What to think about when purchasing a bending machine

When purchasing a bending machine, there are important parameters that should be considered in order to adequately compare machines from different manufacturers.

Important technical parameters:

  • Drive torque
  • Available bending force
  • Pump capacity
  • Flow rate in the hydraulic system

Important comparison parameters:

  • Operating costs
  • OEE (Overall Equipment Effectiveness)

Since calculations of capacity are done in different ways by different produces of bending machines, a purchase contract should always have stipulated requirement for the capacity and a demand for an acceptance test.

The acceptance test should clearly specify parameters such as:

  • Yield strength of the material
  • Bending radius to be achieved
  • Maximum remaining flat end by prebending
