What Is a Calibration Block?
A calibration block is a precision-engineered metal block used to check the accuracy of coordinate measuring machines (CMMs). Its dimensions are precisely defined and traceably calibrated to national standards, making it an essential tool in various industries including manufacturing, automotive, aerospace, and medical devices.
This block contains multiple reference surfaces for the CMM’s probe to measure. By comparing these measurements with the block’s known dimensions, the accuracy of the measuring machine is verified. Characteristics of calibration blocks include high precision, repeatability, and durability. They are valued for their ease of use and reliability, underpinned by traceable calibration.
Effective utilization requires careful handling to prevent damage and regular calibration to ensure continued accuracy.
