Round bar cutter and blade cutter are very accurate tool. I plant the production of round bar knife, blade knife using parametric design, high precision CNC grinding machine for grinding, can be used for the user to process a suitable for different equipment, different specifications of the round bar and blade cutter. The alloy material after repeated tests, selection of hardness and bending strength of the data the most suitable materials, is not easy to wear and reduce the phenomenon. With high precision, durable, smooth surface and other products, and many other advantages. Since entering the market, the user feedback is good.
