Features :

    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.
     (Link: How To Use Step Gauge ?)


       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 .

      Nominal lenght from 300 mm up to maximal 1500 mm.
      Special lengths upon enquiry
      20 mm increments (customized increments upon enquiry)
      Steel gauge blocks, carbide gauge blocks and ceramic gauge blocks are optional.
