Carbide Tips Metal Cutting Carbide Inserts
Tungsten carbide cutter head has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, even at 500℃ is basically unchanged, still has a high hardness at 1000℃.
1, welding cutting carbide tips structure should have enough rigidity
Sufficient rigidity is ensured by the maximum allowable external dimensions and by the use of high strength steel grades and heat treatments.
2, hard alloy blade should be fixed and reliable
The cemented carbide welding blade should have enough fixed firmness, which is guaranteed by the slot and welding quality, so the slot shape of the blade should be selected according to the shape of the blade and the geometrical parameters of the tool.
3, carefully check the knife rod.
Before welding the blade to the tool bar, necessary checks should be made on the blade and the tool bar, first of all, check that the supporting surface of the blade is not severely bent.The cemented carbide welding surface shall not have serious carburizing layer, and the dirt in the cemented carbide blade surface and tool bar insert groove shall be removed to ensure the welding is firm.
