It is a currently dominant method to use wire saws for cutting silicon material because of its production efficiency and energy efficiency. Diamond wire saws, or fixed abrasive wire saws, have attracted much attention to researchers and engineers due to many advantages, including high cutting efficiency and low environmental pollution. This paper develops a novel diamond wire saw using ultraviolet curing technology. High-strength piano wires and polyethylene wires are selected as wire cores, and photosensitive resin is used as the binder. The problem of wire saw strength is mathematically formulated, and the effective parameters are analyzed. The surface morphology is analyzed for the developed diamond wire saw. A series of cutting experiments with different saws of varying manufacturing parameters are carried out. The slicing performance of such diamond wire saws is evaluated and compared. The experimental results show that the developed saw using the photosensitive resin has a very good performance in slicing silicon ingots. By the comparison between the developed diamond wire saw and the electroplated diamond wire saw, the surface smoothness of the workpiece is better than that by the latter.

Fixed Abrasive

Fixed-abrasive diamond wire saw is widely used for slicing semiconductor materials. In this paper, a novel manufacturing method is studied by using polyethylene wire to replace the traditional metallic core wire. A new coating device of ultraviolet-curing for rapidly making diamond wire saw is developed. In terms of tensile strength experiments’ results, a high strength polyethylene multi-strand wire is finally selected as the core wire of the fixed-abrasive wire saws. Experimental results show that the high tensile strength of polyethylene multi-strand wire can satisfy the technical requirements of fixed-abrasive wire saws.

Fixed Abrasive

Wire saw, with its ability to cut hard brittle material, such as silicon ingots, crystals and quartz, has emerged as a leading technology for production in semiconductor and photovoltaic industry. There are some defects in conventional loose abrasive wire saw such as significant industrial waste, low machining efficiency, high running costs, etc. As a countermeasure to these problems, some fixed-abrasive diamond wire saws are produced by electroplating process, bonding with resin agent or mechanical embedding of abrasive grains into piano wires. Nevertheless, there still exist disadvantages such as low efficiency of bonding process and high manufacture cost. For this reason, in the research, an idea of making fixed-abrasive diamond wire saw bonded with ultraviolet-curing resin is proposed. In manufacture process, generally, the preparation of materials, improvement of adhesion, and the art of ultraviolet curing determine what technologies is most effective. Therefore, to attain a specific set of properties in the cured wire saw and to achieve an efficient ultraviolet-curing process, the factors that influence the photopolymerization should be well understood. In this paper, the manufacturing process of an ultraviolet-curing resin wire saw is illustrated. Moreover, slicing experiments are deduced to evaluate the results of the study.

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.

Operational Aspects

Nowadays, most mining and quarrying industries utilize a diamond wire saw machine for bench cutting operations. This method uses a metal wire or cable assembled by diamond beads to cut the hard stone into large blocks. Many parameters classified into controllable and uncontrollable parameters affect the performance of the diamond wire saw cutting method. The uncontrollable parameters are related to rock engineering properties, and controllable parameters are related to operational aspects and machine performance. The diamond wire sawing process’s production rate is one of the most critical parameters influencing the design optimization and quarrying cost estimation. The cutting rate and wear rate of diamond beads are the most important factors to evaluate quarries’ production performance. This study aims to determine the effects of different controllable and uncontrollable parameters on different quarries’ production rates. Rock engineering properties like strength, hardness, and abrasivity, and operational aspects, such as cutting angle and drive wheel diameters, are considered as the main factors affecting the production performance of the diamond wire saw method. To discover the influence of these parameters, a detailed investigation in ten quarry operations was carried out. The relation between cutting rate and diamond bead wear with different parameters is estimated. It was observed that different controllable and uncontrollable parameters could increase or decrease the cutting rate and diamond bead wearing. Furthermore, using simple and multiple regression analysis, performance prediction of the cutting rate and wearing of diamond beads was developed, and the best equations were proposed.
