Milling, as a common processing method in the machining industry, uses a milling cutting tool as a machining method for machining the surface of a workpieces. Milling includes face milling and surface milling. Milling tools are also divided into face milling tools, end milling tools, ball end milling tools, and the like. At the same time, according to the size of the workpiece to be machined, the milling machine is divided into bench milling machine, plane milling machine, portal milling machine, copy milling machine and special milling machine.

Advantages of Halnn CBN Inserts in Milling
Milling, as a common processing method in the machining industry, uses a
milling cutting tool as a machining method for machining the surface of a
workpieces. Milling includes face milling and surface milling. Milling tools are
also divided into face milling tools, end milling tools, ball end milling tools, and
the like. At the same time, according to the size of the workpiece to be
machined, the milling machine is divided into bench milling machine, plane
milling machine, portal milling machine, copy milling machine and special
milling machine.
In the milling process, the accuracy of the milling machine itself directly affects
the dimensional accuracy of the machined parts, and milling is more
susceptible to vibration than turning. Therefore, the performance requirements
of cutting tools are more stringent.
Halnn tools since its inception, has adhered to the initial business philosophy of
“not seeking big and complete, only high precision”. It focuses on the research
of CBN inserts for brittle and hard materials. Its milling tools have been tested
for a long time. Market recognition and the replacement of imported CBN
milling tools for the high-end market.
Halnn CBN milling tools mainly mill high hardness cast iron, high hardness /
strength steel, gray cast iron and other materials, such as high hardness cast
iron is recommended BN-K1 grade CBN inserts, high hardness / strength steel
is recommended BN-S20 grade CBN insert, gray cast iron is recommended
BN-S300 grade CBN inserts are solid CBN inserts, which not only have high
hardness and wear resistance, but also have high impact toughness and
fracture resistance. It is currently the milling tools brand for milling high
hardness materials.
The following is an introduction to the advantages of Halnn CBN inserts milling
various materials.
