normally feed rate need to be
reduced. CVD diamond tools have harder cutting
edges and can be provided with helical
and wavy edges.
w In case of splintering,use positive
geometry and increase speed and
feed rate AXIS is a leading manufacturer of Rotary
Tools for challenging materials.
Above features offer the following
benefits:
w Reduced cutting forces which enable
clean cutting without fibres and no
delamination of layers
