无心磨床磨削工步次数对棱面度的影响

Influence of Grinding WorkingStep Frequency of Centerless Grinding Machine on PrismaticRoundness

无心磨床磨削工步次数对棱面度影响的试验表明，增加粗磨遍数，可较好地改善外圆表面棱面度；细磨遍数的增加对棱面度的改善不明显。该试验不仅验证了成圆理论，而且对磨加工工步次数对棱面度的影响有一个定量的认识，从而有利于磨加工质量的提高。附表３ 个。

Test of the influence of grinding working step frequency of centerless grinding machine on prismatic roundness showed that increasing number of times of rough grinding may improve prismatic roundness of outer diameter to a greater degree; increasing number of times of precision grinding has no obvious influence on improvement of prismatic roundness. This test not only verify circle forming theory, but also make one to gain a quantitative understanding about influence of grinding working step frequency on prismatic roundness so as to be of advantage to raise grinding quality.
