Ultrasonic horn wear assessed through amplitude visualization! Laser Doppler vibrometer
LV-1800
Escape from uncertain lifespan management where you don't know when to replace! Quantify the amplitude of the horn tip non-contactly to achieve the prevention of welding defects.
■ Breaking away from "intuition and experience" in horn management Are you facing the following issues with ultrasonic processing machines and welding machines? - Variability in welding strength and processing accuracy despite unchanged conditions - Inability to visually assess the wear condition of the horn, making it difficult to determine the timing for replacement These troubles arise from the gap between the device's output settings and the "actual tip amplitude." Invisible amplitude reduction due to wear can trigger sudden losses of defective products. ■ Accurately visualizing "horn amplitude" with non-contact measurement The Laser Doppler Vibrometer 'LV-1800' provides completely non-contact measurement that does not affect the weight of the target object, accurately quantifying the amplitude of ultrasonic tools. By incorporating a positioning camera, it enables reliable and easy laser irradiation even in narrow devices or at the tips of small horns. The LV-1800 helps establish a clear quantitative maintenance rule of "replace when amplitude falls below the specified value" by measuring the actual amplitude. ★ Free materials available You can download a flyer with specific case studies and a product catalog from this page. *For detailed specifications, please download the PDF materials or feel free to contact us.*
