Conventionally for cast iron as well
as sg iron carbide tools in coated
as well as uncoated grade are used.
Low cutting speeds as well as less
tool life are the 2 constrants which
makes cast iron machining more tedious
and high machining cost. Sumitomo
has made pioneering efforts in usage
of CBN as a cutting tool material
in general and cast iron machining
in specific. Their long experience
of tool failure analysis and efforts
to improvement tool life with changing
grade compositions, binders, alloys,
coating and edge treatment has resulted
in 4 different grades for cast iron
as well as ductile cast iron machining.
Motherson CBN being most hard
material ideally recommended first
choice for higher speed, same resulted
in productivity, efficency and lower
machine cost for area of cast iron.
Motherson CBN encures excellent
surface finish, reduction in cycle
time, reduction in tool change time,
consistency of bore while machnining
long lengths in close tolerances.
Sumitomo offering BNX10, BN500,
BN600 and a Grade
BNS800 which covers the whole
range of cast iron compositions.
Application areas as well as recommended
parameters for excellent benefits
are given below for your ready reference.
