Abstract: With the growing use of natural stone both in industrial field and in ornamental materials of building, Complex-shaped stone products are being dramatic increasing. It is necessary to machine it with flexible and automatic machines such as NC machining enters. Versatile tools such as shaped diamond mills are used. The wear mechanism of diamond mills in stone cutting is presented in this paper though experiments. The macro-geometries of diamond mills such as mill diameter, profile and weight are described. The changes of macro-geometries of shaped diamond mills can be used to express tool wears. The changes can therefore be used to forecast tool wears in stone machining.

Abstract: The diamond wire-saw is a kind of stone machining equipment with flexible cutters. It is widely used in quarrying granite, machining of quarry stones and various special-shaped stones. Experiment has been carried out on the parametric relations among wear form, cutting liner speed and tightening force of diamond wire according to the experimental result of diamond wire-saw in quarrying Shidao Red granite with high efficiency. The suitable working parameters of diamond wire-saw in granite cutting are discussed in the paper, the purpose of which is to improve productivity and quality, and to reduce the cost of the diamond wire-saw as well as to make good use of advantages of diamond wire-saws. Practice proves that diamond wire-saw is an ideal equipment with high economy index in quarrying granite.
