摘要

摘要: 针对金刚石薄圆锯片基体磨削表面质量控制问题，在数控卧轴圆台平面磨床上开展圆锯片基体磨削正交试验，研究磨削工艺参数对其端跳、平面度、同片厚度差的影响规律。结果表明：砂轮转速对端跳影响最显著，提高砂轮转速有利于减小端跳；工作台转速对平面度以及同片厚度差影响最显著，提高工作台转速有利于获得平整和光洁的表面。优化的磨削工艺参数组合是砂轮转速为1 500 r/min，进给速度为3 000 mm/min，工作台转速为250 r/min，磁力为90%。在此参数下，对金刚石圆锯片基体进行磨削，其磨后的端跳、平面度和同片厚度差分别为0.08、0.02和0.004 mm，远小于标准规定的0.12、0.08和0.020 mm，且无明显磨削损伤缺陷。

Abstract: Aiming at the surface quality control of diamond thin circular saw blade substrate grinding, the orthogonal experiment of circular saw blade substrate grinding was carried out on the NC horizontal axis circular table surface grinder.The effects of grinding process parameters on the end jump, the flatness and the thickness difference of the same blade were studied.The results show that the rotation speed of the grinding wheel has the most significant effect on the end jump.Increasing the rotation speed of the grinding wheel is beneficial to reduce the end jump.The rotation speed of the worktable has the most significant effect on the flatness and the thickness difference of the same blade.Increasing the rotation speed of the worktable is beneficial to obtain a smooth and clean surface.The optimized grinding process parameter combination is that the grinding wheel speed is 1 500 r/min, the feed speed is 3 000 mm/min, the worktable speed is 250 r/min and the magnetic force is 90%.After grinding the matrix of diamond circular saw blade under this parameters, the end jump, the flatness and the thickness difference of the same blade after grinding are 0.08, 0.02 and 0.004 mm respectively, which are far less than 0.12, 0.08 and 0.020 mm specified in the standard, and there are no obvious grinding damage defects.
