Product Overview
Metal precision gauge blocks (also known as "gauge blocks") are rectangular standard measuring tools made of high-hardness alloy steel, tungsten carbide and other high-quality materials. They are widely used for calibrating measuring instruments (such as micrometers and calipers), or directly for precise measurement of work piece dimensions. Common precision grades include 00 grade and 0 grade, with dimensional tolerances controlled within ±0.1 microns, ensuring the accuracy and reliability of each measurement.
Core Features
1. Ultra-high Precision: The surface is finely ground to achieve a mirror-like finish with minimal flatness error, providing reliable support for your measurements.
2. Stable Material: Made from high-quality materials with low thermal expansion coefficients, effectively reducing the impact of temperature changes on measurement results and ensuring long-term stability.
3. Flexible Combination: Advanced lapping technology allows for the stacking of multiple gauge blocks to easily expand the measurement range and meet diverse measurement requirements.
Typical applications:
- Instrument calibration in laboratory and factory metrology rooms
- Precision dimension verification in mechanical processing fields
- Key tools in quality control and inspection processes
Key Points for Selection
1. Precision Selection: Choose the appropriate precision grade (00 grade or 0 grade) based on actual needs. Among them, the 00 grade is suitable for scenarios with higher precision requirements.
2. Material Consideration: Tungsten carbide has excellent wear resistance but is relatively expensive; alloy steel offers a good balance of performance and cost-effectiveness, making it the ideal choice for most users.
3. Certification Assurance: Prioritize products with authoritative certification such as ISO 9001, CE, SGS, TUV, or AAA grade to ensure reliable quality.
Advantages in the Foreign Trade Market
Metal gauge blocks produced in China have gained a significant position in the global market due to their outstanding precision and highly competitive cost advantages.
