What are the main factors that affect width accuracy when slitting a master roll?

1. During the operation of the slitting equipment, if the tool has the problem of lateral swaying, it will lead to poor scale, such as the lateral swing of the tool and the outer diameter of the tool are different and poor. Because the lateral rocking value of the tool cannot be zero. Usually the lateral rocking value of its load is about 0.03-0.05mm. The reason is the accuracy error of knife thickness, inner diameter, distance sleeve width, etc., and the warpage of lateral stress during thick plate shearing.

2. During the production of slitting machine equipment, because the steel plate has the problem of lateral warpage, it causes poor width scale. This is because the product cut in the transverse warping state is measured more than the set value of the knife.

3. Because with the production and operation of the slitting machine equipment, there are certain cooperation errors in the distance sleeve, tools, etc. Under normal circumstances, the thickness accuracy of distance sleeves, tools, etc. is 0.005. When the number of pieces is large, the cumulative error becomes larger. This is due to poor upper tolerance settings.

4. It should be known that the width of the product cut by the slitting machine is always slightly lower tolerance than the product side scale of the knife. Therefore, it is necessary to guess the extent of this difference in advance. When dispensing knives on the product side, the scale of the distance sleeve is confirmed and time-definct. Also take into account the chosen cutting method. In comparison, if the slitting machine equipment chooses straight-pull shearing, the tension of the steel coil increases, the lateral warpage will disappear, and the scale will go down.
