Shaft Testing in Forging Processes

Dimensional Accuracy Inspection
Use a coordinate measuring machine (CMM) or vernier caliper to inspect shaft diameter, roundness, and concentricity, ensuring geometric dimensions meet design tolerances. Evaluate form and position accuracy through multi-point measurement and statistical data analysis, providing a benchmark for subsequent processing.

Internal Defect Screening
Employ ultrasonic testing technology to focus on detecting internal defects such as shrinkage cavities and inclusions within the shaft body. The single straight-beam radial detection method efficiently identifies delamination cracks, ensuring material integrity.

Surface Quality Assessment
Detect surface cracks, folds, and other defects through magnetic particle or penetrant testing. Combine hardness testing with metallographic analysis to verify material structure uniformity and ensure shaft reliability.
