The slitter blade, also known as the slitter blade, is used to separate the steel plate into strips. After a certain period of use, the blade needs to be repaired due to wear and tear. Below, I would like to tell you a few things to pay attention to when the blade of the longitudinal shearing machine is being sharpened. First of all, the first and most important, most of the longitudinal shear blades can only cylindrical grinding, no grinding plane, because the thickness of the longitudinal shear blade size is fixed, if when installing blade grinding plane will cause not the dao, while the grinding cylindrical won't be any problems. Secondly, it is necessary to pay attention to the outer circle after grinding. Finally, after finishing the grinding, it is necessary to check whether there are any wavy marks on the grinding part. If there are, it is necessary to finish dressing the grinding wheel before receiving the light.
