In industry, predictive maintenance is essential to guarantee the performance of machine tools. This equipment, often used in demanding sectors such as aerospace, automotive and nuclear power, represents a major investment, sometimes in excess of one million euros. To maximize their return on investment, efficient maintenance management is essential. This is where Lesly comes in, an innovative solution that uses predictive maintenance to anticipate failures and extend machine life.
What is Predictive Maintenance and why is it Crucial?
Predictive maintenance is based on real-time data analysis. Unlike preventive maintenance, which follows a schedule, it anticipates breakdowns before they occur. By monitoring critical machine tool components, such as spindles, axis motors and tools, predictive maintenance enables interventions to be planned optimally, thus reducing costs and downtime.
Lesly integrates this approach by analyzing CNC data and detecting early signs of failure. This technology prevents unplanned downtime and ensures uninterrupted production.
Lesly's Predictive Maintenance Solution
Lesly is an intelligent software that collects and analyzes data from machine tools to provide valuable information on their operating status. Using a machine learning system, Lesly can predict the wear of critical components. This system, based on the Km 0 concept, characterizes each machining program and monitors machine condition in real time.
Manufacturers can thus benefit from predictive maintenance, enabling them to plan repairs before problems arise. This avoids the costs associated with breakdowns and reduces the risk of production interruptions.
Maintenance frequency and types
Maintenance frequencies vary according to how intensively the machines are used. For intensive use, a check-up is required every 3 to 4 months, with preventive maintenance every 6 to 12 months. For moderate use, checks can be carried out every 6 to 9 months, with preventive maintenance every 12 to 18 months. Machines used occasionally can be checked annually, with maintenance every 18 to 24 months.
The different types of maintenance are :
- Preventive: Scheduled regularly to avoid breakdowns.
- Corrective: Intervenes after a breakdown, either to repair (palliative) or replace parts (curative).
- Predictive: Based on data analysis to anticipate failures.
Data Collection and Total Control with Lesly
Predictive maintenance is based on continuous data collection. With Lesly, machine tools are connected to the LeslyBox via an M2M (Machine-to-Machine) link. This enables intelligent, real-time data collection. Thanks to the Internet of Things (IoT), Lesly monitors parameters such as temperature, pressure and rotation speed.
Users can exploit this data via customizable dashboards, facilitating analysis of machine performance. What’s more, data can be exported to Excel for even more detailed monitoring. This gives manufacturers total control over the status of their equipment.
Cutting-edge technologies and data security
To guarantee data reliability and security, Lesly integrates intelligent sensors and advanced algorithms. These technologies enable precise, real-time analysis, facilitating decision-making. In addition, Lesly ensures secure data processing and protects against cyber threats. Sensitive information, such as machine data, is thus secured throughout the collection and analysis process.
The benefits of Predictive Maintenance with Lesly
- Cost reduction: Predictive maintenance helps to avoid unexpected breakdowns and minimize costly interventions.
- Extended machine life: By monitoring wear and tear on key components, Lesly helps prevent failures and extend equipment life.
- Saves time: Intelligent data collection enables fast, accurate analysis, facilitating proactive machine management.
