Hi guys

I dont know if this is the correct sections to post this but I have an accurl shear that instead of cutting a 2mm thickness sheet is actually bending it

I have double checked the program the blades the nivelation of the machine and they are fine , the material Im triying to bend is black lamina I have noticed something tho

the machine cuts thicker sheets without issues
so I inspected the machine and noticed there is a gap in the cilinders of the top part in relation to the guide and according to my experience it shouldnt be any of that ( see picture attached)


any Ideas on how to fix this ?

I'm not sure what I'm looking at in the picture, but if this gap allows movement of the blade, it could be a problem. It sounds like the gap between the blades is too large. Is it adjustable?
 
FWIW whemn I was running a metal shear there was two things that caused rolled edges or bent material. 1. dull blades 2. the clearance between the shear blades was excessive. I would say blade clearance in your case.
