Surface quality of engineering ceramics honing
Honing is often used for finishing the inner hole surface. It is also an efficient processing method that can remove large margins and is suitable for processing precision parts with high relative motion accuracy. With the application of superhard abrasives such as diamond, honing processing of high-performance ceramic materials will account for a large proportion in the future. Honing processing is the best choice for machining of hole parts such as ceramic engine cylinders (Mg-PSZ, TZP), ceramic sediment pump cylinders (ZTM, Al2O3) and ceramic bearing sleeves (HPSN, RBSN).
Different types of ceramic materials have different grinding surface roughness values. The surface roughness value of the processed ceramic materials reflects the grinding processability of the material to a certain extent. The honing processing of ceramic materials has the same rules. The influencing factors on the surface quality of honing processing of engineering ceramic materials can be divided into two categories: honing process parameters and honing tool parameters. Among them, the influence of tool parameters is the most significant. The particle size of diamond oil has an important influence on the surface roughness of ceramic materials after honing. In the actual processing of engineering ceramic parts, resin-bonded diamond tool products are generally used as cutting tools. In order to obtain higher grinding ratio and processing efficiency, metal-bonded diamond tools are usually used.
For precision parts with matching accuracy requirements, the final processed surface quality is even more important during use. Taking the application of ceramic materials in automobiles and motorcycle engine blocks as an example, if the surface quality of the material is poor, surface wear will occur: sharp convex peaks on the surface of the ceramic material or cutting of metal parts to match, or surface profile peaks between ceramic materials collide with each other, eventually causing the fitting dimensions of the parts to exceed the tolerance range, and the fitting accuracy to decrease, thus increasing fuel consumption.
Different types of ceramic materials have certain differences in surface roughness values ??during honing. The lower the strength and higher the brittleness of the ceramic material, the greater the surface roughness value of its processing. The honing processing of ceramic materials should also consider the influencing factors of the material.
Types of ceramic materials is different, the honing processing surface roughness values exist certain differences. The strength of the ceramic material is lower, the higher the brittleness, the processing surface roughness values. Ceramic material of honing processing and the influence factors of materials should also be considered.

Among the three honing tool parameters of diamond oil stone particle size, concentration and binder, the effect of oil stone particle size and oil stone binder on the surface roughness of ceramic material honing is more significant.
Diamond abrasive grain size, concentration and binder in the three parameters of honing tools, abrasive particle size and abrasive binder for ceramic materials honing processing has obvious effect of surface roughness.

Engineering ceramic materials adopt a flat-top honing processing method, which can remove sharp convex peaks in the surface profile of the material and form a ceramic material surface with flat-top characteristics, thus avoiding wear of mating surface materials in practical applications.
Engineering ceramic materials with flat-roofed honing processing method, can remove material surface contour sharp convex peak, in the form with flat top properties of the surface of the ceramic material, avoid mating surface materials in the practical application of wear and tear.
