Rebar Machine Maintenance: How to Make Your Machine Last 20 Years

The difference between a machine that gets replaced after eight years and one that still bends precisely after twenty rarely lies in the machine itself. It lies in the maintenance. GMS machines from the 1990s are still working around the world today. That is not luck, it is the result of a simple maintenance routine.

Daily: 5 minutes that pay off

Before the shift: visual check for loose parts, damage to cables and controls, function test of the emergency stop. After the shift: clean the machine of steel dust, scale and debris. Metal dust is the silent enemy of every mechanism, because combined with grease it acts like grinding paste.

Weekly: lubrication by schedule

Grease all lubrication points according to the manufacturer’s plan, especially the bending disc, bearings and guides. Use only approved grease types. Also inspect bending mandrels and blades: worn tooling produces poor results and strains the drive.

Monthly: electrics and wear parts

Check electrical connections, inspect the control cabinet for dust and moisture, examine belts and drive elements for tension and cracks. Keep a simple maintenance log: date, task, observations. When you sell the machine later, a complete log is worth real money.

Yearly: the full inspection

Once a year the machine deserves expert hands: check or change gearbox oil, measure bearing play, calibrate angle accuracy, test all safety devices. GMS Germany supports you with original spare parts and technical service.

Take the warning signs seriously

Unusual noises, growing angle deviations or longer cycle times are early warnings. Ignore them and a 50 euro repair becomes a 5,000 euro failure.

Conclusion

Five minutes daily, a fixed weekly routine, one annual inspection. That is all it takes for a GMS machine to earn its keep for decades. For spare parts and service questions: contact us.

FAQ

How often do bending mandrels need replacing? It depends on workload and steel grade. Check weekly for grooves and flat spots. A worn mandrel damages the ribs of the rebar and distorts the bending radius.

Which grease is suitable for bending machines? The multi purpose greases for heavily loaded bearings approved by the manufacturer. The exact specification is in your machine’s manual.

Are spare parts still available for older GMS machines? Yes. Long term spare part availability is part of the GMS Germany philosophy, including for machines that have been in service for decades.
