Preparation method of ceramic hollow ball applied to ceramic CBN grinding wheel
A preparation method of a ceramic hollow ball applied to a ceramic CBN grinding wheel comprises the steps that carbon microspheres are evenly mixed with a resin type binding agent, evenly mixed with a ceramic binding agent, evenly mixed with an organic separant and sintered, the carbon microspheres, the resin type binding agent and the organic separant are carbonized in the sintering process, only the cured ceramic binding agent is left, and the ceramic hollow ball is obtained. The shape and size regularity of the carbon microspheres and the uniformity of a ceramic bond on the outer sides of the carbon microspheres have great influences on the quality of the ceramic hollow spheres obtained through sintering, and in order to improve the uniform mixing efficiency and reduce the deformation probability of the carbon microspheres, a uniform mixing mode of a planetary stirrer, internal circulation of a pressure container and fluid mixing is adopted from actual production. By selecting the size-stable carbon microspheres and the low-cost organic separant, the ceramic hollow spheres with stable quality can be prepared; the size stability and the breakage rate of the hollow sphere prepared through the method are better than those of products in the market, the roughness stability of the surface of a grinding wheel workpiece can be greatly improved, and the grinding wheel dressing frequency is effectively reduced.
一种应用于陶瓷CBN砂轮的陶瓷空心球制备方法，包括：碳微球与树脂型粘结剂的混匀、与陶瓷结合剂的混匀、与有机隔离剂的混匀、烧结，在烧结过程中碳微球、树脂型粘结剂、有机隔离剂均碳化，只留下固化后的陶瓷结合剂得到陶瓷空心球，碳微球本身形状及尺寸的规则度、碳微球外侧陶瓷结合剂的均匀度对烧结得到的陶瓷空心球质量影响重大，为了提高混匀效率、降低碳微球变形概率，本文从生产实际出发采用了行星式搅拌机、压力容器内循环、流体混合的混匀方式，通过尺寸稳定碳微球、低成本有机隔离剂的选用，可制备得到质量稳定的陶瓷空心球；通过本发明方法制备得到的空心球尺寸稳定性、破碎率均优于市面产品，可大大提高砂轮工件表面的粗糙度稳定性，有效降低砂轮修整频率。
