Face milling test result
Chips of TANG4FEED are shorter compared to other tools.

SCM440 (Vc=120m/min、fz=1.0mm/t、ap=1.0mm、ae=45mm)
SUS304 (Vc=120m/min、fz=1.0mm/t、ap=1.0mm、ae=45mm)




Shoulder milling test result：Compared to other tool, machining sound volume of TANG4FEED is smaller and cutting power is also lower.

SCM440 (Vc=120m/min、fz=1.0mm/t、ap=1.0mm、ae=20mm、Overhang=260mm)




Helical coutouring milling test result：
Helical coutouring milling test resultTANG4FEED has high surface quality.
Machining sound volume is smaller compared to other tools.

SCM440　(Vc=120m/min、fz=1.0mm/t、
Pitch=1.0mm[Ramp down angle：0.4゜]、Overhang=260mm)

 Appealing sales points and attention

  • New design insert

    Large lapping angle is available by new insert design.

  • Strong dovetailed insert clamping

    Stable machining by strong dovetailed insert clamping even at large cutting force.

  • Recommended machine

    Since insert corner areas are large design, machine rigidity and workpiece rigidity are necessary.
