Automatic detection of scratches and dents on the shaft surface. Digitizing inspection results to streamline quality control.
Shaft products used in machine tools require stable surface quality to maintain processing accuracy. In particular, minor scratches, dents, and dirt on the shaft surface due to prolonged operation can potentially affect the accuracy of the final product. Traditional visual inspections have faced challenges, as it is difficult to retain records of inspection results, making it hard to utilize them for quality improvement and cause analysis. Our shaft appearance inspection device detects scratches, dents, and dirt on the shaft surface using image processing technology and optimal lighting conditions. Since inspection results can be stored as image data, they can be used to understand quality trends and analyze defect factors. [Usage Scenarios] - Quality control of shaft products at machine tool manufacturers - Detection of scratches, dents, and dirt on shaft surfaces - Quality improvement through recording and analyzing inspection data - Reduction of variability in visual inspections and promotion of labor-saving measures [Implementation Effects] - Recording inspection history to understand quality trends - Supporting quality improvement activities through the utilization of inspection result data - Reducing variability in visual inspections - Lowering the risk of defective products being released - Streamlining and increasing the efficiency of the inspection process

Company information
Founded in December 1937 in Handa City, Aichi Prefecture, we began manufacturing hydraulic cylinders for industrial vehicles in 1956 and have continued to be loved by major industrial vehicle manufacturers. In January 2019, we announced an inspection device that made it possible to inspect scratches on glossy surfaces, which was previously considered impossible. Since then, we have received numerous inquiries from finished product manufacturers.
