Tungsten Carbide Cutting Tools Material Selection

Current product technology from the tool, the tungsten carbide cutting tools gradually replace high-speed steel cutting tools, in particular circular tool. Coated tungsten carbide cutting tools are becoming more common, according to the main chemical components distinguish tungsten carbide cutting tools can be divided into groups based tungsten carbide and titanium tungsten carbide tungsten carbide cutting tools. Including tungsten carbide cobalt-based alloy (YG), tungsten, titanium, cobalt class (YT) and add carbonation rare class (YW) three main components of tungsten carbide (WC), titanium tungsten carbide (Tic), niobium tungsten carbide ( NbC), commonly used metal bonding phase is Co. Tic titanium tungsten carbide tungsten carbide based cemented tungsten carbide is the main component, commonly used metal bonding phase is Mo and Ni.

The correct selection of a suitable cutting tool material, can improve work efficiency, improve processing technology has important significance machinery manufacturing needs. We know that, in addition to cutting tool materials should have the hardness and wear resistance, strength and toughness and economy, the tungsten carbide cutting tools must also meet the following requirements: reliability, high heat resistance and thermal shock resistance, good high temperature mechanical properties and so on. The nature of production, machine type, CNC machining program, the size and shape of the workpiece and the machining accuracy are factors tungsten carbide cutting tools materials processing.
