Gauge Block: Precision Dimensional Measuring Standards

This page provides an overview of gauge blocks (also known as slip gauges), which are precision measuring instruments used for dimensional calibration and verification. Made from high-quality steel or ceramic, they feature extremely flat and parallel surfaces, offering accuracy within microns. Topics include their design, grading, applications in metrology, and usage in workshops and laboratories.

High-precision gauge blocks and slip gauges are required for accuracy. The parts that make up these devices are manufactured from steel and ceramic and superfine flat surfaces (flatness ≤0.0002mm). These measuring tools undergo calibrations that guarantee traceability, offered through the calibration gauge blocks. Slip gauges preset powers IT0 with preset slip gauges for the range of 0.5mm to 1000mm. These tools are used with CMMs and optical comparators in the automotive and aerospace industries using international standards ISO 10360 and ASME B89.1.9.

Frequently Asked Questions

What size ranges do gauge blocks cover?

They range from 0.5mm to 1000mm in metric/inch systems, with incremental sets for custom lengths via wringing, achieving sub-micron accuracy.
