Almost all YAG laser cutting machine manufacturers like DNE laser, HSG laser...Used our CHC-300 cap sensors for laser cutting height control. Just because of that, Our cap height sensor CHC-1000 series for fiber laser cutting got delayed. When our CHC-1000 came to market in 2015, Cypcut system has taken all fiber laser cutting market in China. Simultaneous YAG laser cutting was being replaced by fiber laser cutting fastly. We had to work with PA8000, Beckhoff such foreign controllers for pipe cutting, laser welding and Robotic cutting...etc. Meanwhile, we started to offer complete fiber laser cutting machine, and machine integration service like robotic laser cutting, customized laser welding...Which opened a new world for us! More and more professional engineers joined our team in recent years, which enable us to make more and more automation solutions to clients around the world.
