自公司2001年创立以来，基于当今国内外轴承行业最新研究和实践，为满足客户需求，公司自主研发了CBN立方氮化硼油石以及“HY”型系列超精油石，专用于自动超精机的一次超精和二次超精，能够有效提高轴承生产厂家的生产效率和轴承产品的质量水平。

Since the company was founded in 2001，according to today's domestic bearing industry research and application situation, and being draught by the actual demand, we have successfully developed a new series of CBN oil stone and“HY”type honing oil . These products were specially applied in the superfinishing machine' s primary honing and the final honing, andcan improve the production efficiency of the bearing manufacturers and the quality level of bearings products.

该型号产品适用于精密级微型轴承内外沟道的二次超精工艺（作精超用）常与HYCBN 5000或HYCBN9000配合用，强度高、耐磨、能明显改善轴承沟道表面粗糙度。
