ZREMB GH4 tube bending machine, manufactured in 1983, is used in factories during the precise processing of all varieties of installation tubes. The tube bending is performed in a semi-automatic mode on a cam with the mandrel filling the most deformed section of the tube. The machine comes with a comprehensive range of equipment shown in the accompanying photos. The GH4 mandrel bending machine weighs 2450 kg.
The ZREMB tube bending machine consists of:
– drive mechanism
– mandrel feed mechanism
– guiding mechanism
– control panel mechanism
– hydraulic system
– electrical installation assembly
– frame assembly
