Sanxin designs and builds many machines for its own use and, within Mainland China, for use by its customers. The pictured machine, called the Sanxin 200US-1 is a wide range, frequency-variable ultrasonic grinding and polishing machine used extensively by Sanxin in its own factories. It is Sanxin's intention to supply this machine and other similar machines for use by customers outside Mainland China. Details will be reported on this website as they become available (see also LINE POLISHING M/C).
