Since established in 1989, we have been co-operating with GE USA in researching and manufacturing a wide range of stone and concrete cutting tools.
Over the years, after acquiring knowledge and experience, we have invented and patented Diamond Arrangement Technology in 2008, which is the most advance diamond tools production technic in the industry. Now Kaiyuan has earned itself a distinction of providing "the lowest cost of cutting" without compromising on any aspect of quality.
