Since 2002, the annual growth rate of 4 countries increased steadily, but not much. Noteworthy of Turkey, in 2002 the stone blocks production of 3.15 million t, by 2006 had soared to 9.4 million t, an increase of 2 times the output of the international rankings of stone, from Spain and Brazil in 2002 after the first row of 7, to 2006, more than Spain and Brazil and moved up to No. 5. More noteworthy, from 2004 to 2006 the world's major countries and regions exporting marble blocks and processed products output statistics, Turkey has been ranked first for 3 consecutive years, both were far ahead of output growth rate is also a major exporter in the original Italian marble. The reason, mainly in Turkey in recent years to strengthen the stone industry research, the university launched a marble cutting tools and technology research. Looking at the international stone market competition, product quality and competition from price competition, turn to shorten the delivery time competition. With the industrial technology development, international stone industry of stone sawing machinery, tools, technology has made great progress.







A stone sawing machinery







As we all know, from the blocks of stone mining and processing into a sheet and a variety of stone products are inseparable from the stone cutting machinery. The face of fierce competition in the international stone market, stone machinery manufacturers have to consider how to optimize their products to the market place. The current trend of stone sawing machine has the following aspects.







1.1 stone mining more widespread use of Diamond Wire Saw







Diamond Wire Saw achieve effective application of marble mining, the current other hard stone granite mining has also been made more and more applications. In addition to mining blocks, but also for cutting square blocks to reduce the transport volume and weight of blocks, but also provide for other machining length blocks.







1.2 Fixed Diamond Wire Saw Diamond Wire to a multi-channel development of computer numerical control







Most large stone processing enterprises are increasingly using computer numerical Diamond Wire Saw sawing stone blocks into the plate or special specifications of stone products. But different thickness of sheet metal cutting can be easily adjusted to be equipped with space agencies Diamond Wire Saw, which requires a larger investment. The most economical way to stone product range under the same time with Diamond Wire Saw, Frame Saw Saw Blade Saw, with the use of the three, mutually reinforcing.







1.3 The multi-purpose development to bridge sawing machine







No matter what kind of stone products production, important equipment indispensable bridge sawing machine. New bridge sawing machine not only has the versatility and use of computer control to full automation, personal computers can be programmed office, but also can be connected to an external computer-aided design procedures, all have one set to complete the processing operation.







Traditional bridge sawing machine, saw blade shaft fixed in one direction, the workpiece is placed on the table can be rotated. Now more and more manufacturers are no longer using the rotary table program, which can change the cutting position with the blade drive mechanism. The advantage of not turning the weight of a large table, but also improve the cutting accuracy.







Many manufacturers also developed using a variety of processing tools bridge sawing machine can be used along with forming tools, drilling tools, to achieve a machine.







1.4 stone processing center







The so-called processing center that can be done in several consecutive multistep process automatic CNC machining.







Stone steles the international market, decorative stone products for building fierce price competition continued to shorten delivery time, and further promote the Italian decorative stone cutting, polishing machinery, and export processing center. Mainly two types of machinery, that is five-coordinate coordinate shaft shaft cutting machine, which in addition to X, Y, Z axis, there are a rotation axis C, tool rotating around a vertical axis, and A tool axis can tilt any angle, ease of processing tombstone slant.







With the development of stone machinery control systems, mechanical structures, also tends to be more perfect. For example, adjustable height vacuum sector can be excluded from sawdust without impact to the bottom of the follow-up procedures for the. In addition, the processing tool spindle or table surface can automatically tilt the coolant line of people with the saw dust collection solution set.







Most multi-function CNC machining center, the skills of operators have become increasingly demanding. To this end, a number of stone machinery manufacturers have developed easy to use personal computer-controlled operating system, to minimize the auxiliary operating time. In short, the development trend of the entire production line automation.







Stone panel is currently making products such as kitchen, great market demand. Such processing often requires the control panel to install the pool and cutting out the stove and other setting in, its processing, including some of the standard processes and special processes. To this end, there are stone machinery manufacturers will automatically control the bridge sawing machine and processing center panel together to form kitchen products such as automated production lines.







Special machinery parts processing stereo 1.5







The bridge sawing machine with a number of automated processes between the superiority of the combination of CNC machine tools to make table from all directions into the processing location, and the large diameter circular saw blades, the transmission frame can be rotated to different directions, and equipped with the tools positions automatically switch to a different processing tools, X, Y, Z axis coordinates assembly of the appropriate size guide to a variety of three-dimensional shape of the workpiece processing.

stone processing tools





Stone Processing, sawing machine grinding, polishing and other processing machinery innovation, be equipped with various types of diamond tools. Requirements of current trends and long life of diamond tools work, work fast, small vibration and low noise. The most commonly used stone industry and the largest amount of diamond saw blade Diamond Wire. Performance in recent years, these two tools have been improved.







