How to diagnose a carriage drive fault on a BLM Group e-TURN / Smart tube bender
Carriage drive faults on CNC tube benders typically come from servo drive alarms, encoder errors, or lubrication starvation on the carriage linear guides. Check the servo drive alarm code first.
How to correct springback variation on a BLM Group e-TURN / Smart tube bender
Inconsistent springback between parts typically means the material yield strength has shifted between coils. Re-measure springback on each new coil and update the overbend compensation value in the CNC.
How to eliminate tube wrinkling or collapse on a BLM Group e-TURN / Smart tube bender
Wrinkling or collapse during bending indicates insufficient mandrel support or wrong wiper die position. Check mandrel position and mandrel lubrication before adjusting bend parameters.
