Calibrate and check (110)

Reference bodies and holders

Reference bodies ensure the measuring accuracy in everyday life, and this with reference to each new measurement. They can be optical templates, calibration spheres, ring gauges or triplets, all of which have a zero point in their center to guide the coordinate measuring machine. Depending on the measuring environment, thermally stable or standard holders are available for positioning the measuring body. All services and products related to the coordinate measuring machine are available from ZEISS from a single source. This applies to calibration on behalf of customers as well as to the tools for independent alignment of the device.

ZEISS calibration artifacts - conforming to standards

Coordinate measuring machines shall be inspected regularly according to ISO quality standards 9000-9004. The procedure for acceptance and confirmation testing is described in detail in ISO 10360. The test specimens with their high-precision calibrated values, corresponding to the standard-compliant procedures for coordinate measuring machines according to VDI/VDE 2617 Sheet 5 and DIN EN ISO 10360, serve as a reference. In addition, VDA 5 and VDI/VDE 2617 Sheet 8 are decisive for determining the suitability of the test process. The test specimens are also suitable for testing contour measuring machines according to VDI/VDE Guideline 2629; for certain geometric elements the measurement uncertainty can be determined according to ISO 15530. Such a basic adjustment of the measuring instrument according to the standard is scheduled once a year. In addition, it is advisable if there are doubts about the accuracy, for example after temperature fluctuations or mechanical damage.