Diamond Saw Blade

2.1





The opening of diamond saw blades diamond protrusion can be made as soon as possible into the normal and efficient working condition. To shorten this process, new diamond blade diamond saw blade structural design and more to do to improve.







Appear before the diamond saw blade made a step or square cross section tapered to reduce wear on both sides of head, lower power consumption and helps reduce vibration and noise. Conical section head at the top level generally higher than the bottom width of the small width of about 2mm. This type of cutting blade of a state that has entered the high-speed cutting performance.







Streamlined blades made of diamond saw blade rotation arc-shaped front-end, cutting resistance can be reduced and reduce the cyclical impact load. Heads on both sides of the groove system that can reduce the number of channel heads friction streamline and improve the cooling effect, but also more conducive to sawdust discharge, thus improving cutting performance.







In addition, the diamond segment sintered materials can be changed using the new binder matrix performance heads, so that a broad spectrum of cutting performance of diamond blade for cutting a variety of different soft and hard stone.







2.2 Diamond Wire







Practice shows that geometry can affect Diamond Diamond Wire sawing performance. Currently there is a new double convex ring Diamond, injection molding techniques using diamond Diamond cylinder made out of two convex ring. The new Diamond Wire Diamond Wire, compared with the traditional, can increase the cutting speed and reduce the cutting costs, but slightly reduced service life. Important injection molding techniques using diamond can create other more complex shapes Diamond, to comprehensively improve the performance of Diamond Wire Saw offers the possibility. Change the shape of the current Diamond Cutting Diamond Wire improve the performance of key technologies.







Diamond Wire of life factors in addition to diamond quality, diamond bead matrix composition, ratio and sintering process, the saw dust and erosion is also an important factor in the cooling liquid. To prevent the saw dust and the cooling fluid on the beaded rope abrasion, technical measures are being taken plastics, ie, the beaded appearance of bread and apply a thin rope of rubber like flexible material, bonded fixed intervals Diamond, the Diamond mode between Note a flexible wear-resistant material such as rubber or resin material to form the interval between the sets of beads to replace the steel coil spring spacer sleeves. The plastics processing will be Diamond and Diamond rope and metal and between the interval of rigid contact between the sets to soft contacts, and enhance the overall flexibility of the Diamond Wire, Diamond Wire reduce the bending stress, thereby enhancing the use of life. Diamond also improved the forces on the diamond, reducing fragmentation and loss of diamond to improve sawing efficiency.







3 stone sawing process







Broken rock single diamond experimental results show that diamond working speeds of up to 40m / s or more. Thus, the current use of various diamond tools for stone industry are far from its full potential performance. International Stone Processing and import and export trade has always been the bulk products, marble granite, marble and granite sawing process and therefore has been much research attention. Moreover, stone sawing process also involves lower production costs, efficient use of stone resources.







3.1 Process of sawing marble







Application of Diamond Wire sawing marble more than 20 years, it is best to study the working conditions and effective cutting parameters, Turkey Hacattepe University to design a new experimental Diamond Wire Saw, the use of sensors automatically detect the cutting process parameters, and automatic computer program with the measured data storage and analysis.







Diamond Wire Saw the best of working conditions should first analyze the factors affect the efficiency of saw blade, and some factors are not controllable, some controllable. The former includes cutting stone by nature, such as hardness, strength, homogeneity, contained in the mineral composition and structural characteristics and so on. The latter include the power saw, sawing method (horizontal or vertical), cutting speed, cut into the corner and saw the angle, Diamond Wire structures technical performance, operator skills. On multivariate statistical analysis of these factors, changes in controllable factors in response to uncontrollable factors can get best work Diamond Wire to improve cutting efficiency and reduce the cutting cost. Equipped with sensors using the automatic computer program experimental Diamond Wire Saw for cutting different types of marble, the best experimental determination of cutting conditions can be established between the marble can be cut grading system, but can also identify different types of Diamond Structure Cutting Performance.







3.2 Process of granite sawing







As the international stone market competition, particularly large granite plate external wall finishes for high-rise buildings, the technical requirements to be a strict, far from the drilling and blasting method can satisfy the blocks of granite mined. To this end, the use of exploitation of Diamond Wire sawing of granite blocks and granite plate technology of industrial countries is bound to be the stone seriously. The study includes extraction rate of finished blocks to improve the quality of blocks and reduce the cutting costs, promote accurate and no breakage of the cutting process to minimize the loss of stone resources, the ecological damage to the environment.







Diamond Wire Sawing of granite practice, direct factor affecting the cutting performance of cutting parameters, the main Diamond Wire speed, cutting speed saw one angle. There is also a factor can not be ignored for Diamond Wire bending, due to increased edge effects tend to wear Diamond Wire.
