1) Our PCBN milling cutter are mainly used for milling gray cast iron, hardened steel; the main industries are automotive industry (engine, gearbox, etc.), machine tool industry (rail, workbench), mining machinery industry (wear plate).

2) Large cutting force, mainly processing solid and thick-walled box parts; preferred high-power machine tools. For installation 40 Milling machine with taper shank, the diameter of the milling cutter should not be large: φ63 is preferred, followed by φ80.

3) Dry cutting. It is best if there are air-cooled or atomized cooling conditions.

4) Up milling.

5) When rough milling gray cast iron:  Ap=2-5mm, Vc=400-1000m/min, fz=0.1-0.2;

    When finishing gray cast iron: Ap = 0.2-0.5 mm, Vc = 500-2000 m/min, fz = 0.1-0.2;

    When rough milling hardened steel: Ap=2-5mm, Vc=100-200m/min, fz=0.05-0.15;

    When finishing hardened steel:  Ap = 0.2-0.5 mm, Vc = 150-300 m / min, fz = 0.05-0.1;

    The ap is larger, the Vc and fz is smaller.
