HOMMEL-Etamic has developed an optical inspection system which automatically detects bore flaws such as cavities, valleys, scratches, porosity and unmachined surfaces.
Often, the effective performance of parts and components is dependent on the quality of the surface finish. Brake master cylinders, connecting rods, injection systems and valves are some components especially sensitive to finish quality.
Previous methods involved operators using a bore scope to look for imperfections, creating a bottleneck in high-volume production environments.
The IPS-10 system can automatically inspect the finish of bores as deep as 450mm with diameters from 14 to 50mm. It is said to have a rapid scan rate, allowing seconds-long inspections.
The system consists of a computer, an optical sensor and a slide which positions the sensor inside the bore. During operation, the sensor creates a panoramic view of the bore’s surface finish. The solution can be configured to define various inspection and flaw-detection parameters.
The automatic optical inspector is set up by scanning and capturing the image of a flawless bore surface. The users then define inspection areas as well as key features once, and then the system is ready for automatic operation.
