Automatic feeding principle and solutions for feeding accuracy deviations in CNC pipe bending machin

English Keywords：CNC tube bender automatic feeding, tube feeding accuracy error, CNC pipe length tolerance

The automatic feeding system of a CNC tube bender ensures consistent tube length precision through servo closed-loop ranging. 

Most batch length errors are caused by roller wear, slipping, guide rail dust and parameter drift instead of programming mistakes.

Operators should regularly inspect feeding roller wear, adjust clamping pressure and clean guide rail dust to calibrate encoder data.

Anti-slip rollers and auxiliary pressing structures are recommended for thin and smooth tubes. 

Optimized automatic feeding greatly reduces manual measurement errors and improves the yield rate of bending, welding and assembly processes.
