This study investigated the sawing of A-plane and C-plane sapphires using the reciprocating diamond wire saw. The influences of process parameters and sapphire crystal structure on sawing force were experimentally researched. The experimental results indicated that, in sapphire sawing process, the sapphire crystal structure, the wire speed, and the feed rate had effects on the tangential sawing forces, and the tangential forces had good linear relationships with the material removal rates (MRRs). The specific sawing energies in the stable stage were clearly smaller than in the unstable stage.

Fixed diamond wire saw has the advantages such as higher cutting rate and clearer operating environment over the slurry wire saw in wafering. However, the higher cost and poor sliced wafer surface are still the obstacles for the diamond wire saw to totally replace slurry wire saw. In this study, the distribution of diamond grits on the wire was investigated by numerical simulation. The results show that there is a critical value of the abrasive interval to transfer the machining mechanism from plastic plowing to brittle indentation cracking for the material removal. The value depends on both the wire tension and bow angle during the operation.

Sawing Process

The endless diamond wire saw was developed using complex electroplating method. The sawing process on granite was experimented. The effects of diamond grain size, feed load, wire speed, and granite properties on sawing process were investigated. It is proved that the edges of sawing slot of granite were regulative and the cutting surfaces were smooth. The cutting efficiency could be improved by increasing the diamond grain size, wire speed, and feed load. However the increase of the feed load would induce higher tangential cutting force, and the case of the effect of wire speed was reversed.

Abstract A theoretical model of sawing granite by means of a diamond wire saw, composed of a multitude of diamond-impregnated beads mounted onto a steel rope, is presented. The wire sawing process has been contrasted with circular sawing with respect to diamond loading conditions. The analytical treatments have been supported by industrial quantitative assessments and qualitative observations. The evaluation of cutting forces as well as identification of system characteristics affecting wire vibration and wire rotation are instrumental in both machine design and tool formulation. This knowledge is also useful to diagnose and prevent problems inherent in diamond wire sawing of granite, such as the high incidence of wire breakage, unsatisfactory tool life and cutting capability, eccentric bead wear, etc.

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.
