The new cutting blade rules for the orderly distribution of the diamond blade, make the service life increased by 50% to 100%.
Reported that in 2003, scientists have in the experiment build a new type of carbon structure, but this finding has been controversial; most recently, two different research teams using different methods to confirm is called a body-centered tetragonal carbon is a three-dimensional network structure, that this structure with the 2003 found.
Introduction from the current domestic and foreign research situation, in the existing technical level is also difficult to achieve a diamond film of the article in large quantities, the industrialization preparation. And even small quantities of the preparation, there is also a long production cycle, the manufacturing cost is relatively high shortcomings.
