In order to further improve productivity, various studies have focused on the improvement of stone processing technology and economy, in addition to improve output and reduce waste material cost, diamond manufacturers, machine tool manufacturers and tool manufacturers in order to increase the machine tool matching production capacity and has done a lot of research. One study found out at present marble processing machine production capacity reached the level. Europe is to use the highest efficiency of granite sawing machine efficiency is only equivalent to the marble processing to achieve the level of about 4%. Generally speaking, when the cutting depth is larger than 25mm, used for processing granite is unlikely, because it will lead to a lot of fever and diamond tool overload.
The diamond producers, diamond tool manufacturers, machine tool manufacturers, saw blade manufacturer and a research component of the European partnership of international organizations, began to study to the stone processing technology brings a new plan. Focus on the search for the way to solve the problem, as well as technical, economic and environmental evaluation, as well as the problem of approximating. The objective of this program is the development of processing subsystems, so as to meet the needs of intensive conditions, namely cutting depth ranges from 100 to 300mm. It includes a high performance of diamond saw blade, as well as the tool and the workpiece interface provides lubrication for improved system, in order to ensure that work well for a long time. Because this is a highly automated processing is the basic requirements. The research work carried out in two stages:
1, laboratory test, in order to get some basic information ( material property, cutting force, temperature and vibration ), as the machine tool and tool design should reach must improve the basic data.
Stone industry booming diamond contributed
In 2, the first phase of the data on the basis of tools and machine parts ( SAW agglomerates, lubrication and dressing system ) the development. In the first phase, the project design is one of the key using a small saw a simulation, in order to inspect the processing capacity, in the tool and workpiece interface ( grinding ) temperature, and the vibration properties. When using a small saw blade when, system characteristics and industrial application of the actual conditions of use and characteristics must be matched, this point is crucial. To meet this requirement, many authors have proposed a variety of cutting model, system in two main variables are recognized, namely, the cutting speed cutting depth ( Vc ) and ( AE ). Using these parameters and tool geometry information, can present a circular saw blade of the simplified model formula.
The use of this formula can reproduce industrial applications under normal circumstances similar conditions and force. Deep cutting condition of cutting temperature and cutting force measurement.
Using small laboratory deep cutting, so that the measurement in the cutting zone which generates heat and cutting force. This information to determine the production of large-scale sawing machine lubrication equipment and forecast of diamond tools in machining process may bear cutting force is a must. The use of high-strength diamond, its size is 30 / 40, particles per carat for 660 + 30. The first cutting the medium hardness of Italy granite, and then cutting the more difficult for processing of India red granite stone, which is one of the most difficult to cut materials. The sawing test, cutting depth is maintained for the 90mm, to adjust the feeding speed, so that in the most gentle cutting conditions are 100cm2 / min and 600cm2 / min in the worst condition change between. This condition can meet the industrial production set 380cm2 / min to 1000cm2 / min production efficiency. The temperature measurement results. As expected, with cutting efficiency the cutting temperature is also rising, but even at the highest speed, the cutting temperature is below 200 DEG c.. The use of dynamometer measurements in the processing of normal force and tangential force, for sawing machine design and size of the largest tool specifications development help. The analysis of cutting force and wear of diamond process inspection identified in the process range should be in that part of the. This is to keep the diamond uniform wear and adjust the diamond to finish cutting the desired exposure to highly critical.
Deep sawing granite processing requirements
In the first phase of information based on the determined, with deep sawing process related specialized design and processing equipment. Considering the diamond saw blade design, focus on examination of the following tools design requirements. Tool specifications and processing conditions must ensure that the material removal rate and the diamond exposure height matching is achieved when the grinding chip thickness. In deep sawing conditions differ from those of chip thickness is too small, the major areas of concern is that, if the cutting parameters are too large, then the chip thickness will be more than diamond exposure. In this case, because the diamond particles that exhibit excessive brittleness, will lead to the gap between the workpiece and the binder is insufficient, catastrophic failure. This will cause the normal force increases, causing the tool to catastrophic failure. Project plan on the other hand, is the focus of machine stability, lubricating power requirements, these would be the last deep sawing machine assembly to consider.
