摘要
将纳米复合材料技术应用于超高速陶瓷结合剂CBN砂轮试验研究,制备出力学性能和热学性能有明显改观的纳米陶瓷结合剂.与普通陶瓷CBN砂轮结合剂的实验结果相比,纳米陶瓷结合剂在耐火度、线膨胀系数、浸润性以及抗折强度上都有着显著优势,其砂轮贴片样条抗折强度达到了88.23 MPa,耐火度约为795℃.以此制备出的超高速纳米陶瓷结合剂CBN砂轮,不但安全性高,而且在对不锈钢、钛合金、高速钢几种难磨金属的干磨实验测试中也表现出了良好磨削性能.
The nanocomposite technology was applied to the experimental research of super high- speed vitrified bond CBN grinding wheel, and the nano-vitrified bond with markedly improved mechanical and thermal properties was developed. Compared with traditional grinding wheel vitrified bond, the nano-vitrified bond, possessing the strength of wheel section samples of about 88.23 MPa and refractoriness of 795 ~C, has significant advantages in the refractoriness, thermal expansion coefficient, invasion and bending strength. This super high-speed nano-vitrified bonded grinding wheel also showed excellent performance in the experiments of grinding several hard-to- grind materials such as stainless steel, titanium and high-speed steel.
