Qingdao Qianshao Precision Instrument Co., Ltd. is a national second-level enterprise affiliated to the Aviation Industry Corporation of China and a national first-level measurement unit. In 1993, it was the first company in the aviation industry to obtain ISO9001 quality system certification. The company's main products include: grating length measuring machines, high-precision vertical detectors, high-precision straightness detectors, large-size baseline devices over 50 meters, digital electronic levels, granite air bearings, granite precision measuring tools, granite precision measuring tools, etc. Products such as granite precision components, product quality and processing and testing technology are in a leading position in the country.
Granite precision measuring tools and precision component products were developed by the company for the first time in China in 1979. There are currently 8 series and more than 40 varieties. We can also process measuring instruments, machine tool bases, lathes, beams, guide rails, columns and other granite accessories according to the different requirements of users.
Relying on granite precision processing technology and the company's patented air suction and flotation technology, we develop grating length measuring machines, high-precision verticality detectors, high-precision straightness detectors, and large-size baseline devices of more than 50 meters. Such new products can meet the different needs of users with high precision and high reliability.
The digital display electronic level was developed by the company in the early 1980s. It has high measurement accuracy, fast speed and intuitive reading, and is suitable for the measurement of straightness, flatness and parallelism. This product uses the software and interface we developed to form an automatic detection system with a computer, which can improve detection speed and accuracy. It is listed as a substitute for imported products by the country. In the past two years, the company has developed a fully digital level meter and a fully digital electronic inclinometer, which have added many convenient and practical functions, enabling precise measurement of small and large angles, and can better serve customers.
The company has more than 260 employees, including more than 30 intermediate professional technicians and 6 senior engineers. The machine shop covers an area of ??more than 5,000 square meters, has 7 central air conditioners, and a constant temperature processing area of ??more than 4,500 square meters. There are 5 large and small laboratories, more than 60 sets of various processing and lifting equipment, and a 4×2 meter CNC drilling and milling machine, a 5×3 meter drilling and grinding machine, the company’s own fully digital electronic level, and the British Renishaw* latest double Frequency laser interferometer, Swiss TETA's inductive micrometer and other advanced processing and testing equipment, all detection data are processed by computers.
The company has established a subsidiary "Yinan Qianshao Precision Granite Manufacturing Company" covering an area of ??100,000 square meters in Yinan, Shandong Province, which provides a favorable guarantee for the company's sustainable development.
The company has self-operated import and export rights, and 60% of its products are exported to the United States, the European Union, Japan, Taiwan, Singapore and other countries and regions. "Integrity-based, quality first" is our constant pursuit, and providing customers with satisfactory products and services is our solemn commitment. The company's chairman Jiang Zhide and general manager Mr. Li Zhenhe warmly welcome people from all walks of life at home and abroad to come to the company to negotiate and discuss development plans!
