Why PCBN tools insert is fit for the thermal spray welding materials machining? Which is mainly due to the characteristics of the materials.

Thermal spray welding generally includes, but is not limited to, nickel-based alloys, iron-based alloys, and cobalt-based alloy spray powders.

Spray hardness is sprayed according to different alloy spray coatings, which are applied to the repair of mechanical parts or to increase the surface properties of metal; The thickness

can be from 0.01 to a few mms; the hardness of the spray coating/spraying layer is generally above HRC50, and the hardness of the spray-welded layer and the sprayed layer of parts

requiring wear resistance is generally between HRC55-65, and the hardness of some spray-welded layers exceeds HRC65. Machine tools for spray-welding and spray coatings have 

always been a challenge to limit hard-faced post-processing techniques.

Such as RNGN090400 solid cbn inserts for WC tungsten carbide spray-welding layer materials machining, the tool life and machining efficiency is highly improved.
