Introduction to Step Blocks

Step blocks are essential calibration tools used in various industries, especially in the field of metrology and quality control. They are typically made of high - precision materials such as granite or steel and have a series of steps with precisely defined heights. These steps are used to calibrate measuring instruments like calipers, micrometers, and coordinate measuring machines (CMMs). By comparing the measurements of the instrument under test with the known step heights of the step block, the accuracy and precision of the measuring device can be verified and adjusted if necessary.
