本文根据加砂大锯的工作原理,阐明了其锯割过程是锯条、砂粒、石料三者之间相互摩擦磨损的过程,石料被切割的机理为磨粒磨损。在锯割过程中,锯、锯条、砂粒、石料组成石材加工工艺系统。影响系统性能的因素是很多的,有些是相互影响、甚至是相互制约的,为使系统在实际使用中能达到较好效果,本文根据磨粒磨损理论和切削理论,对其主要影响因素(锯条、砂粒)的材料选择、锯割时的切削力及锯割速度进行了初步分析。 In this paper, according to the working principle of large sand saw, it is clarified that the sawing process is the friction and wear between the saw blade, sand and stone. The mechanism of cutting the stone is abrasive wear. In the sawing process, saw, saw blade, sand, stone composition of stone processing system. There are many factors affecting the system performance, and some of them interact with each other and even restrict each other. In order to achieve good results in actual use, this paper, based on abrasive wear theory and cutting theory, , Sand) material selection, sawing cutting force and sawing speed for a preliminary analysis.
