Tungsten Carbide Rod Surface Roughness

The roughness of tungsten carbide rod may to a certain extent affect the processing quality. There are four main factors that may affect its roughness.
1. Grain size of grinding wheel
The grinding of tungsten carbide rods is generally divided into two or three steps, the first several steps of which provide accurate grinding while the last step provides coarse grinding. The higher the granularity of grinding wheel is, the finer the emery particles are, and also, the texture will be finer and products will be brighter in the naked eyes.
2. Revolving speed of grinding wheel
The faster the grinding wheel revolves, the shorter the time it rubs with tungsten carbide rod, and naturally, the chance to cause textures in tungsten carbide rods will be smaller.
3. Concentration of grinding lubricant
Grinding lubricant is a kind of auxiliary material in the processing of tungsten carbide rod, but it will affect the roughness of tungsten carbide rod whether its concentration is too low or too high.
4. Grain size of tungsten carbide rod
Tungsten carbide rod is composed of many small and large particles. The finer the particles are, the smaller the gap between each other is and the better the compactness of products is. What is more, polishing process will also be easier.
In addition to the above factors, human factor is also very important. Only when operators are more careful and professional, will the tungsten carbide rods be better produced.
