The week after CemeCon Inc. held a ribbon-cutting Jan. 17 to officially open its new 15,000-sq.-ft. headquarters and CVD diamond coating facility, I spoke with Gary Lake, company president, to discuss the expansion and developments in cutting tool coating technology. The opening marks the fourth expansion of production capabilities since the company, which is a subsidiary of Wuerselen, Germany-based CemeCon AG, was founded in 1998 and the third increase in capacity for the CVD diamond process since 2014.
