How to choose the right carbide grade

After selecting various types of alloys for different processed materials, the brand should also be selected according to the processing parameters. Generally speaking, the surface quality of the workpiece should be considered for finishing processing, that is, surface accuracy. During processing, the cutting speed is fast, the depth of cutting is small, the amount of cutting is small, the vibration is small, and the impact is small. It is required that the alloy has good wear resistance, high hardness, followed by strength and toughness, so the alloy with fine grain, high titanium content, and low cobalt content should be selected; The semi finishing wear resistance and strength toughness are moderate, and the alloy with medium particle tungsten carbide, medium Ti content and medium CO content is selected; Rough machining has large cutting depth, large cutting amount, slow cutting speed, large vibration and large impact, so it is emphasized that the impact resistance of the blade is better, followed by the wear resistance. Coarse grained tungsten carbide, alloys with low Ti content and high CO content should be selected.
