Gauge Blocks

Gauge blocks, also known as slip gauges, are high-precision measuring standards used to set, check, or calibrate other measurement tools. They are finely finished blocks of fixed lengths that can be wrung together to create a desired measurement.

Key Features

• High Precision: Manufactured to strict tolerances, often within sub-micrometer accuracy.
• Wringability: Can be stacked tightly together via wringing for accurate length combinations.
• Dimensional Stability: Designed to maintain accuracy over time with minimal dimensional drift.
• Laser-Etched Markings: Clear, permanent labels for easy identification.
• Available in Multiple Grades: Workshop (Grade 2), inspection (Grade 1), and calibration (Grade 0 or 00).

Common Materials

• Steel: Durable and widely used; susceptible to corrosion.
• Ceramic (Zirconia): Rust-proof, wear-resistant, non-magnetic, and ideal for harsh environments.
• Carbide: Extremely hard and wear-resistant; suitable for frequent use.

Applications

• Calibrating measuring instruments such as calipers, micrometers, and indicators.
• Setting machine tools and checking fixtures or gauges.
• Length measurement in metrology labs or quality control departments.
• Reference standards in manufacturing and inspection processes.

Benefits

• Ensures measurement traceability to national or international standards.
• Improves measurement consistency and repeatability.
• Reduces error in high-precision machining and inspection.
• Saves time by enabling fast, accurate tool setup and verification.
