Abstract: Diamond wire saw is the leading technology for use in cutting hard brittle material. Its smaller kerf and faster cutting time make it replacing the conventional slurry technology for those materials. Turned over the traditional router, this paper presents a novel approach that replaces the typical metallic core with a nonmetallic core, for manufacturing of ultraviolet curing resin fixed-abrasive diamond wire saw (DWS). The experiments show that the diamond wire saw made by this manufacturing method can obtain a good performance as well as taking many other advantages.

Abstract: The interfacial bonding strength between ultraviolet-curing resin and diamond is a key factor affecting tool properties in manufacturing of ultraviolet-curing wire saw. Therefore, in this paper, the application of surface-modified diamond coated metal was studied in ultraviolet-curing wire saw aim at retention problem of diamond in bond. Effects of surface-modified diamond were evaluated according to model of tensile test. Furthermore, retention mechanism of diamond was analyzed according to bond theory. The experimental results prove that the machining properties and service life of ultraviolet-curing wire saw can be improved by surface modification of diamond.

Abstract: This paper provides a novel process that can readily make abrasive tools bonded ultraviolet-curing resin. Excellent characteristics of ultraviolet-curing resin make it possible for bonding abrasive tools. Moreover, more applications demonstrate that ultraviolet-curing abrasive tools possess excellent properties without the shortcomings that are encountered in the case of the conventional resin bonded abrasive tools. Furthermore, various factors influencing the qualities of ultraviolet-curing abrasive tools are discussed.

Abstract: This paper describes a method for experimental development of a novel fixed abrasive nano-grinding plate (FAG-plate) which is proposed for lapping some rigid brittle materials, such as quartz crystal and silicon. The FAG plate is developed with ultraviolet-cured resin by rapid prototyping technology. The analysis shows that such FAG-plate can keep its grinding ability constant and continuous and it can make the roughness of machined surface reach to nanometer level. Based on experimental comparisons with conventional free abrasive slurry lapping plates, the lapping process using FAG-plate has several distinct advantages. One is that the machining efficiency is significantly improved. The second is that it improves the surface roughness of machined work-pieces, although it decreases the flatness tolerance of materials. Furthermore, the fixed abrasive nano-grinding plate is made by the new bonding materials- ultraviolet curing resin and thus the fabrication of FAG-plate is convenient and economical.
