摘要
硬度62HRC的球面轴瓦要进行断续切削加工,球面轴瓦的加工精度要求高,加工难度大。解决断续切削过程中的振动和让刀是保证断续切削加工精度的关键,通过采用对称加工法,同时采取调整加工程序和增强加工系统刚度的措施可有效解决精密超硬球面轴瓦断续切削的精度问题。在实际生产中,调整加工程序并配合对称加工法得到了有效的应用,这种加工方式是保证断续加工精度及精度稳定性的有效途径。精密超硬球面轴瓦的断续切削加工研究对于有高精度和高硬度要求的断续切削加工有一定的参考和借鉴意义。
The spherical bearing with hardness 62 HRC should be discontinuous machined. The machining precision of spherical bearing is required to be high and the machining difficulty is great. The key to ensure the accuracy of interrupted cutting is to solve the vibration and the cutting tool in the process of interrupted cutting. By adopting the method of symmetry machining,adjusting the machining program and enhancing the rigidity of the machining system,the problem of precision of the discontinuous cutting of the ultra-hard spherical bearing bush can be effectively solved. Adjusting the machining program and symmetric machining method have been effectively applied in actual production,which is an effective way to ensure the accuracy and stability of intermittent machining. The study on the discontinuous cutting of precision ultra-hard spherical bearing bush has certain reference significance for the discontinuous cutting with high precision and high hardness.
