Primary ultra-fine oilstone with gradient particle size distribution and preparation method of primary ultra-fine oilstone
The invention discloses a preparation method of primary ultra-fine oilstone with gradient particle size distribution. The method comprises the following steps: 1, mixing and grinding a high-temperature ceramic bond and a low-temperature ceramic bond to obtain ceramic bond powder; 2, dripping polyacrylamide-ammonia water into deionized water to be subjected to ball milling with the ceramic bond powder to obtain slurry, then adding a grinding material and a ceramic pore-forming agent, and stirring the mixture evenly and left to stand to obtain a rectangular green body ; 3, drying the rectangular green body step by step; 4, heating and preserving heat to obtain a sintered green body; and 5, performing wax permeation, cutting and grinding to obtain primary ultra-fine oilstone. The invention also provides the primary ultra-fine oilstone with gradient particle size distribution. By controlling the particle sizes of the ceramic bond and the grinding materials, the grinding materials are stacked layer by layer according to the sequence of the particle sizes from small to large, and the primary ultra-fine oilstone with the abrasive particle sizes in gradient distribution is obtained; and according to the ultra-fine oilstone, one-time ultra-fine machining is achieved during ultra-fine machining of a bearing raceway (or a groove), and the machining efficiency is improved.
本发明公开了一种粒径梯度分布的一次超精油石的制备方法，该方法包括：一、选用高温陶瓷结合剂与低温陶瓷结合剂混合研磨得到陶瓷结合剂粉体；二、将聚丙烯酰胺‑氨水滴入去离子水中与陶瓷结合剂粉体球磨得到浆料，再加入磨料和陶瓷成孔剂搅匀并静置得到长方形坯体；三、将长方形坯体分步干燥；四、加热保温得到烧结坯体；五、经渗蜡、切割和打磨得到一次超精油石；本发明还提供了一种粒径梯度分布的一次超精油石。本发明通过控制陶瓷结合剂与磨料的粒径，使得磨料按照粒度从小到大的顺序逐层堆积，得到磨粒粒度呈梯度分布的一次超精油石；本发明超精油石在轴承滚道(或沟道)超精加工时实现了一次性的超精加工，提高加工效率。
