This machine measures the Z-axis with extreme accuracy using laser beams. Non-contact image processing employing CCD cameras realize measurement accuracy of ±0.001 mm. A combination of CCD cameras and optical lasers provide enhanced measurement accuracy. Measurement accuracy is ±0.02 mm. This machine is used to measure the bond strength of adhesive tape and verify the peel-off balance of separators. The temperature and humidity are carefully controlled in this aging chamber, which enables us to test quickly how products change over time. It is used for quality assurance testing of products such as adhesive tape. This device enables three-dimensional processing by receiving image data from a camera. The camera zooms in on product cut faces and minute molded product surfaces at 50- to 5,000-times magnification, and the image data are three-dimensionally processed to confirm the conditions of these faces and surfaces.
