Milling, as a common processing method in the machining industry, uses a milling 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 tools 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 tools, high hardness / strength steel
is recommended BN-S20 grade CBN tools , gray cast iron is recommended BN-S300 grade CBN tools are solid CBN
tools, 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 tools milling various materials.
