Problem Probable Cause Solution
Wrinkles on internal surface Material size Use correct size tube
Bending pressure too low Increase counter bending die pressure
Tube slips Material size Use correct size tube
Poor quality tubing, die pressure is too low Measure tubing and replace with quality
tube, increase die pressure
Tube cracks or breaks Poor tubing quality Change tube suppliers or composition
Poor bend quality Die and former are touching or deformed Die worn out, replace
Tube wrinkles or is deformed CLR is too tight for workpiece Increase the CLR
Workpiece is oval or deformed Too much pressure on die Decrease die pressure
Workpiece ends oval or Too much pressure on die Decrease die pressure and use adjustment
deformed screw
Machine goes into overload Material over capacity Use roller style counter bend die
Machine goes into overload Machine needs voltage calibration Enter system tests mode and view
voltage. Measure actual incoming line
voltage with hand held meter. If actual
voltage is different from voltage shown
on system display, use (plus and minus)
button on control pad to adjust display
to actual voltage.
Die wears prematurely Too much pressure, not enough lubricant Decrease pressure and use lubricant
