KORLOY has launched a new Cermet series, CN1500 and CN2500, for high efficient machining of cold/hot
forging and sintered ferrous materials for automobile and machinery.
The general troubles with using cermet grades in finishing cutting are insufficient geometry and surface roughness. The insufficient geometry accuracy happens mostly under the condition of deformation on a cutting edge of which wear resistance is not enough for high speed machining. The latter, bad surface roughness, is caused by chipping and fracture on the blade in high feed and high interrupted machining.
In order to prevent deterioration of the cutting edge, solid particles (TiCN) have been evenly spread out in the substrate of cermet. Optimized cutting edge brings maximized stability on cutting and reducing deviation on the available inserts
CN1500 is in the area of P15 grades for high speed and continuous machining, while CN2500 is in the area of P25 grades for high speed and high feed operation over 0.2 mm/rev, and high interrupted machining.
Not only that, CN1500 and CN2500 match the combination of chip breakers such as negative types, VL-VB-VQ, and positive types, VL-VF-MP, which enables excellent chip control and low cutting loads.
