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.

Abstract: In recent work, a creative idea has been proposed by applying the rapid prototyping technology to develop a new diamond-coated blade based on ultraviolet-cured resin bond. The new technology features many advantages such as fast processing speed, low environmental pollution, and low energy consuming. This paper makes an investigation on the adherence and abrasion mechanisms of such diamond blades. The experimental plan is well designed for selection of an optimal prescription of the mixture to achieve good mechanical performance and a manufacturing process is proposed to produce ultraviolet-cured resin bonded diamond coated blades. Practical experiments are carried to test the blade performance and to compare with different tools in incising artificial crystal. Furthermore, this paper also observes how the tensile strength and elastic modulus of ultraviolet-cured resin affect the crevasse and quality of machined edge surfaces.
