Without the magnetic properties of granite, is widely used in production of precision measuring tools and instruments and the base platform

With the precision and ultra- precision processing technology, with high hardness, high wear resistance , low thermal expansion coefficient , are not electrically conductive , non- magnetic properties of granite, is widely used in production of  abrasive grinding  and instrument platform and the base , ultra- precision machine tool bed and rails , spindle, spindle box and workbench. The traditional processing methods granite widespread low processing efficiency and quality problems . Belt grinding is developed in the sixties and advanced machining methods. It has a high processing efficiency , " cold " grinding , grinding speed and stability,  abrasive wheels  , grinding and low cost , in the machinery manufacturing plays an increasingly important role , is now widely used in ordinary metals , difficult to machine metals plane , inside and outside the circle , the processing of complex shaped surfaces . Abroad in granite, marble, ceramic , glass and other  abrasive grinding  materials aspects of belt grinding process carried out some exploratory research . In this paper, abrasive belt grinding technology in the hard stone processing applications were reviewed . Belt grinding characteristics compared with the ordinary grinding wheel , abrasive belt grinding has the following salient features.
