Geometry RS

Machining of aluminium and

non-ferrous materials

Many components are made in aluminium or other

non-ferrous materials such as copper, brass, bronze but

also plastic materials.

A common feature with these materials is that a

sharp edge and an open chip breaker is needed to be

successful. In order to achieve these sharp edges, nor-

mally the edgeline has to be ground and the carbide

needs to be either uncoated or with a thin coating.

Grade GC1005 is recommended as first choice for roughing operations and sharp edged H10

or H13A for finishing operations.

For components demanding extreme high surface finish a diamond tipped insert is recom-

mended as it gives the possibility of using high cutting data and to achieve long tool life.

Recommended grades and cutting data

Grade GC1005 for roughing, grade H10 and H13A for finishing.

Cutting speed 300 m/min and higher, feed 0.2 mm/r.

Profiling

The AM geometry in grade GC1005 and

H10 is designed for these materials and

combined with the superior stability of the

CoroCut system it is also suitable for pro-

filing of aluminium wheels. When extreme

surface finish is required the CoroCut 1-edge

insert with diamond tipped RS geometry in

grade CD10 should be used.

Grooving/Parting

For grooving and parting operations GF

geometry in grade H13A is a good choice. If

there is a need for pip and burr free machin-

ing the sharp CS geometry in grade GC1125

is first choice.
