The Difficulty of Processing Technology of the Large Size Steel Ball and Its Improvement Measures

目的:近几年伴随着科技的迅速发展,装备制造业对大型重载机械设备要求越来越高,对大型轴承钢球的产品质量和技术条件也提出了更高的要求。本文分析了大尺寸钢球的加工工艺难点及其改进措施。方法:作为关键性的轴承零件,对大尺寸钢球的质量要求进行不断的提高,对工具设计进行改进,大尺寸钢球的加工留量得以减少,对大尺寸钢球细、软磨的工序状态进行改善,提高钢球的加工质量。结果:改进后,钢球加工水平得以提高。结论:大尺寸钢球的加工工艺难点仍然是目前轴承制造厂中是急需予以解决的重难点技术之一。

Objective: In recent years, with the rapid development of science and technology, the demand of large heavy machinery and equipment in equipment manufacturing industry is higher and higher and it also put forward higher re-quest for the quality of large bearing steel ball products and technical conditions. This paper analyzes the processing difficulty of large size steel ball and its improvement measures. Methods: As a key bearing part, the quality require-ments of large size steel ball are constantly improved, and improved the tool design to reduce the machining allowance of large size steel ball, ameliorated the large size steel ball state of fine, soft grinding process to upgrade the quality of steel ball processing. Results: The level of the steel ball processing is improved. Conclusion: The difficulty of process-ing technology of large size steel ball is still urgently needed to solve, and it becomes one of the difficult points of technology in the bearing factory at present.
