Detection Objects: Surface cracks and sand holes on the inner and outer walls of piston bushings, including straight-face bushings, arc-face bushings, and bevel-face bushings.
Bushing Dimensions:
Outer diameter: 17–95 mm
Inner diameter: 15–70 mm
Height: 18–55 mm
Detection Host: DSSEN FET-99S Multi-Channel Intelligent Digital Eddy Current Flaw Detector
System Detection Process
Two detection stations for inner and outer walls, with each station calibrated and detected in three zones: bevel face, straight face, and notch face.
Angle masking can be applied to notches as needed, masking only the notch itself rather than the entire circumference where the notch is located.
Semi-automatic feeding, automatic detection, and automatic sorting.
Detection Speed: 8–13 seconds per piece (varying by whether notch masking is applied)
