Frequently Asked Questions
What sheet metal thickness can it bend?
See "Max thickness" in the technical table: typically 1-3 mm on mild steel.
Capacity refers to S235JR steel. For stainless steel or high-strength materials, the actual capacity may decrease to 60-70%.
What is the minimum bendable diameter?
See "Minimum bendable diameter" in the technical table.
The minimum diameter depends on the roller diameter. Very narrow cylinders require specific machines.
What is the working length?
The working length is indicated in the technical table.
For sheets longer than the nominal value, bending in multiple passes with recalibration is required.
Is it manual or motorized?
Benchtop models are typically manual, while professional models are motorized with electric feed.
Manual bending machines are suitable for small volumes and prototypes; for series production, motorized models are needed.
How much does the machine weigh?
See "Weight" in the technical table.
Benchtop models are installed on a sturdy workbench, while base models require a level floor.
