Quality assurance systems introduce:

Zhejiang Rifa holding group carried out TQM at the beginning of her foundation. In 1999, according to ISO9000 requirement, she established quality assurance systems and gain ISO9001 Certification; more so, she updated the certification 94 version to 2000 version in Dec.2002 (Certification No. 15/02Q5180R11)

On the basic of ISO9001 systems, our group pursuit of “precision, smart and international” as the whole stratagem. Pursuit the target of keeping in providing high satisfactory products and good service for solving problems. Benchmarking from the famous company in the world and taking the TCS (total customer satisfaction) as our improving power, we established the quality system throughout the products whole lifecycle, providing entire products and services quality assurance from design quality, manufacture quality and maintenance quality.

Inspection measurement and test assurance system

Our group established inspection measure and test center at present, there are 2 members for fulltime inspection measurement management and 15 members for part time management. There are three measure standards, these help us to do geometry inspection measurement and test facility's' calibrations and test items. In Aug.2003 we gained the Certification for the system of inspection measurement and test. (No.: (2003) 量企浙绍字 (009) 号 )

Our group possesses HP laser interferometer, Omnipotence microscope, roundness tester, optic collimator, digital spinning twist tester, filoplume tester, electron scale etc. it meets all kinds of products' completely testing requirements; our group adopt ISO10012 international standard, we established a comparative complete measurement management system through keeping in improving and adaptation. It provides the whole group products quality management reliable measurement guarantee.

CX-1 Roughness and contour measurement

CX-1 Roughness and contour measurement especially use in bearing industries' raceway contour test, this set adopt diamond pin, inductance tap and encoders, at the same time it adopt PC automatic control, it is very convenient and can finish task within seconds. This ensures the high precision in measurement and good in repeatability.

HP5529A laser interferometer
Usage: HP laser interferometer is a high precision measure instrument; it is used widely in high precision mechanical industry, such as air industry and manufacture industry. It is mainly used in measuring flatness, straightness, parallelism and angle error etc; It is also used in measuring CNC axis orientation precision, repeat orientation precision and reverse deviation.

Digital spinning twist tester
Usage: It is used in measuring deferent spinning related technical index, and can meet National standard GB2543.1.2-89 and national industry standard fz/t10001-92, PC control, automatic dealing with data, display and print data directly.

Roundness tester
Usage: Round test users were also pleasantly surprised with the system's ease-of-use. The operator places the core on the turntable, which is suspended by a high-precision air-bearing to prevent fatigue wear. A digital adjustment table (DAT) mechanism assists in centering and leveling the work piece in minutes. The turntable digitally displays the centering and leveling adjustments on the LCD. Simply pressing the auto-set key automatically brings the detector into contact with the work piece and stops it at the zero point. The operator punches in the part identification number in a computer program and walks away. It can used convenient in measuring roundness, thickness deviation, parallelism, co-axiality, spiral cylindricity, flatness, concentricity, squareness, cylindricity, straightness etc.
