Precision Step Gauge  may also be known as master gauge block set, standard reference bars, check  master ,or as calibration master. They are named so because it has the ultimate  accuracy and is used as the standardised artifact. To calibrate a Co-ordinate  Measuring Machine with a laser interferometer is time consuming and costly.  Precision Step Gauge provides a cheap and effective way of assessing the  performance of a Co-ordinate Measuring Machine (CMM) for a length measuring  task. It has been proved highly informative for calibrating the length  measurement uncertainty of CMM. Precision Step Gauge ANYI-Step requires short time  for preparation and measurement. 
     ANYI-Step is not only an ideal  mechanical reference artifact for calibration, monitoring and traceability of  CMMs, but also for machine tools, machining centers and height gauges.

    ANYI-Step has standard gauge blocks aligned and mounted in the  groove of body. The combination of the working surfaces of its gauge blocks can provide standard lengths of uni-direction and bi-direction. 
    10mm is the smallest increment which can verify the positioning error of  the guide rail and provide precision correction. Customized increments are  available upon enquiry 
    Anyi-Step can be used  horizontally or vertically. With its swival support, it can be used in  different angles. It can be customized for special purpose.

         Every Anyi-Step is with its manufacturer’s calibration certificate. Calibration certificate issued by National Institute of Metrology can be provided if customers pay for the calibration .
