引言从矿山采出的大理石、花岗石荒料到加工成建筑用装饰石板,一般要经过锯、磨、切三个工艺过程。而磨一般又包括粗磨、细磨和抛光等四、五道工序。粗磨是第一道磨加工工序,这道工序要求将石板基本磨平,为细磨、抛光创造条件。粗磨一般均采用较粗颗粒的磨料进行。目前我国石材锯割绝大部分采用砂锯,将砂锯加工时留在毛板上的锯痕磨平,一般要求粗磨的磨削量为1.5～2.5毫米左右,这样大的磨削量消耗的能量和占用的工时都很可
Introduction Mining from the marble, granite blocks to processing into building decorative stone, generally go through sawing, grinding, cutting three processes. The mill generally includes coarse grinding, fine grinding and polishing four or five processes. Rough grinding is the first grinding process, this process requires the basic flat grinding stone, fine grinding, polishing to create the conditions. Rough grinding are generally used coarse particles of abrasive. At present, most of China’s stone sawing using sand saws, the sand saw blade left in the processing of sawing marks on the mill grinding, the general requirements of coarse grinding grinding amount of 1.5 to 2.5 mm, so a large amount of grinding consumption The energy and working hours are very good
