The International Association of Concrete Sawers and Drillers (IACDS) hosted its first ever seminar dedicated to concrete drilling and sawing at the recent Bauma Fair in Munich. The eight presentations - given simultaneously in English and German - went down very well with an audience of around 100 people, a far greater than the organisers had expected.
Since the early 1900’s chemists, physicists and industrialists have had a need for a material that was multifaceted. Diamond is one of those materials that can be beneficial in a wide range of applications such as jewelry, machinery and medicine. In the last five to seven years diamond has taken a new form. Its size has decreased from centimeters to millimeters to microns and now to nanometers. Nanometer sized diamond in low concentrations is invisible to the naked eye. In general, diamond can be found in two basic forms - monocrystalline and polycrystalline. This article by R. Abramshe focuses on the polycrystalline form of nanoscale diamonds.
US company, Western Saw, who this year celebrated its 80th anniversary as a manufacturer of diamond saw cores, carbide plate bodies and diamond core bits, recently initiated a redesign of its lightweight SpokeBack diamond core bit. The project was called Ultra. The scope of this project was to increase the stiffness and torsional load capabilities and further reduce the weight while maintaining the ability for the user to open the backend in case of a stuck bit. In addition, the company targeted a reduction in costs by decreasing manufacturing time, increasing material yield, and by eliminating drilling and tapping operations. Report by Anthony Baratta.
