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.
