In this research, grey relational analysis (GRA) is applied to prevent an ill-conditioned wire saw machine from producing an unconfirmed product that is screened from the synchronously occurring multiple quality characteristics.
Since the minimum chevron notch width is limited by the size of the cutting wheels or wire saw used to produce it, as the sample size gets small enough, the notch width becomes large in relation to the sample size.

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 recent years,ultrahard materials such as diamond and CBN have been developed rapidly and used widely due to its unique properties.The production,assortments,applications and developing features of diamond,CBN and their tools are briefly introduced in this paper.The future development in diamond and CBN including R&D of new ultrahard materials,such as diamond like carbon and B-C-N system compounds,low noise diamond disc and wire saws worth notice in development of diamond tools,processing industries to...
On the basis of our practice and investigation, some effective measures to further improve the quality of diamond tool are discussed. First of all, good performanced, coarse crystal, thermally stable, ultrahigh grade diamonds are needed. In order to improve the diamond retention in the bonds, it is suggested to add carbide former element metal in bond or use coated diamond. Ultra fine metal powder and pre alloyed metal are suggested to use in the matrix for better bond performance. Process of powder granu...
