The hydraulic press is the beating heart of many workshops and industriesTo avoid costly downtime and ensure a long operating life, it's essential to implement a rigorous maintenance plan. Well-maintained machinery not only performs better, but also dramatically reduces the risk of injury.

1. Fluid Control and Filtration

The hydraulic system is entirely dependent on the quality of the oil. The presence of debris, air, or water in the circuit is the main cause of valve and seal deterioration.

  • Oil level: Check daily that the level is optimal.

  • Oil Analysis: Once a year (or depending on working hours), it is advisable to carry out a chemical analysis to detect metal particles or oxidation.

  • Filter replacement: Oil filters should be replaced regularly to prevent pump cavitation.

2. Inspection of Seals and Cylinders

Fluid leaks are the most common warning sign. A small leak can quickly turn into a critical pressure drop.

  • Check gaskets: Inspect the pistons for scratches or excessive oil on the cylinder liner.

  • Tightening fittings: Constant vibrations can cause fittings to loosen. A visual and manual check prevents sudden leaks.

3. Lubrication and Mechanical Structure

Not everything is hydraulic; the mechanical part requires just as much attention.

  • Greasing: Many presses have self-lubricating slideways, such as those produced by SICMI. If your press doesn't have this system for the sliding platen slideways, it's necessary to lubricate them regularly to avoid asymmetrical friction that could compromise the press's precision.

  • Alignment: An out-of-alignment press performs poorly and wears components unevenly. Periodically check the parallelism of the plates.

4. Electrical and Safety Maintenance

Sensors and arrest systems are vital.

  • Photocells and barriers: Test the correct functioning of optoelectronic safety systems daily.

  • Wiring: Check that the cables are not worn or exposed to excessive heat sources.

Conclusion: Prevention as Savings

Following a preventative maintenance checklist allows you to identify small problems before they become catastrophic failures. Remember that an efficient hydraulic press consumes less energy, produces higher-quality parts, and protects the physical integrity of operators.
