Details: Category: Tungsten's News; Published on Friday, 31 October 2014 18:56; Hits: 1039

Tungsten carbide turning tool is widely used in digital controlled lathes, which can perform both rough and finish machining. To ensure relatively large cutting depth, high feeding speed in rough machining, the turning tools used in rough machining are required to have high intensity and good durability. Finish machining focuses more on machining precision, so it asks for higher precision and good durability.

Tungsten carbide turning tools used in digital controlled lathes have to be of good consistency in durability so as to facilitate the management towards tool life. In the management of tool life, the cutter with lowest durability is taken as a basis for durability assessment. In this case, the consistency in durability is more essential than there average service life.

In order to meet the requirements of digital controlled lathes automatic processing, improve product quality and production efficiency and carbide turning tool of modularization and standardization should be applied firstly.

The Dangerous X-ray for Radiation Study

Details: Category: Tungsten's News; Published on Friday, 31 October 2014 17:07; Hits: 996

X-rays have earned a bad reputation as playthings. No distinction can be drawn between the danger of exposure to a high-powered X-ray machine and the fallout of an H-bomb. It is a danger that extends not only to the experimenter but to his potential progeny. Human evolution is the result of mutations caused by, among other agents, cosmic rays and the radiations of radioactive elements in the earth's crust. Any radiation added by man alters the rate of mutation, and is rightly a cause of deep concern.

Export has solved the problem of equipment cost. Protection against exposure to the rays is not difficult to arrange. With these two considerations out of the way, X-rays open a range of experiments equaled by few other phenomena of physics. In addition to providing a source of X-rays for radiographs, a generator of X-rays in combination with accessories enables you to measure the charge of the electron, to study the structure of crystals, to observe the wave-particle duality of matter and radiation, and to probe other microcosmic corners. During this process, tungsten alloy material will be a suitable material for radiation protection.
