Diamond tools, also known as diamond caking, sawtooth, etc. is generally welded on cemented carbide matrix to form diamond milling tools, drills and other cutting tools.The specific application of diamond tools in rolls is mainly in milling cemented carbide rolls ring /rolls crescent groove, also known as cutting rib, mainly using diamond tool welded by diamond tool head for milling. The diamond tool name for milling cemented carbide rolls ring /rolls crescent groove is PCD rotary milling cutter, which is used with rotary cutter Arbor.Zhengzhou Halnn Superhard specializes in the production of super-hard tools represented by PCD rotary milling tools, and it is also the only unit in the world that can provide a complete set of solutions in the field of machining rolls.Let the world no longer have hard-to-machine materials.
