BN-K1 garde is a CBN tool developed by Halnn Superhard in 2003, which undertook a national key "production, education, and research" project, targeting high chromium white cast iron, high manganese steel, etc. Its excellent cutting performance has sparked a revolution in cutting technology in wear-resistant castings such as high hardness castings.
BN-K1 CBN cutting tools are a national patented product that uses non-metallic ceramics as the adhesive. They have excellent wear resistance, heat resistance, strong impact toughness, and fracture resistance. In the face of severe work hardening of the rolling mortar wall, BN-K1 CBN cutting tools can be used to rough turn the rolling mortar wall with a large margin, minimizing the number of tool passes and improving production efficiency.
In addition, BN-K1 CBN tool can also withstand intermittent cutting conditions. For example, Casting defect such as sand inclusion and hard spots will inevitably appear on the surface of large cast mortar wall. At this time, BN-K1 is selected to process the rolled mortar wall. It can be directly processed without grinding or reducing the depth of cut. Not only does the cutting edge not collapse, but also ensures a long tool life and reduces production costs.
The BN-K1 brand is widely used in wear-resistant castings such as rollers and slurry pumps, in addition to efficiently processing the rolling mortar wall.
Hualing Superhard, a pioneer in the field of professional hard material processing tools, has been focusing on the research direction of CBN tools and high-grade diamonds for brittle and hard material processing for more than ten years. It enjoys a high reputation in the academic field of superhard tools, especially in sub fields such as "replacing grinding with turning", ultra-high hardness heavy-duty cutting, and high-speed machining of cast iron. At the same time, new CBN/PCD tools and other new material tools have been constantly introduced in the 3C industry, aerospace, nuclear and military fields according to the innate resources of the Superhard material Research Institute.
