The cast iron inspection square box is a precision tool widely used for checking the perpendicularity, parallelism, and flatness of workpieces in mechanical manufacturing, assembly, and measurement processes. It serves as a reliable reference surface and angle standard in machining and quality control.
Material & Manufacturing
The square box is made from high-grade cast iron, typically HT200-300, known for its excellent wear resistance, dimensional stability, and vibration damping properties. The casting is stress-relieved through natural aging or artificial annealing to ensure long-term accuracy and prevent deformation.
Features
High Precision: Machined to strict standards with surface roughness and flatness meeting inspection-grade tolerances.
Multi-surface Utility: Each of the six faces is precisely machined to serve as reference surfaces for different measurements and setups.
Reinforced Design: Ribs or hollow sections inside the box ensure structural strength while reducing weight for easier handling.
Corrosion Resistance: The working surfaces are protected by anti-rust treatment or finished with a precision scraping process.
Applications
Used for checking 90° angles between workpieces or between workpieces and machine tools.
Ideal for inspecting the flatness and straightness of components.
Serves as a fixture for assembling and aligning mechanical parts.
Commonly used in toolrooms, machine shops, laboratories, and metrology departments.
Available Sizes
Cast iron inspection square boxes are available in various standard sizes, ranging from 100×100mm to 1000×1000mm. Custom dimensions and inspection grades (e.g., Grade 0, Grade 1) can be provided according to customer requirements.
Advantages
Excellent rigidity and stability for long-term use.
High precision for quality inspection and calibration tasks.
Versatile use across different industries including automotive, aerospace, heavy machinery, and tooling.
This tool is essential for ensuring the accuracy and consistency of mechanical parts and assemblies, making it a valuable asset in any precision engineering or quality assurance environment.
