[Case Study] No false detections even in harsh manufacturing environments! Unprocessed tap detector

Introducing a case study of the "Tap Unprocessed Detector NT-1," which is ideal for inline inspection and does not produce false detections even in harsh manufacturing environments resistant to water and oil!

【Customer's Challenge】 We want to eliminate false detections and prevent the outflow of unprocessed products! We inspect unprocessed products with a laser inspection device, and then inspectors conduct a visual inspection of all items in the subsequent process. However, false detections caused by the adhesion of cutting fluid frequently occur, leading inspectors to mistakenly believe that the inspection device has made a false detection even when a non-conforming judgment has been issued. As a result, defective products have been processed as good products, leading to the outflow of unprocessed products to customers. We have received a request to review the current inspection method. 【Proposal from Microfix】 The eddy current tap unprocessed detection device generates eddy currents in the inspected object through electromagnetic induction and makes judgments based on the differences in changes. Water and oil are insulators, so electricity does not flow, and even if they adhere to the tap holes, they do not affect the inspection results. Therefore, stable inspection accuracy can be maintained even in harsh on-site environments.
