Due to their high hardness, excellent wear resistance, and excellent dimensional stability, cemented carbide calibration balls are widely used as calibration tools in many fields with stringent precision requirements.
Main application scenarios of cemented carbide calibration balls:
1. Calibrating Precision Measuring Equipment
Calibrating Coordinate Measuring Machines: A cemented carbide standard ball with known precise dimensions and roundness is fixed on the worktable. By measuring the spatial position of its center, the coordinate accuracy of the measuring machine is calibrated and verified.
Calibrating Roundness Testers and Profilometers: Using the near-perfect sphericity of the cemented carbide calibration ball as a benchmark, the accuracy of the instrument in measuring the roundness and profile of workpieces is evaluated.
Calibrating Surface Roughness Testers: The extremely high surface finish of the cemented carbide calibration ball is used as a reference standard to calibrate the measurement parameters of the surface roughness tester.
Calibration of Optical Instruments: Cemented carbide calibration balls are frequently used as calibration targets in equipment such as laser interferometers due to their stable geometry and high reflectivity.
2. As the core component of the measurement probe
The tip of the measuring head used for coordinate measuring machines and roundness meters. A replaceable measuring head used for measuring tools such as inner diameter gauges, and cemented carbide calibration ball with high hardness can significantly reduce wear and tear, with a lifespan ten of times longer than traditional steel balls, and avoid scratching precision workpieces.
3. Supporting High-End Manufacturing and Scientific Research:
Aerospace: Used to calibrate machining centers and testing equipment, ensuring that the manufacturing of critical components such as engine turbine blades meets extremely stringent tolerance requirements.
Automotive Industry: Plays a crucial role in calibrating bore diameter and roundness measurement instruments for components such as engine cylinder bores.
Petroleum and Aerospace Sealing Inspection: Dedicated gasket groove ball gauges use cemented carbide calibration balls as probes to accurately measure the dimensions of pipe valves and aero-engine sealing grooves, achieving micron-level accuracy.
Oil and Aerospace Sealing Inspection: Cemented carbide calibration balls are used as probes in specialized gasket groove ball gauges to precisely measure the dimensions of pipe valves and aero-engine sealing grooves. Scientific research: At the nanoscale, cemented carbide calibration spheres can serve as standard samples for calibrating cutting-edge scientific research equipment such as scanning probe microscopes or atomic force microscopes.
