BNK30 RNEN090300 Solid CBN Cutting tools face milling Cast iron Cylinder head with
high efficiency
1. Halnn Tools BNK30 RNEN090300 CBN Cutting tools face milling Cast iron Engine Block
Engine Block is one of the most important parts of engine, and is
the base of the engine. Engine Block is the typical case parts, and
it usually uses milling process machining all surface. And the
engine block usually require high on the product quality, and
surface roughness, ect. So it requires high on the cutting tools,
which will need high cutting speed, high precision and high
efficiency.
2. Why we Choose Halnn Tools BNK30 RNEN090300 Solid CBN Cutting tools face milling
Cast iron Engine Block ?
The materials of engine block are gray cast iron, and have low
hardness. Traditional cutting tools can machine. But for the high
requirements on the engine block, traditional cutting tools(carbide
insert, ceramic cutters and coating carbide insert) can’t satisfy
all the requirements, many manufacturers use famous brand (Seco,
Sandvik ) Insert for milling and boring prosess.
CBN Insert has high hardness, stable performance and long tool
life, also can obtain good product quality, so it often is used for
milling engine block with high cutting speed. Especially Halnn
BN-S300, BNK30 and BN-K20 PCBN inserts, is the most widely used for
milling and boring engine block.
And BN-S300 belong to solid cbn insert, mainly used for milling
engine block, BN-K20 and BNK30 are brazing pcbn insert, are mainly
used for boring process to make sure high surface quality and long
tool life. And all of them have been widely used.
