Un site industriel détecte des dérives variateur et évite 8h de pertes grâce à Lesly PLC
Un acteur industriel majeur a déployé Lesly pour superviser en continu ses équipements critiques pilotés par variateurs. Dans un contexte de production continue à forte exigence de disponibilité, Lesly a permis de détecter des comportements anormaux sur plusieurs machines moteurs : passages non signalés en mode local, marches dégradées ou dérives mécaniques invisibles à l’œil nu.
Grâce à l’analyse continue de Lesly, plusieurs incidents ont pu être évités ou mieux documentés, conduisant à des ajustements de seuils et une meilleure maîtrise des risques opérationnels.
Naval Group sécurise l’usinage de pièces critiques grâce à Lesly CNC
La collaboration entre Naval Group et DIANALYSE s’est construite autour d’un objectif commun : garantir la performance et la sécurité des équipements de production critiques.
Grâce à Lesly CNC, la machine AM75 bénéficie d’un suivi temps réel de ses signaux internes, notamment les signaux TUPC, permettant de détecter proactivement des dérives invisibles aux systèmes classiques.
For our clients, Lesly guarantees high-performing machines.
We implemented Lesly at Lactalis on the Shaka equipment to maximize its availability and reduce costs. Thanks to Lesly, we intervene in less than 2 hours where heavy maintenance was previously required. This allows us to avoid unplanned shutdowns that could cost up to €5,000 per batch. With an investment of €25,000 and €5,000 per year, the return on investment is immediate.
We deployed the Lesly solution on our machining tools to better anticipate tool wear and reduce our production costs. Thanks to Lesly, the lifespan of our tools has increased by over 30%, and we now detect anomalies one week before sensor alerts.
This allows us to avoid costly interruptions, improve the quality of our parts, and optimize the maintenance of our equipment. The impact on our performance and production reliability has been immediate.
Thanks to the Lesly solution, we have achieved a major milestone in monitoring our critical machines. On one of the machining machines with a long production cycle, continuous analysis of spindle head drifts allowed us to anticipate failures before they impacted production. The indicators and alerts generated by LeslyAI proved remarkably reliable, validated by our internal control methods. As a result, we have improved machining quality, reduced rework costs, and optimized our preventive maintenance cycles. This collaboration has brought us real peace of mind in monitoring our equipment.
