摘　　要：针对寿山石表面手工抛光效率低、质量较差等问题,分析5种寿山石的造岩矿物、显微硬度、矿物颗粒大小和致密度等参数,优选不同种类的磨料用拖拽抛光机来对其自动抛光。结果表明:拖拽抛光技术可自动抛光寿山石,寿山石抛光后的表面质量良好。对含较多石英、硬度较大、矿物致密度适中的寿山石,用核桃壳加金刚石的磨料抛光,其表面粗糙度Ra为293和335 nm;对含大量云母、硬度较低、矿物致密度较小的寿山石,用玉米芯加氧化铝的磨料抛光,其表面粗糙度Ra为521 nm;对造岩矿物纯粹、硬度居中、矿物最致密的寿山石,用玉米芯加金刚石的磨料抛光,其表面粗糙度Ra为235和186 nm。Aiming at the problems of low efficiency and poor quality of Shoushan stone surface manual polishing,the parameters of the rock forming minerals,the microhardness,the mineral particle sizes and densities of five kinds of Shoushan stones were analyzed,and the different kinds of abrasives were selected to automatically polish them with dragging-polishing machine.The results show that the dragging-polishing technology can automatically polish Shoushan stone,and the surface quality of the polished Shoushan stone is good.For Shoushan stones with more quartz,higher hardness,and moderate mineral density,which polish with walnut shell and diamond,its surface roughness Ra are 293 nm and 335 nm.For Shoushan stone,which contains a lot of mica,is low in hardness,and has a low mineral density,polished with corncob and alumina,its surface roughness Ra is 521 nm.For Shoushan stones with pure rock-forming minerals,medium hardness and densest minerals,which are polished with corncob and diamond,its surface roughness Ra are 235 and 186 nm.
