Swiss Precision

Swiss Precision

Swiss Precision manufactures precision dimensional measurement standards, with a focus on gage block sets used in metrology laboratories, quality control departments, and machine shops. Gage blocks — also known as gauge blocks or Johansson blocks — are hardened, precision-ground metal blocks that serve as reference standards for calibrating measuring instruments, setting comparators, and verifying dimensional tolerances in manufacturing environments.

Swiss Precision gage block sets are produced to meet international standards such as ASME B89.1.9 and DIN 861 and are available in various accuracy grades. They are used alongside micrometers, height gauges, and coordinate measuring machines (CMMs) to establish traceability to national and international measurement standards.

Key Product Lines

• Steel Gage Block Sets — precision-ground hardened steel blocks for general dimensional calibration and shop use
• Carbide Gage Block Sets — wear-resistant tungsten carbide blocks for high-frequency use and harsh environments
• Individual Gage Blocks — single blocks for custom dimensional reference and comparator setup applications

Industries Served

Swiss Precision gage blocks are used across precision manufacturing, aerospace, automotive, and metrology laboratories wherever dimensional accuracy and traceability to measurement standards are required for quality control, instrument calibration, and machining verification.
