Advantages of Halnn CBN Milling Tools
The hardness of CBN materials is second only to diamond, and the Rockwell hardness is HRC95-100, which can easily mill hardened steel planes.
CBN inserts are matched with high-precision milling cutters to realize high-speed intermittent milling with high efficiency and high precision.
The outstanding new nanocomposite coating makes it more closely integrated with the substrate, has excellent wear resistance, oxidation resistance and lubrication performance, lower friction, greatly improves the durability of the end mill, and ensures hardened steel The surface quality of the piece after milling.
The professional spiral groove and helix angle design of the coated end mill realizes the good chip removal of the milling cutter and ensures the stability during high-speed milling.
Halnn Coating carbide Miling tools
For the different needs of Hardened steel milling, the coating materials are also different. Common coatings are: ALTIN coating, TIALN coating, TISIN coating, etc.
Hardness HRC45-62: Choose ALTIN coated milling cutter;
Hardness below HRC55: Choose TIALN coated milling cutter and TISIN coated milling cutter
