British university drills world's smallest hole

Engineers and scientists at Cardiff University's Manufacturing Engineering Centre have found their way into new edition of Guinness World Records with a research breakthrough. The British university is listed under the entry for "smallest hole drilled."

 

As the records book explains, MEC scientists have developed machinery which can drill holes just 22 microns (0.022 millimeters) in width, less than half the width of a human hair. The new technique uses a process called electro-discharge machining and will eventually enable improvements in the miniaturization of electro-mechanical systems.

 

"Our ground-breaking research has appeared in publications all over the world, but Guinness World Records is a first for us," said MEC director professor Duc Truong Pham said. "We are delighted to feature in one of the best-read books on the planet."

 

The MEC scientists are now busy trying to beat their own record, using new nanotechnology equipment. These include a focused ion beam which can create holes of 100 nanometers (0.0001 millimeters), or about 1/800th the width of a human hair.

 

Guinness World Records, formerly the The Guinness Book of World Records, is the world’s best-selling copyright book. Published in more than 100 countries in 37 languages, its total sales exceed 100 million.
