Sandvik Coromant announce new drilling solutions for CFRP composites at Paris Air Show
Aerospace manufacturers looking to improve the drilling of components made from carbon fibre reinforced plastic (CFRP) composite materials used increasingly in wing, fuselage and tail assemblies should make their way to the stand of Sandvik Coromant at the forthcoming Paris Air Show (15-21 June). Visitors to the stand will learn of three new drill geometries designed to both enhance performance and extend the number of CFRP composites that can be processed efficiently by the increasingly popular CoroDrill Delta-C family.
Building on the success of CoroDrill Delta-C R854 – the original geometry for drilling
aerospace components manufactured from CFRP composite – Sandvik Coromant will
announce details of three new innovative geometries at the Paris Air Show 2009.
“The existing CoroDrill Delta-C family includes sharp geometries for reduced splintering
and a unique geometry for getting rid of delamination – both common when trying to drill
CFRP composite stacks in a single operation,” explains Francis Richt of Sandvik
Coromant’s applications management team. “However, high demands on solutions to
drill holes within certain specifications such as surface finish and tolerance, ensure we
keep looking for new geometries to enhance performance and broaden the number of
CFRP composite types we can process. Composite materials and the use of composites
is under rapid advancement, hence variations of drill geometries are essential to
process materials with high resin or high fibre content.”
Available this summer, the three new geometries will at first be supplied as part of
Sandvik Coromant’s ‘Tailor Made’ programme in line with specific customer
requirements, with standard stocked items set to follow later in the year.
The winning formula of fine-grain carbide substrate, innovative geometries and diamond
coating is proving increasingly popular among aerospace manufacturers seeking a
competitive advantage in increasingly tough economic conditions. The easy cutting
action offers more accurate holes with less friction through sharper cutting edges, while
reduced axial pressure decreases deflection in thin-walled parts, helping to minimize
common problems.
“An alternative option that is also proving popular is our PCD (polycrystalline diamond)
tipped solution,” says Mr Richt. “The diamond tipped drills are made to suit the
application, machine type or customer requirement, so both brazed or vein designs are
possible solutions for increased productivity.”
Additionally, Sandvik Coromant offers a number of solutions for surfacing, edging and
trimming of CFRP composites, including various types of brazed or indexable milling
cutters.
“At Sandvik Coromant we are continually developing new process solutions for
machining composite materials,” says Mr Richt. “This includes not only cutting tools but
also new ways of applying the tool and other possible solutions that are not yet in
widespread use today. Our endeavours are designed to support customers in achieving
increased productivity and improved hole quality in these difficult to machine materials.”
