Tungsten market: domestic economic environment continued to slump, lack of tungsten market funds, business operations are not active, despite the current market is still more inquiry, but the actual volume was light, the buyer continued to actively keep the prices down, the seller cheap goods will go low, The two sides deadlocked, the high cost of tungsten concentrate the stock market, low-cost shipping that is facing a loss, so shipments will hold stocks lower part of even still working capital, the desire to purchase low-cost supply, in order to lower the average inventory cost, lower loss. Mainstream waste tungsten market remains steady sidelines, despite the weakening of the business mentality, but the price is not strong willingness mostly, of course, no shortage of cash-strapped businesses part of low-cost shipping, expected short-term will continue to play tug of war between two or more in price.

New high-speed adjustable tungsten carbide boring tool came up with a University of Technology, who designed and manufactured a new type of high-speed machining to adapt adjustable boring tool. Under normal circumstances, a double-edged effect for rough machining boring tools are good. Currently on the market supply of double-edged sword boring most of its structure is similar: that is equipped with two knife caught in the cutter body, by means of a cylindrical screws to fasten the serrated gripping surfaces. When the centrifugal force generated by the rotation head is received by the screws and the serrated surface of sufficient size, even when the changes of improper tightening, relying pressurized cylindrical surface of the locking screw, the holder purging phenomenon does not occur. But in fine boring, the situation is quite different kind. Larger adjustment range pole fine boring tools, when the ordinary structure, when the speed reaches 10000r/min. Significantly decreased its processing results. Especially in modern machining centers, when speed is greater than 6000r/min be more boring, prone to howling and flutter, affecting the accuracy and surface quality of the hole.

By experiment, it has been found that the imbalance is at the root tip of the above problems. The reason is so unbalance occurs arbor strain, presetting tooling holes out there is a big error in diameter and accuracy. For the amount of overhang of the tool is longer, the surface roughness Rz value to 3 ~ 6μm. To address this problem, responsible for development and testing to design a re-tune the pore size, from the structure of compensation can automatically feed the balance of the new high-speed adjustable tungsten carbide boring tool.

Mainstream waste tungsten market remains steady sidelines, despite the weakening of the business mentality, but the price is not strong willingness mostly, of course, no lack of tension in the business part of the funds cheap shipping. Expected in July and August, tungsten City or weaker overall market run, tungsten scrap prices also fell slightly possible.

Tungsten scrap market continues to hold steady on the sidelines. Currently waste tungsten drill mainstream transaction price excluding tax is still concentrated in the 188-190 yuan / kg, domestic waste tungsten blade 169-171 yuan / kg, imported blade 179-181 yuan / kg. 30-40 degrees grinding tungsten scrap material concentrated near the trading price of 1.6 yuan / kWh, 50-70 degrees concentrated in the vicinity of 1.76 yuan / kWh, more than 70 degrees centered around 1.85 yuan / kWh, but the individual businesses that 1.72 yuan / kWh you can receive 80 degrees sources.

Overseas tungsten City steadily. 23 evening MB ferrotungsten Rotterdam quote 41.5-42.5 U.S. dollars / kg tungsten, steady. Paratungstate Europe quoted 360-370 U.S. dollars / metric ton, steady, Hong Kong offer $ 361-370 / t degrees, low, dropping $ 4. As the European market into the summer break season, very weak overseas demand, the overall turnover deserted, expected short-term overseas tungsten City or continue weakening trend.

Tungsten market: recent domestic economic environment remains in the doldrums, tungsten downstream demand remained weak, tight liquidity market businesses generally. Tungsten concentrate prices almost bottomed out, buyers bargain Inquiry increased, but traders reluctant to sell, the actual turnover scarce, price is relatively stable, more tungsten scrap some traders stock market, worries about the market outlook began to increase, the proposed recent shipments may be appropriate, tungsten market is expected in summer or difficult to have a big breakthrough.
