Case 3: Burrs are left at cut end faces. Why?
The probable cause is a chipped cutting blade or the deterioration of the bending wheel and
bending wheel guide (See the photo below).
Replace them with new ones.

If the backlash is too large when the cutting wheel guide is
attached to the cutting wheel, they are worn out. Wear causes gaps and
excessive backlash.
Case 4: Bending wheel guide comes off.
