In 2009, approved by the Ministry of Science and Technology (MOST), the Partner State Key Laboratory of Ultraprecision Machining Technology (PSKLUMT) was established by PolyU. It was the partner of State Key Laboratory of Precision Measurement Technology and Instruments in Tianjin University and Tsinghua University. In September of 2018, it was approved by MOST to rename as the State Key Laboratory of Ultra-precision Machining Technology (SKL-UPMT). The laboratory, formerly the Ultraprecision Machining Centre (UMC), was established in 1996. The objective of the laboratory is to undertake research on ultraprecision machining technologies and precision surface metrology so as to enhance the capability of Hong Kong and Mainland China in the design, fabrication and measurement of advanced optics and critical precision components.
