Status Of Domestic Diamond Tools: Technology Limited Quality Time Lowest

With the development of world economy, people's living standards improve, the natural stone (granite, marble), jade stone artificial high (micro-ceramic, glass, and cement products, have been widely used in housing, building renovation, application in the production of a variety of decorations, household items and used in road, bridge-building. on the processing of these materials, require a variety of diamond tools.

    Germany, Italy, Japan, South Korea production of diamond tools in variety, high quality and high price. Their products are almost occupied most of the high-end stone processing market.

    Nearly over the coming year, China's production of diamond tools for enterprise development soon. The number of enterprises run from the production of diamond tools business nearly a thousand, the annual sales income of more than 10 billion. Danyang City, Jiangsu Province, Hebei Province, Shijiazhuang City, Hubei Province Ezhou City, Fujian Province, Quanzhou's head, Yunfu City, Guangdong Province and Shandong Province, has nearly 100 diamond tool manufacturers. China diamond tools in the enterprise as much as scale is any other country in the world can not be compared, will become the world's diamond tool supplier. Certain varieties of diamond tools in China have very high level of quality, diamond tools, some foreign brands also commissioned China's enterprises. However, the majority of production of most products are of quality time, low price products. Although China's exports of diamond tools are quite a few, mostly low-priced product, known as "junk." Even high-quality products meet or exceed the quality of similar products abroad, because it is in China, also can not afford to sell a good price, to seriously affect China's image. This situation is why? Summed up in two main reasons.

    First, low level of technology. The development of diamond tools production technology can be divided into three phases so far. The first stage is to use a single mass matrix powder for added mechanical mixing process of diamond production diamond tools. This process prone to component segregation; sintering temperature is high, likely to cause graphitization of diamond, reducing the strength of diamond. For various matrix materials to be mechanical, not fully alloyed matrix effect on the diamond package Xiang poor, difficult to produce high quality products. The second stage is the pre-alloy powder used for mixing matrix increases the process of diamond production diamond tools. Because this process is fully alloy matrix material, the sintering temperature is low, will not lower the diamond strength, to avoid component segregation, on the diamond package Xiang produce good results, so that function very well play a diamond. Matrix with a pre-alloy powder for the production of diamond tools, high efficiency, the characteristics of slow decay, can produce high quality diamond tools. The third stage is the use of pre-alloy powder as matrix, ordered arrangement of diamond with (multi-layer, uniform diamond) technology. This technology is up to the pre-alloy powder technical advantages, in turn ordered arrangement of diamond, so each piece had to full use of diamond overcome the mechanical mixing process caused by uneven distribution of diamond cutting performance of a serious defect affecting , is the world's production of diamond tools, the latest technology.

    Commonly used 350mm Diamond Cutting, for example, cutting the first stage of the technical efficiency of 2.0m (100%), the second phase of technology, cutting efficiency of 3.6m (up to 180%), the third stage of technology Cutting efficiency of 5.5m (up to 275%) above. China's current production of diamond tools in the enterprise, 90% or use the first stage of the technology, less than 10% of companies use the second stage of technology, individual use of the third stage technology companies. Not hard to see the current production of diamond tools in China enterprises, small businesses are fully capable of producing high quality products. However, the vast majority of companies still use traditional, backward technologies.

    The second is vicious competition. Diamond tools are consumables market demand. The first phase of production in accordance with the present technology of diamond tools, diamond tools of new businesses easier. In a short time, the production of diamond tools in China reached nearly one thousand enterprises. Commonly used? 105mm diamond blade, for example, product grade of "quality", ex-factory price of 18 yuan, and about 10%; product grade "standard", and prices about 12 yuan, or about 50% ; product grade of "economy", ex-factory price of around 8 yuan, or about 40%.

  These products in accordance with the average social cost, "quality" products, up to 30% margin, the "standard" products, profit margins can reach 5 to 10%, "economy" products can only be guaranteed as well, most of Enterprise prices are 8 yuan, and even low to 4 yuan. Since most enterprises are in the first stage of the technology level of product quality are similar to market share, had to fight the resources that price-cutting, chasing, to fight the more lower price. Such products are exported, no wonder people say that Chinese products are "junk." This is not to change, it is difficult to avoid trade friction. Meanwhile, the production of cheap products, enterprises still face the challenge of RMB appreciation.
