Cylinder inner wall inspection

The CylinderInspector is an optical, non-destructive inspection and measurement tool for cylinder bore surfaces.

It is designed to inspect honed surfaces of cast iron and aluminum. Furthermore, the composition and distribution of silicon crystals in aluminum can be analyzed.

The CylinderInspector is the first choice in inspection equipment by many automotive and engine manufacturers, worldwide.


  • non-destructive image analysis using high-end optics for perfect images of the cylinder inner wall
  • optical zoom to realize different magnification & detail views
  • full 360° all-round view as well as variable immersion depth
  • illumination variants for the best possible image quality of differently treated surfaces
  • extensive selection of accessories (interchangeable adapters, calibration targets, etc.)

Added value

  • precise and repeatable measurement of cylinder bore surfaces
  • Standardization of inspection processes at supplier and customer for improved quality assurance in production
  • Modular, high-performance software for parameter determination of various parameters such as honing angle, pore size and distribution
  • Definition of sample and type-related limit values
  • Customizable program interface and measurement data reports

CylinderInspector V4

The CylinderInspector 2D is ideal for quality control in measurement laboratories and development environments with medium sample numbers. It enables precise and repeatable measurement of predefined parameters. Fast inspection processes significantly increase control over cylinder crankcase production, ensure a consistent production flow as well as improved product quality.
