The diamond rope saw is a new technologyabroad for the mining and cutting of stone. Its advantagescover high resource usage,high quality of quarry-stone,wide adaptability,high efficiency of mining,low cost,nosound and no other pollutions,simple operation,conve-nient use and low intensity of labour.SJ-89 diamond ropesaw developed by Changchun College of Geology has agood property.
In the last years wire sawing processes have been invented for a lot of applications in the field of natural stone and construction materials especially at very thick materials or difficult to access components.In the late 80′s,few companies begun metal cutting with diamond wire cutting systems with moderate success.The diamond wire cutting was limited to small carbon steel shapes,such as pipelines for transporting gas or oil under sea.Especially the task of cutting pure steel components offers new fields...
In this paper,sawing trajectory and mechanism of diamond wire saw are theoretically analyzed.Sawing experiments of marble and granite are carried out to verify the results of the theoretical analysis.Conclusions drawn from the investigations are as follows:(1)Sawing trajectory of diamond wire saw is approximately an involute of circle.Wire tension and the force exerted on stone by unit length of wire during sawing determine the shape of the involute.(2)Linear wire speed is so high and the pressure exerted o...
