Slip gauges, also known as gauge blocks, are precision tools used in dimensional measurement. Their standard
cross-sectional size is 32 mm × 9 mm, ensuring uniformity and ease of stacking during calibration or inspection processes.
Purpose of Slip Gauges:
It provide accurate dimensional references for setting tools and measuring instruments.
It is used in metrology for calibration and inspection tasks.
Materials:
Commonly made of hardened steel, ceramic, or tungsten carbide for durability and resistance to wear.
Types of Slip Gauges:
1. Metric and imperial.
2. Standard grades: Workshop (grade 2), inspection (grade 1), and calibration (grade 0 or higher).
