Challenge the unknown. Leave it to us for ultra-precision special mirror polishing services and the design and production of automatic assembly machines.

Common to semiconductor manufacturing equipment, medical and analytical instruments, aerospace-related fields, and nuclear-related applications is the extensive use of clean pipes in fluid-carrying piping systems. Our polishing technology is original, utilizing methods that address shapes deemed "difficult or impossible" in electrolytic polishing, chemical polishing, buffing, lapping, and grinding to meet our customers' needs. We specialize in the internal polishing of thin tubes, bent pipes, tapered pipes, and irregularly shaped pipes. Our techniques are applicable to materials such as stainless steel, titanium, ceramics, Inconel, and quartz. This is a specialized polishing technology that continues to challenge ultra-clean technologies.
