Experimental Research on Surface Grinding of Industrial Ceramics

Industrial ceramics is a new type of industrial material developed in the last two or three decades. It is the product of new technological revolution with information science, materials science and biological science as the frontier. This material has been highly valued by people and has been widely used in modern industry and science and technology. Industrial ceramics are extremely hard. It has good heat resistance, thermal stability and heat insulation, and has strong anti-oxidation ability at high temperature. But its brittleness is also great. The high hardness and brittleness of industrial ceramics make their machining process quite difficult. For most occasions, the accuracy and surface quality requirements of ceramic parts are very high and only precise machining could meet the requirements. Among all the processing methods, the most efficient processing method is grinding with diamond grinding wheels. The 1A1 diamond wheel can be used for surface grinding of industrial ceramics.

As the depth of cutting increases, both the normal component and the tangential component increase. Another parameter that affects the grinding force is the workpiece speed. As the workpiece speed increases, the volume of material removed per unit time increases. When other conditions are constant, the cutting thickness of single abrasive grain increases, which also leads to an increase of the grinding force. During surface grinding process of industrial ceramics, the grinding force rate has little effect on the grinding parameters, and there is no obvious change trend. This means that the grinding force rate is independent of the grinding parameters and it’s only related to the material being ground, the characteristics of the grinding wheel and the grinding method. This feature is the same as that of ordinary carbon steel. However, compared with ordinary carbon steel, the grinding force ratio of industrial ceramics is much larger, generally above 3.5. Ordinary carbon steel has a grinding force ratio of only 1.8-2.5, which indicates that industrial ceramics are harder to be ground than ordinary carbon steel.

Industrial ceramics are difficult to be ground. They can be ground with diamond grinding wheels when the cutting depth is small. Since industrial ceramics can only be ground at a small depth of cut, the grinding force is not large.
