LMT-Fette is pleased to introduce our new CASTEC® LC620H
turning grade for ductile irons,
malleable irons, and grey iron materials. Cast iron materials
vary greatly in the composition
of the alloy. They also vary in the cool down times,
have different fluctuating physical
properties, and are produced by various casting methods.
These materials are best
machined by means of indexable inserts made from carbide.
LC620H provides K20
substrate carbide that is gradient-sintered to provide
excellent edge toughness. LC620H is a
multi-layer MT-coated grade featuring TiN, TiCN, and
Al2O3 for excellent heat- and
CASTEC® LC620H turning grade is designed with a special,
ceramic layered coating and is
highly resistant to crater wear in abrasive cast iron
materials. The main problem with cast
iron is the heat that is generated during machining,
not chip breaking. This grade reduces
the friction during machining so that less heat is generated,
making dry machining possible
from an economic point of view.
In the development of the CASTEC® LC620H, the focus
was on a tough, carbide substrate
covered with a fine, extremely wear-resistant MT-CVD
layer coating. CASTEC® LC620H
turning grade is a universal turning grade for all cast
iron materials such as ductile,
malleable, and grey iron.
The primary advantage of the new LC620H is its ability
to handle a wide range of cast iron
materials. In difficult turning operations such as high
abrasive materials, LC620H provides
the ultimate crater wear-resistance and tool life. The
new CASTEC® LC620H adds more
flexibility with a wide range of ISO/ANSI indexable inserts.
They allow more productivity
by increased performance, tool life and reduced overall
