When we saw the wood, there was often a pile of sawdust around. For an ordinary carpenter, the placement of sawdust is trivial, but if the electronics manufacturer cuts expensive materials such as silicon wafers, falling debris is a big problem for manufacturers. To this end, scientists at the Fraunhofer Institute in Germany used carbon nanotubes to create ultra-precise and thin saws, and also coated with a test diamond coat.
In general, diamond steel wire is often used to cut all kinds of expensive electronic materials, but the grooving of diamond steel wire will lead to the loss of part of the material or it can also be said to cause monetary losses. The saws made on carbon nanotubes and protected by artificial diamonds will be very sharp and thin, minimizing debris and minimizing material loss.
Scientists said that the manufacture of such saws is still a bit tricky at this stage, and the manufacturing process needs further improvement, but they believe that in the future such saws will be widely used.
