When processing high-precision tungsten carbide products, the general processing technology is: rough turning blank → quenching and tempering treatment → fine turning → fine grinding → deburring → marking → inspection In the finishing process, tungsten carbide that requires very high precision Products are usually processed using CNC machine tools.
The machining method before the improvement was direct turning with a CNC turning tool. The motion trajectory of the turning tool was a straight line and the amount of feed remained unchanged. Using this direct processing method, the middle part is about 0.22mm larger than the two ends. In order to make the subsequent grinding allowance uniform and ensure the uniform force of the final grinding, so as to achieve the uniform roughness and high precision requirements of the shape and position tolerance of the final tungsten carbide product, necessary measures must be taken to avoid or reduce this phenomenon.
