LKM 880

LKM 880

Thanks to its high toughness and wear resistance, the LKM 880 enables large metal removal rates due to the considerable cutting values of a vc of up to 2000 m/min and a feed per tooth of up to 0.25 mm. The roughing and rough finishing of GJL (GG) and GJS (GGG) workpieces are carried out by the LKM 880 extremely economically and reliably. Tool life can be increased significantly when machining cast iron materials with the LKM 880 cutting material.
