金刚石串珠锯在花岗石高效回采中的应用研究

金刚石串珠锯是使用柔性刀具加工石材制品的设备．广泛应用于石材回采、荒料整形、板材及各种石材异型制品加工。本文结合金刚石串珠锯在石岛红花岗石高效回采中的应用实验研究，对串珠锯的磨损形式和锯切线速度、串珠绳预紧力等工作参数之间的关系进行了实验研究，探讨了金刚石串珠锯回采花岗石的合理工作参数，以提高金刚石串珠锯的生产效率，降低使用成本．以充分发挥金刚石串珠锯的优势。实践证明，金刚石串珠锯是一种理想的、综合经济指标很高的花岗石回采设备。

APPLICATION RESEARCH OF DIAMOND WIRE-SAW IN HIGH EFFICIENCY QUARRYING OF GRANITE

The diamond wire-saw is a kind of stone machining equipment with flexible cutters. It is widely used in stone quarrying, machining of blocks and various special-shaped stones. Experiment was 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 high efficiency quarrying of Shidao Red granite. The suitable working parameters of diamond wire-saw in granite cutting is discussed in the paper, the purpose of which is to improve the 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 the quarrying of granite.
