The challenge for every manufacturing responsible person is called “Performance”. Independent of the industry or the location of the facility, a top performance must be achieved. However, the definition of performance varies depending on the economic situation. For the ones who operate under high market demand, output is key and consequently, availability and production rate are the key indicators. If environmental footprint is your company´s focus, electrical and thermal energy consumption will be a driving force. And if your margin is under pressure, you will be asked to get your operational and maintenance costs down.
The dilemma between operation and maintenance
Whatever your performance target is, the wellbeing of your machines plays a key role for goal achievement. Because of this well-known context, maintenance processes, maintenance education, and maintenance systems are applied to keep the machinery in good condition. Now, you could do as much as possible or as less as necessary to keep the operation running. The “effort versus result” dilemma plays an essential role in the definition of your maintenance strategy. This dilemma gets even more emphasized with the shortage of qualified technicians, which is a reality in nearly every manufacturing site.
When Predictive Maintenance can support you
If the following statements are true for your maintenance, predictive maintenance can create real value for you.
In a perfect maintenance world, you would have enough qualified technicians to maintain the equipment according to OEM´s instructions and routines. Machines would be available for maintenance, even for detailed investigations and replacement of weak components. As you are not acting in wonderland, your CEO will do his job asking for optimization.
Now, reality kicks in and you are cutting down resources, evaluating and taking risks related to the reliability of your machines. Often, this results in a focus to the main equipment or the large and expensive machines, leaving the auxiliary equipment behind, getting maintained if time permits.
With this, you will achieve the goals of decreasing costs, and low staffing. In the long term, however, this strategy is highly likely to fail due to high risks for unforeseen downtimes, high failure costs and therefore, decreasing productivity and performance!
So, how to solve this Gordian knot between operation and maintenance? With smart machines based on Predictive Maintenance!
Win-win for machine manufacturers and maintenance managers – how Predictive Maintenance breaks the Gordian knot between operation and maintenance
Many machine manufacturers have been successful in the market for decades based on robust machines, stable markets, and loyal customers. With the growing globalization and transparency, market rules constantly change. Plants expect high machine reliability, state-of-the-art products and services, and cost-efficiency.
With the latest developments of IIoT technology and algorithms, Predictive Maintenance can change how business can be done and create a win-win-situation for both: machine manufacturers and machine owners. Smart machines with its insights enable us to learn from the past, predict the future and thus, proactively act instead of reacting.
- Based on Predictive Maintenance, the machine operator will know ahead of time when a failure develops and can initiate the related maintenance work. At the same time, the OEM gets notified too. He prepares the required parts and plans the service staff. This does not only reduce the unplanned downtime but also reduce the maintenance and warehousing costs due to optimized planning and less emergency cases.
- If the machine is still maintained in a reactive way, Predictive Maintenance opens the door to offer new proactive service models aiming for maximum production and supporting the maintenance team best possible. The OEM might even offer a full service, backed up by the online machine information or 24/7 support. This helps to reach maximum production by optimized maintenance without taking unnecessary risks.
- Another starting point can be new operation models like “pay per use” or “pay per outcome”. Specifically, if CAPEX funding is a topic, these models can be the OEM’s answer to support Maintenance Managers keeping their budgets.
- Thanks to the well-known machine performance and condition, the OEM can detect machine weaknesses and improve the quality and reliability of his machines and spare parts, which is key for the maintenance manager. Furthermore, he can offer new products and services like machine optimization, refurbishments, or apply the observations for new developments. This helps maintenance managers to keep machine reliability high and optimize costs by upgrading existing machines.
So, how can this look like as a real case? An example:
A ball mill for cement grinding is running 24/7. A failure of the discharge elevator will result in a production stop and is therefore categorized “process critical”. So, how to detect anomalies on time to prevent a possible breakdown without doing regular maintenance? This is a typical case for a Predictive Maintenance Solution monitoring the condition of the elevator. It informs about the condition of the machine in real-time, sends push notifications in case of anomaly detection, and provides a prediction of the estimated service life of critical machine components (e.g. it predicts the point in time for a chain shortening or chain replacement). Of course, it does not eliminate all of the maintenance routines nor replaces the maintenance team. However, it is the best buddy enabling to set priorities in maintenance, decide what to do next, and act!
Preparation is key to create value from Predictive Maintenance
For a successful implementation, there are several requirements to be fulfilled or established. Choosing the right maintenance strategy and a careful preparation of its implementation is key. Carefully think about your challenges and select the machines you want to upgrade accordingly.
Fit for the future with Predictive Maintenance
Predictive Maintenance can be a good solution to plan and do regular maintenance activities, detect, and optimize machine weaknesses at an early stage and proactively ensure maximum production without taking risky compromises in maintenance. With a closer collaboration between machine manufacturers / OEMs and customers, the combination of optimal maintenance and maximum production is achievable.
The integration of digital technologies, such as Predictive Maintenance, enable new forms of data collection and analysis, which can be used to gain insights and make more informed decisions. A win-win-situation for both: machine manufacturers and customers.
