The Small Bore Surface Replicator was developed to examine the surface finish in difficult-to-measure small bores.  Small diameter parts with critical surface finish features can prove very difficult to measure with standard equipment.  By leveraging technology used to create precise surface finishes on small bores, C-K Engineering has created a surface measurement system that can reach where no profilometer can!  A two-part silicon rubber compound is used to make a 3-dimensional negative copy of the bore surface, which then can be analyzed with a non-contact surface analyzer to provide all the vital surface finish data you need.  The Small Bore Surface Replicator will allow you to accept or reject parts on the basis of surface finish from anywhere along the bore, not just on the ends, or from estimates made with visual equipment.
