磨中心孔成形砂轮的修整,往往由于金刚笔的安装偏差,引起修整后砂轮形状的畸变,从而导致被磨中心孔形状精度的下降。本文目的是将金刚笔的安装偏差对磨中心孔成形砂轮修整的影响,作一分析,并在此基础上,提出一种提高成形砂轮修整精度的摆动修整方法。这种方法已在我厂生产的2M8015型中心孔磨床上采用,收效显著。 Grinding center hole forming wheel dressing, often due to the installation of diamond pen deviation, causing the distortion of the wheel shape after trimming, resulting in reduced center hole shape accuracy. The purpose of this paper is to analyze the influence of the mounting error of the diamond pen on the dressing of the grinding wheel centering hole, and on the basis of this analysis, a swinging dressing method is proposed to improve the finishing accuracy of the forming grinding wheel. This method has been used in our factory produced 2M8015-type center hole grinder, with remarkable results.
