product description

Cutting teeth are key components for directly cutting coal and rock on mining units, and are vulnerable parts. The main failure mode is wear failure, and the main form of wear failure is the wear of the cutting tooth end base, which leads to the peeling of the alloy head. The poor wear resistance and short service life of ordinary domestic gear cutters increase the intensity of underground operations and reduce production efficiency.

After adopting laser cladding technology, the average microhardness of the cutting teeth is HV800, and the Rockwell hardness is 65HRC; The average microhardness of laser alloyed cutting teeth is HV1099, and the Rockwell hardness is 70HRC; The average microhardness of laser quenched cutting teeth is HV750, and the Rockwell hardness is 62HRC. Laser cladding and alloying process coatings are metallurgically bonded to the substrate, with high bonding strength.

Through experiments, the surface hardness and wear resistance of laser strengthened cutting teeth have been significantly improved, and the service life of cutting teeth has been significantly extended. Compared with ordinary cutting teeth, laser cladding cutting teeth have a 3-4 times longer lifespan, and surface alloying cutting teeth have a 5-6 times longer lifespan.
