内容摘要:铸铁平板是用铸铁材料做成的平板。所用铸铁材料为细颗粒的灰口铸铁或合金铸铁。常见加工方法为刮制法,刮制的平板工作面能贮存润滑油和容纳微小灰屑在凹坑中,提高了基准体现的可靠性
铸铁平板,铸铁平台与岩石平板的主要区别是其制造所用材料和加工方法不同。
铸铁平板是用铸铁材料做成的平板。所用铸铁材料为细颗粒的灰口铸铁或合金铸铁。常见加工方法为刮制法,刮制的平板工作面能贮存润滑油和容纳微小灰屑在凹坑中,提高了基准体现的可靠性与稳定性。
岩石平板是用岩石材料做成的平板,所用岩石材料为具有精细颗粒、结构致密的花岗石、辉绿岩、辉长岩等自然界的坚硬岩石。加工方法是将毛石料进行锯切、打眼后,经多次研磨抛光至镜面光泽即成。岩石平板具有更耐磨、更稳定的性能。
