Non-Contact Roundness / Cylindricity Measuring Instruments

Non-contact cylindricity measuring instruments

  

This is the result of cylindricity analysis of φ1.27mm pin gauge.
Because it is non-contact, the work can be measured without bending due to tactile pressure.
In addition, the stamp of "1.27" can be measured.

Comparison of contact and non-contact

      
       Tip radius φ0.8mm       Tip radius φ0.025mm Trispy(Spot diameter0.001mm)

This is the result of roundness shape analysis of the inner diameter of the engine bore.
It is a comparison of the results of the two types of stylus tip radii and the non-contact detector Trispy.
At φ0.8 mm, a convex shape can be seen due to the influence of dust, etc., but at φ0.025 mm, there is no influence of dust, etc., and a concave shape that penetrates into a fine groove can be seen.
Since the spot diameter of the non-contact detector is 0.001 mm, many concave shapes that go into finer grooves can be seen.
