Milling, as a common processing method in the machining industry, uses a Milling cutting tools as a machining tools for
machining the surface of an object. Milling includes face milling and surface milling. Milling cutting tools are also divided
into face milling cutting tools, end milling cutting tools, ball end milling cutting 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 workpieces,
and milling is more susceptible to vibration than turning. Therefore, the performance requirements of milling cutting tools are
more stringent.
Halnn, Since its inception, it has adhered to the initial business philosophy of “not seeking big and complete, only high
precision”. It focuses on the research of CBN tools for brittle and hard materials. Its milling cutting tools have been tested
for a long time, and recognized by the market and has gradually replaced the European CBN milling cutting tools for the
high-end market in China.
Halnn CBN 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 tool, high hardness / strength steel is recommended BN-S20
grade CBN tool, gray cast iron is recommended BN-S300 grade CBN tool, and of them are solid CBN tools as above, which
not only have high hardness and wear resistance, but also have high impact toughness and fracture resistance.
The following is an introduction to the advantages of Halnn CBN tool application in milling.
