1. 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. 2.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. 3.ANYI-Step is not only an ideal mechanical reference artifact for calibration, monitoring and traceability of CMMs, but also for machine tools, maching centers and height gauges. 4.Nominal lenght from300 mmup tomaximal 1500 mm. Special lengths upon enquiry. 5. The standard block pitch (increments, the distance betweenevery two close workingblocks)is 20 mm. We accept customizedgauge blocks arrangement. 6.Steel gauge blocks, carbide gauge blocks and ceramic gauge blocks are optional.
