为提高球头弹性磨具磨削M330钢材的加工效率和磨削效果,采用#600球头磨具进行磨削M330钢材实验.通过设计正交实验,研究了不同磨削参数时M330试样的表面形貌和材料去除机理,并得到了初步优化参数.通过单因素实验进一步优化了工艺参数.实验结果表明:增大球头磨具直径、供液速度及减小进给速度,均能降低表面粗糙度;磨削后试样表面粗糙度随设定磨削深度的增加先减小后增加;采用的高速供液法能显著降低试样表面粗糙度,有效改善球头磨具表面的切屑黏附现象;采用高速供液后,可在保证磨削质量的前提下提高进给速度;主轴转速越高,对应最佳供液速度越高.实验得出的不同主轴转速下对应的最佳供液速度为使用MOORE-450CPW连续轨迹坐标磨床进行的磨削加工提供了参照依据.
In order to improve the processing efficiency and grinding effect of Ball-end elastic abrasive grinding M330 steel, M330 steel was ground by # 600 ball mill.Through the orthogonal experiment design, the effect of different grinding parameters on M330 Surface morphology and material removal mechanism, and obtained the initial optimization parameters.The process parameters were further optimized by single factor experiments.The experimental results show that: to increase the diameter of the ball mill abrasive, feed rate and reduce the feed rate, can reduce Surface roughness; after grinding, the surface roughness of the sample first decreases and then increases with the increase of the set grinding depth; the high speed liquid supply method used can significantly reduce the surface roughness of the sample and effectively improve the chip surface of the ball mill Adhesion phenomenon; using high-speed liquid supply, grinding quality can be guaranteed in the premise to improve the feed rate; the higher the spindle speed, the higher corresponding to the optimum feed rate. Experimental results obtained at different spindle speeds corresponding to the best for Liquid speed for the use of MOORE-450CPW continuous locus grinding machine to provide the basis for grinding.
