With the development of the world economy, the improvement of people's living standard, natural stone (granite, marble ), jade, artificial stone, glass ceramics ( Advanced Micro, and cement products, has been widely applied in the building, the building decoration, used in the production of all kinds of decorations, daily necessities and application in road, bridge construction. Machining of these materials, are in need of various diamond tools.
Germany, Italy, Japan, South Korea production of diamond tools, variety, high quality, the price is very high. Their products are almost occupy most of the high-end stone processing market.
Nearly 10 years, Chinese manufacturer of diamond tools business development quickly. From the number of enterprises, the production of diamond tools business nearly 1000, year sales revenue exceeds tens of billions. Jiangsu city in Danyang Province, Hebei Province, Shijiazhuang City, Hubei Province, Ezhou city of Fujian province Quanzhou City, Guangdong Province Yunfu city as well as the head of Shandong province has nearly 100 diamond tools production enterprise. Chinese production of diamond tools business much, dimensions big, is of any other country in the world can be compared, will become the world's supply base for diamond tools. Some Chinese diamond tools varieties also have a high level of quality, some foreign diamond tools brand also commissioned by China's enterprises. However, most of the enterprises in the production of most products are of quality, low price of products. Although China's export of diamond tool number, the majority are low-priced products, known as the" garbage". Even the quality of product, its quality reached or exceeded the same products abroad, because it is made in China, also does not sell a good price, seriously affected China's image. The reasons for this situation is that? To sum up the main two reasons.
One is the low level of technology. Diamond tools production technology development can be divided into three stages. The first stage is used as matrix and diamond powder by mechanical mixing of the process for making diamond tools. This process is easy to generate component segregation; the sintering temperature is high, easy to cause the graphitization of diamond, reduce the strength of diamond. As a result of a variety of matrix material is mechanically coupled to, not fully alloying, matrix to diamond effect is poor, it is very hard to produce high-end products. The second stage is the pre alloyed powder as matrix and diamond mixture production process of diamond tools. This process as a matrix material to be fully alloying, low sintering temperature, does not reduce the strength of diamond, avoiding the composition segregation, the diamond to produce good embedding effect, so that the diamond function get very good play. Pre alloy powder for diamond tools matrix production, has high efficiency, slow attenuation characteristics, can produce high quality diamond tools. Third stage is the use of pre alloy powder for diamond matrix, using ordered arrangement ( multilayer, uniform diamond ) technology. This technology is accommodated by pre alloyed powder technology advantages, will be ordered so that each diamond, diamond was fully utilized, which overcomes the mechanical mixing process caused by the uneven distribution of diamond seriously affects the cutting properties of the defect, is the world's production of diamond tools of the new technologies.
The commonly used 350mm diamond cutting blade as an example, the first stage technique of cutting efficiency of 2.0m ( 100% ), a second stage technique of cutting efficiency of 3.6m ( up to 180% ), the third stage technique of cutting efficiency of 5.5m ( up to 275% ) and above. In China's current production of diamond tools business, 90% or using the first stage of the technology, less than 10% of the enterprises using second phase technique, individual enterprises using third stage technology. It is not difficult to see that the current Chinese diamond tools production enterprise, a few enterprise is fully capable of producing quality products. However, the vast majority of enterprises still use the traditional, backward technology.
Two is the malignant competition. Diamond tools are consumable items, market demand is big. According to the first phase of the current production of diamond tools of technology, new diamond tools business easier. In not too long a time, Chinese manufacturer of diamond tools business reached nearly a thousand. In common? 105mm diamond saw blade as an example, product grade for" quality", the factory price of 18 yuan, occupy about 10%; Product grades as the "standard", the ex-factory price of 12 yuan, occupy about 50%; Product grades for the" economy", the ex-factory price of 8 yuan, about accounted for 40%.
